So. Like it or not, its time for me to do ANOTHER transmission swap / replacement.
It seems that my freshly rebuilt Getrag (less than 400 miles) has leaked fluid all over my brand new Spec Stage 3+ clutch (rendering it "good for nothing" now). Im not too happy about it! So, most likely, the input shaft seal (unless the case has a small crack?) is leaking and the clutch is bad, I might as well go for another more reliable transmission.

My first thought was an automatic. Probably a 4t60 or similar. The more I thought about that, the more expensive I thought its going to be (not to mention, I know NOTHING about automatics).
Then, I thought about the 6spd transmission. I am aware that V8 Archie has a kit for it - that could make it atleast a little bit easier, and that makes me pretty happy!

I have a 350 c.i. V8 that I installed using an Archie kit. I currently have a Getrag 5spd, but need to change it...

I did a search and found alot of information about the 6 speed swap, actually, I spent the last 3 hours reading through those threads.

For anyone who has, or has done a 6spd swap:
-Can anyone tell me what they think about their G6 6spd transmission?
-How hard was the install?
-Did you use Archie's kit? Is there anything else that you need to get to put the transmission in?
-Do I use the Fiero's clutch hydraulics (line and master cyl)
-Do I need to modify or cut and remove any part of the frame / or sheet metal?
-Exactly what year(s) does this transmission come out of (so I know what to order, I plan to get one from a dealer)
-Anyone have any advice about this transmission?
-How does this transmission hold up to power from V8's, 3800's, or other Fieros with alot of horsepower?
-How has this transmission held up to abuse from same motors?
-Anyone else have any opinions of this transmission?

Please share any information that you may have about this transmission and or swap
Thank you to all who reply!

Talk to Archie he does them and has all the adapters you will need for it.
since you already have the V8 you will not need a few of the parts.
he will also convert the shifter for the 6 speed.

Yes I like the transmission, just wish the trans-axle final gear was about 3.0 to 1 but you can not have every thing when out looking for something that you can swap in and fits. Other than first gear being to short it is a great transmission. I use the Fiero's clutch hydraulics, you will need an adapter to connector it to the through out bearing. Can not tell you much more as mine is behind a 4.9.

I've asked a few times on here if anyone had a tale of woe about breaking one during hard use. So far nothing.

My next step is to talk to Archie. Im just doing some research now and trying to find out a little about the transmission, especially the durability and how it will hold up to any abuse (or is this transmission going to be like the 'ticking time bomb' getrag that I currently have - long story.....)

Thank you JGunsett - you have a p/m

Saboo...
I missed you at Lititz. I wasnt able to meet you (you were there, right?) I would have liked to talk to you and atleast thank you for that aldl computer cable!
As for the 6spd transmission, are you gathering info also? Or have you done the swap or are you in the process? Let me know, any info that anyone has gathered and can share will be helpful!

-I think it's the best manual transmission option for the fiero. Gearing is fine, it's strong, it's new and it's cheap.
-Install isn't that hard.
-Didn't use archies kit so i had to do everything myself. Only thing i outsourced was the splineing of my new axle shafts
-Fiero clutch master works fine but it moves the TOB farther than you need.
-No idea what other mods are needed for a SBC
-Mine is an 06
-No other advice
-It's holding up fine for me with a 305rwhp northstar and over a year of autocross racing and daily driving on it (daily driving might aswell be be racing).

I installed mine using Archie's kit. With the kit it is almost a bolt on. Piece of cake. I love it. Mine is an 06 and to me feels like the getrag but with a true overdrive. Working fine holding the 367 rwTQ of my V8

Alex - YOU are the guy I need to talk to about this!
Your V8 is similar to mine (yours probably has a goood bit more power, so you'd be good to talk to)
It sounds like you like the transmission.

What is your driving style? Have you ever raced it? I dont care about times (this thread isnt about that) I just want to know if it can hold up to a little abuse! Not constant abuse, but I dont want to be scared to push the throttle down more than 1/4 of the way!

