My bro has a 87 GTA, 355 - supercharged - and has been through at least 7 rebuilds of a 700R4, including two different trannys. Now it's out again. He doesn't want to stick another 700R4 back in there, what are his options as far as putting a Turbo 350 or 400 in there? How hard of a retrofit is it? Are they that much better of a tranny for a car that eventually will hopefully put out about 400 - 450 hp? What's the limit on a GOOD rebuilt 700R4 PROPERLY rebuilt, I don't think the f00ls that rebuilt the tranny the 7 times knew much about it. I told him to rip out the 700R4 and put in a 5 or 6 speed, but oh well.

He actually took it to two different tranny places, both having ****ty luck. This last time they put in some type of **** that made the car not even kick down to the next gear, in order to "save the tranny"....whatever.

His major limitation is $$$. He's probalby looking at spending $800 TOTAL, parts labor etc for putting it in and buying the tranny.

Thanks guys

 

pretty easy to do, not sure about the 400, but use the longertail shaft 350, 9" i ithnk and buy a b&m pn30299

if you can get a 400 go for it it is supposed to be "bullet proof" well thats what I have heard but, never sreally saw too many of them. other wise the tail would be the differance and if you can get a th350 to fit than the 400 should as well.

 

outch 7 times!
yea you can proabably find a good used 350 at a junk yard for less than 500 bucks.
try that. i know parts stores sell waranty rebuilds for turbo 350s for around 600 or so but you need a 350 core. you think they would be glad to get a 700r insted of a 350 but there not . 350s can handel about 400 hp but i wouldent push it past that.
For the love of god pep use a trans cooler before you have problems

Fried the tranny this morning for the second time in a year. I'm not screwing around with a local rebuild. I'm buying a new tranny and torque converter from TCI. Also the problem with the tranny might not be the tranny at all but a sorry torque converter which will kill a tranny.

 

uhh...my friend got a 350 at a junkyard for 25 bucks....it was 50% off day..so regularly 50 bucks...you gotta remove it yourslef though....pick your part>

 

Flash, I tried TCI's tranny, and I had nothing but problems with it. Didnt shift right. Every shift was like the tranny mount was broken. It was supposed to be a lockup, but had no provisions for the ECM, so you had to do it manually. I just thought I would warn you. It took me no longer than a week to yank it out and get rid of it.

Don't waste your $$ give F.C. www.thetrannydoctor.com a call or visit. His tranny's will hold up to your abuse. Cheaper and higher quality than TCI.
