Hi, I am putting a 93 lt1 trans-am700r4, into my 87 iroc-z with an L98. I have already removed the tail shaft housing, and installed my 87 irocz's mechanical drive assembly with my gear I need in the 93 trans.

What I need help with is making sense of the 5 wire round connection on the 93 trans am, I need to convert my 87's to the 5 wire harness. I believe 1-2 of the wires is for the trans temp sender for the computer idiot sender.

If Anyone has done this swap, let me know I am going to put the trans in tonight, so let me know, thanks, Keith.

 

I just did this on my 90 it was pretty easy really. the wire colors are the same if i remember right. just pull the pins from the Iroc one and install them into the five pin from the trans-am. that way you dont have to cut any wires.

Sallee Chevrolet - Performance Parts Catalog this link has some info on installing one. Look under salle and gmpp

 

Hi, thanks for some info.

Well the problem is that the 93 trans, has a 5 pin connector, I have 3 on the iroc, which pins go where?

the iroc has a purple, tan/black, and a green wire,

the 93 t/as wires are:white,green/white,tan/black, light green and green/black. Which of these wires should I switch with the irocs wires?, which ones do I remove from the 93 700? Thanks Keith

 

hi keith... only three of them are used in the 4 pin. Heres is a pic of mine. just pull yours from the 4 pin and install them the way mine is in the 5 pin connector. these are my factory wires from my 90. if you have the same color wires you should be all set. i think you can get one of those pin tools from your local auto store. makes it alot easier to swap them might be able to use a small screw driver.

Hey whats up? I'm back this weekend, I'm going to swap the wires, and the tv cable, and take the car out for some driving, I'll let you know how everything works.

 

Good luck hope it goes well. look on that site under salled and gmpp. then under 4l60 trannies. They have instructions for installing a 93 into the earlier cars.

you may have to swap out a valve for the convertor clutch to work right. not sure though, mine was all setup for the 82-92. And works great..if you have a problem with the convertor not locking then thats why. again im not sure i didnt fully understand the instructions myself. Maybe someone else who has done the swap can chime in on that. it maybe just for the non computer cars.