-Where did you get your transmission?
-Is there any advice that you can give before I start gathering parts?
-I will get the Archie kit, but what else will I need to have other than the transmission?
-Approx. how long did it take you to switch to the 6spd?
-I have my front V8 mount welded to the cradle, will I have to move that? Otherwords, will the motor have to move at all, or will it stay the same place as it is now?
-Do I have to modify the cradle or frame or any sheet metal in the engine bay?

Thank you very much for replying!
And please give me as much info as you can, or point me in the right direction to get the info (I do know Archie's # and website.... im gathering information and $$$ at this point)

I purchased one from this guy a few weeks ago. Very good to deal with and the Transmission looks good.

https://www.fiero.nl/forum/Forum4/HTML/046878.html

I have not installed it yet. I intend to put it on my 2.8L daily driver.

Thats alot cheaper than getting it from a GM dealer!
Do you (anyone) have any idea why / how this person can sell the EXACT SAME brand new transmission for less than 1/3rd of the price that the dealer offers it for? I got a quote of $1850.00 from a dealer.

Is there something wrong with the ebay transmissions?
I surely do NOT want to waste MORE time and money and swap in a possibly junk transmission, or even a transmission that has some kind of defect!

The Ebay transmissions are the same one you'd buy at the Dealer.

Basically it goes like this....

Between the 06 & 07 model year Pontiac (GM), in their infinite wisdom to find a way to go bankrupt yet this decade, Changed the gear ratios ever so slightly. That caused the 06 transmissions that GM had in the supply chain to become surplus. Usually when GM has big surplus lots, they sell them by the truckload to the highest bidder. Only the person who bought all of them know how many there were in this lot. There could have been 200 or 2000 or more, no one knows.

Anyway the junkyard that got them has been dealing them out to wholesalers who have been putting them on EBay.

As far as the quote you got from the dealer, that's in line with what I paid for the 1st 7 or 8 that I bought for conversions before these surplus units started showing up.

So, it seems that the unit that I found on ebay should be a good deal.

Archie, are these "reduced price transmissions" the same ones that you've been using lately to swap into Fieros? Have you had ANY problems at all, or anything that you could point out to look for? Any precautions that I need to take?

This is a swap that is going to HAVE to happen. I just need to find a way to get the money - done it before - gonna do it again!

Archie, you have a p/m
Thanks for the response and explanation of the ebay transmissions!

Yes, I've had a lot of customers have those EBay transmissions dropped shipped here for the conversions. I've also bought about 30 transmissions for myself out of that same surplus lot. Because no one knows how many of these transmissions were in the surplace lot, I bought up a bunch of them when they 1st started to become available. That was before they started to appear on EBay. The bad part of that is that I paid an average of about $800.00 each not knowing that they'd get a lot cheaper as time went on. As I've said before, no one knows how many of them GM surplused, so I bought a bunch of them early on. When the ones on EBay stop appearing (when the lot of surplus runs out) then we'll have to go back to paying thru the nose to get them from dealers.

If you have a notion to get one, I'd say get it now because one day the surplus lot is going to run out.

The only problem that some people have had with them (just some of them NOT all of them) is a rattle when the engine is idleing in neutral. Note that some of the new dealer supplied transmissions hve had the rattle too.

It IS NOT a FATAL rattle.

Because of the fact that I have a cutaway transmission here to look at, I've figured out excatly where the rattle comes from.

One of the shift collars in the case moves (or floats) back & forth about 1/16" when there is no load on it such as when it's idleing in neutral.

This is the one that rattles......



On the ones that rattle, if you just put a little movement on the shift lever the rattle stops.



I would guess that if it really annoyed someone, they could put a light spring on the shift lever & it might stop the rattle.

I've got your PM. There's a lot of info I've got to answer in it & I'll try to get to it today.

We've been pretty busy the last few days test driving 2 cars that will be at the Dells. Test driving a 383 6 speed & an LS7 6 speed is a hard job but somebody has to do it.

Some answers:

-Where did you get your transmission?
Ebay. Bought two to have a spare

-Is there any advice that you can give before I start gathering parts?
Borrow from your 401K savings account. You may need it

-I will get the Archie kit, but what else will I need to have other than the transmission?
The kit will have all you need assuming your V8 conversion is complete. But upgrade to a stage 4 unsprung clutch. This probably is the most important advice I will give you.

