I just picked up my car after the 4.9/Isuzu swap. Everything is ood except when I put my car in 1st gear, it goes into what feels like 3ed. When I take off in first it can get up to like 70 mph. Is there a certain way that the linkage must be reattached? This is the same tranny that I had on my 3.4 that was flawless.
On a side not, when I first cranked it up and drove it, it was taking off in an even higher gear. We messed with the shifter some and got it down to third wich is drive able. What causes this? Is there some adjustment I need to make? Any help will be greatly appreciated.
Yup, mine has the same Isuzu 5sp...tied to a heavy duty rubber band (aka Iron Duke).
I'll have to get home by noon and see what I can get you right away. The scans may not be straight but they should look sharp. The book is falling apart. I got it 2nd hand with creases, grease smudges and all (I am sure the scanner will enhance these for your viewing pleasure).

Sounds like the problem I had after my swap. Check to make sure the linkage is attached to the tranny the correct way... Mine wasnt.. ended up I only had 3rd 4th 5th & rev... the linkage goes ON TOP of the Cable support bracket...not between the bracket and the tranny. I switched mine around..and shifts like its supposed to now....

This is exactly how mine is acting. Did your shifter go intop 1st and second but not really be in those gears?

I THOUGH it was..felt like it was..but actaully wasnt.. I took the cables off the shift levers and shifted it at the tranny by hand.. and could see the problem then.

Along the past 2 years, I've managed to find enough detail by consulting both, the shop manual and the catalog (and Chilton's, and the forum and heavens...but that's because I am a bit dumb).
With the amount of people that are helping you should soon be in good shape. Have fun!

Mine did the same thing when I first started my car. It turned out to be the cables on the shifter was backwards( The ones inside the car) ... I dont think the shifter assembly on the tranny is hitting anything. You don't have a crossover to interfere.
It could also be the linkage adjustment on the transmission shifter assembly. That's if you guys removed it any when the tranny was out of the car. It can also be that the shifter assembly on the tranny might of got bent when putting it in ( easy to do if not careful)
The goodnews is it's not internal... A broken shiftfork would make it nearly impossible to shift or disengage the clutch.
So in my opinion it's either the shifter assembly inside the car backwards or something not adjusted properly.

You just made my day. I feel much more confident now.

a shift fork is not a clutch fork - clutch fork is in the bellhousing - shiftfork is inside the casing.. a broken shift fork will in no way effect disengaging the clutch
i still think his cables are just out of adjustment - but he won't know till he gets in there and plays with it

My bad Kohburn ..... I mistakened the clutch fork from the shifting fork. I stumbled upon his thread and seen he had the same problem I did And kind of speed read all of it except for his post. I still doubt the shift fork is hte problem A shift fork would still make it hard to go into all the gears properly or jump out of gear wouldn't it?... if it worked when his 3.4 was in. My money is on something that's out of adjustment or cables backwards.

Bump. I had starting problems last night after messing with the timing and found some burt spark plug wires. Today I will change the wires and plugs and fire it up again. Then I will try to figure out this shift problem.
