so im going to pick up an f23 tomorrow with 80k miles on it to mate to my 4.9, so naturally i did some searching and found some things out and have some question hopefully you guys can help me with.

the f23 has a hydraulic throw out baring, so theres no traditional slave needed corrrect? how do i adapt the fiero line to the new transmission will i need adapter fittings?

i read on one of the threads that a guy broke the case around the axle barings and chiped off some gears running 375 tq to the wheels but on the same page i read a guy is talking about putting his fiero sideways with 600whp and not having any problems. so whats the story? i read that its only rated at 170# of torque no more than the 282 but will i have to worry with a 4.9?

as far as im aware the axles are the same so thats good but the clutch pressure plate will need to be ground down a bit as it hits the bellhousing. i have a fiero store hd clutch probably no to differnt from the spec slutch i saw that had highlighted areas to grind down but how can i test to see if the pressure plate is hitting the bell housing?

shift linkages......im going from an isuzu 5 spd to this does it have the same shift cables as the 282 from our fieros so that i will have to buy another select cable? or can i use the ones from my isuzu?

shift linkages continued.......brackets so ive read theres no tried and true method of shifting this tranny what kind of brackets have your guys built that work? any dimensions or whiteprints availible? i can weld and fabricate just fine so skill isnt an issue and i can probably figure it out if no one has anything readly availible all i would need to know is what posistion the shift brackets would be in for what gear, as transmissions ar my weakest point.

bumpity mc bump bump before i head to work.....yes i kill zombies on the graveyard shift.

I wouldn't call myself a guru, but I did do this swap earlier this year. 2000 Cavalier F23 in place of a bad 282 behind a 2.8.

If you can't get the hydraulics from the donor car or junk yard, you can get the whole system from rockauto for a 2000-04 Alero:


All you need is the part at the end, then just adapt it to your existing hydraulics with compression fittings.

2 select cables for a 282 are needed. Rodney Dickman will install the removable ball end at your request to allow installation onto the built-in ball on the shift lever.

No, you won't find any drawings. Here's what I came up with, it has held up for a few months so far:






These 2 pics were before the additional gussets were added to the bracket, and before my 2nd select cable came in, so I used the 1 cable in each position to show the layout:





Notice the select linkage had to be reversed, otherwise the shift pattern would be backwards.

thank you kind sir you have provided invaluble information for me! +1 for you. i dunno if the junk yard will have the hydralics but ill try and find it if i order it i order no biggie.

A shift cable wont reach. The F23 needs the cables to come in from more of an angle.

Good idea with the TOB spacer. I found that a pedal stop would also do the same function in a different manner.

As it turned out in my original setup, the htob was only barely compressed. So then any pedal application moved it easily to the end of its travel.

whats the word on the livespan of these trany's? ive been trying to find one with the lowest milage possible but im getting between 80k and 110k which is reasonably expected of course. but i was just wondering.

This transmission is not a good choice (ratio - wise) for the 4.9.

Per your other thread concerning transmission ratios, the 282 Getrag will be a better choice for everything other that interstate highway cruising.

ya thanks i wish i had another option i cant find any 282 within a reasonable distance. i dunno i prolly wont end up buying the f23 at this point just searching waiting to find something.

4 speed should hold up as long as it's a V6 4 speed not a 4 cylinder 4 speed.

The best of all worlds for the 4.9 would be a 5 speed with the Muncie 4 speed ratios and a 5th that was about a .65 overdrive, but............

The 4 speed is an excellent choice (ratio-wise) with the exception of a lot of RPM at interstate speeds.

And it's a strong transmission if you aren't shock-loading it.