-Approx. how long did it take you to switch to the 6spd?
Is hard to tell because I did engine parts upgrade at the same time. But I would say it would take maybe 25-35% longer than a clutch job for measuring and welding the mounts and shifter swap.

-I have my front V8 mount welded to the cradle, will I have to move that? Otherwords, will the motor have to move at all, or will it stay the same place as it is now?
That is not a problem. It will stay in same place.

-Do I have to modify the cradle or frame or any sheet metal in the engine bay?
Yes. The F40 rear is bigger and as you know in a V8 swap it is moved to the driver side. So you will have to cut like a notch in the lower driver side frame rail and box it. Archie's video explains it well. That probably may be the hardest part to do of the swap. You will need a welder for that and for the mounts.

On the others, I drive normal. Not like a maniac but not like a grandpa. Reason is there is a LOT of cops where I live (too much spare budget from property taxes!). I have raced on street couple times but I have shifted hard (1/4 mile type) several times. Not on the track yet. I have no doubts this trany will hold spirited driving unless you put slicks and dump the clutch at 5000 RPM on a sticky track. In my case the tires are the fuse. You should be fine but please remember to upgrade the clutch as I told you above

one concern, when you google the clutch that you have recommended above, this is what you find :

"Stage 4 Unsprung Semi-Metallic Kit:
For heavily modified engines or engines of any modification level being used for drag racing ONLY where an instantaneous engagement and light weight are beneficial. Spec's Stage 4 is unsprung, making it extremely difficult to use on the street and very noisy.
KNOW WHAT YOU ARE BUYING: JSC Speed does not recommend the Stage 4 clutch for 99.9% of our customers due to its difficult drivability and stress to the driveline; purchase at your own risk. Includes high-clamp pressure plate, 6 puck carbon semi-metallic friction with high torque rigid hub and carrier assembly, bearing and alignment tool."

. . . and this. . .

"For heavily modified engines or engines of any modification level being used for drag racing ONLY where an instantaneous engagement and light weight are beneficial. Spec's Stage 4 is unsprung, making it extremely difficult to use on the street and very noisy.

Torque Capacity: 530 lb/ft

JNA Performance does not recommend anything above Spec's Stage 3+ unless your car has improved driveline and transmission components and is a dedicated drag car (no street driving, etc.). Stage 4 and 5 clutch kits are unsprung making them noisy and harsh and unsuitable for street use.

JNA Performance does not recomend this clutch to all its customers for its difficult drivability and stress to the driveline; purchase at your own risk. Includes high-clamp pressure plate, 6 puck carbon semi-metallic friction with high torque rigid hub and carrier assembly, bearing and alignment tool."

. . . and many other warnings on numerous websites.


this is for my husbands car, which has sadly broken our bank accounts way too many times and i really don't want to see it happen again. he doesn't plan on racing it. he plans on driving it. this clutch specifically states that it is not supposed to be used for street driving.

any advice or suggestions of a different type of clutch to use?

chrishahn87 asked for advice and recommendations and I gave that based on my experience with numerous clutches on my V8. Clutches is a touchy topic here and you may get many many different opinions. My car puts 366lbs of torque to the wheels. Torque is what provides the force to move the drivetrain thru the clutch link. I broke everything with a spring. Initially I was afraid that the unsprung stage 4 would be a beast with a lot of chatter etc. I was pleasantly suprprise that it is not. It feels the same as my two old stage 3+s and a Superior Friction I used. It grabs quicker but has no chatter. So based on that it is why I recommend this clutch to anyone with a high torque engine instead of going dropping cradles to swap broken springs clutches.

Thank you very much Alex for the reply and the great information!

Thanks for the info on cutting the "frame" part. Thats no problem. I can cut and weld all day long! Im good at that!

The only "problem" that I have is the clutch issue.
First... Do I use a clutch for the Fiero - if so, what year / motor / transmission? If not, then what make / model do I need to ask for to get for the correct clutch?

I am going to be buying Archie's kit, which says it comes with a clutch. Is that clutch not good enough?

