I have an 89 gmc van w/700r4 I would like to take it out of my van and put it into service w/ my 89 gta will these inter change?

 

Yes

 

Thanks for the info I find of thought that it might being 5.7 to 5.7 same year and all, but I was just concerned about the van being 3/4 ton going to a third gen maybee it will being a little stronger?

 

You'll need to swap the tailshaft housings to mount the torque arm, and the speedo gears.

 

thanks apeiron that is the kind of stuff I was looking for as I've never done this type of swap, I guess I'll go buy tailshaft housings. Do you know about what they run denero wise? I would have eventually figured out what was up but I do love this site as it is nice to have all this knowledge at my finger tips Thanks again

 

Free, if you already have a 700R4 in your car.

 

thanks again and I do but I just got my 383 and was worried that it might not last and I want to have beefed up back up tranny

 

The tailshaft housing isn't an item that's prone to breakage.

No stock 700R4s are particularly strong. If you're worried about it, you should have one built up to suit your needs.

 

Hey apeiron, since you answered my thread is there any way you can teel me what I have to do to get my tranny to shift when I get my motor in it as I have gutted the wiring so to speak, no more eng conrtol, went to msd billet ect. will the comp still shift the trans or what? thanks a mill

 

I just wired one to work the lock up in 4th gear only per customers request. Terminal a on the lock up plug will need 12v ignition power. Then wire terminal a in the trans to the positive lead on the solenoid. Put a normally open switch in the 4th pressure port and run the ground on the solenoid to the terminal on the pressure switch. More than 1 way to get lock up. This is just 1 simple way.

 

The computer never did shift the tranmission, the only thing it has any control over is the TCC lockup. Floor Guy's method to get it to lock in 4th works just fine. It would have been nice if you hadn't hacked the wiring out, you could have rewired the inside of the transmission and reused the external transmission wiring with only some minor changes.