The clutch that I currently have in my V8 Getrag is a Spec stage 3+. Before it got the oil on it, it definatly held very good and did not slip at all during the hand full of times that I *barely* got on it. The problem that I have with that clutch is that it was kinda harsh. Really, it was a pain in the ass to drive - leaving any stop sign / traffic light / traffic driving, etc was a P.I.T.A. because the clutch was either ON or OFF with NO in between or smooth transmission between clutch pedal in or out.

Alex: Since you had a stage 3+ and a stage 4, can you tell me the driveability differences while in traffic? How much different is the stage 3+ from the stage 4 (other than the holding power)?

I understand why I would want / need an unsprung disc considering the torque of the (non stock) TPI motor. I have never driven anything and I dont know anyone who has had a car with an unsprung clutch, so I am not familiar with it at all! Any more information about that clutch would be helpful!

Thanks again to all who reply!

The Clutch Alex is talking about is the same one I now send out with the 6 speed kits.

I agree with you Chris, when you talk about the Stage 3+ being an on off switch. I felt that way too. However, it dosn't seem that way on the 6 speed. Maybe it's the fact that the 6 speed uses a Hyd. T.O. Bearing or maybe it's just me...... I'd like to hear Alex's opinion on that.

On Troy's LS7 6 speed car we used the next step up from the one Alex is talking about & it drives great.

Archie,
So, you used the Spec stage 5 on the LS7 car? Im sure that I dont need that kind of holding power, as my motor is not making anywhere near the power that an LS7 does!!!

Also, I watched the video of that car being test driven. I noticed a "whine" that seemed to be associated with the rpms of the motor, as if you either have a whiney transmission or cam gears. Can you tell me where this noise is coming from?

My current and last getrag had that same whine, but it was usually only on light acceleration and ALL deceleration. When I called the company that rebuilt the transmission, they said that it wasnt supposed to make a noise like that (getrag) and should be looked at - which caused me to have to remove and return the transmission for another that had the same noise, just less.

I don't know if SPEC calls it a Stage 5. It does have a beefyer (< is that a word?) Pressure Plate than the one I normally use for the 6 speed kit. It is a taller clutch & if someone is planning to use it then I need to know in advamce because it requires some other adjustments to parts I supply.

My cheap camera catches a bunch of backround noise. In fact at one point in the video you can even hear Rob's heartbeat when he had his thumb on the little holes in the camera case where the MIc. is.

There is a little whine in the car that you can hear. And it does go up & down by RPM. However it's not the transmission. It does sound a little like a Gear drive on a cam but the LS engines all use a chain cam drive. The whine is either the dry sump oiling system on the LS7 or the Power Steering pump that is mounted right behind the bulkhead on the passenger side. There is no way to test for either one of those items because you can't disconnect Either (or both) & test drive the car.

I am familiar with the Getrag whine you're talking about. Back in the day, (20+ years ago) when I drove my 1st Fiero Getrag,I thought it sounded like the old "Rock Crusher" 4 speeds from the '60's.

Hope that helps

Archie

Chris, then you are fine to go The Stage 3 I used on my Getrag chattered a lot. The Stage 4 I have can be launched smoothly. It grabs quickly but I wouldn't say it is an on-off clutch. There is always a compromise and with a V8 and small disc like the one that fits our cars you won't have a true stock feel to it. But I bet you won't be disappointed with the Stage 4.

Im glad to hear that the 6spd transmission is not known to whine! And im also happy to hear that the whine is coming from somewhere else - either suggestion could be the culprit. I couldnt tell you how annoying that was with these last two getrag transmissions and their whining!

I am not new to getrags (im also not an expert by any means) but I have had two different Fieros both with unmodified, non-rebuilt, original getrags in 2.8 Fieros and I have never noticed a whine or really any noise from them. That is why I was so concerned with this freshly rebuilt FWD getrag that was whining. Either way, no problem, because im taking it out and never gonna deal with it again!

I'll keep the comparison of getrag to "rock crusher" (im familiar with the straight cut gears) in mind for future knowledge, and just accept that it is how it is supposed to be!

Alex,
I will be using the clutch provided in Archie's kit, so I guess Spec stage 4 it is! As ive said before, I am not familiar with the unsprung clutch disc(s), so I just assumed that it would be too aggressive or too much of a pain in the butt to drive.

The hydraulic t/o bearing? Good deal! I cant wait to get this started!
