ok heres the deal..... i bought a 86 Iroc like 2 weeks ago with all intentions to part it out, but ive now decided to build it up again as a driver...Heres my question...im not sure about the trans in the car.. yes i know originally it was a 700r4, but im not so sure now...half the engine had been removed and the car sat for over 6 years. the guy i bought it from also bought it this way as well and never touched it.. all he can tell me is "supposedly" it has a rebuilt trans with a shift kit... but he said he couldnt prove it. Now today while going over what was left of the engine compartment i removed the wiring harness and could see the top of the trans....it has a large sticker on the bell housing saying "TS -Transmission Specialists" so im pretty sure it was rebuilt at some time...but i also noticed while most conectors left were attched, the wiring for the "700R4" was hanging free tucked up by the brake booster..and there seemed to be a vacum line that runs down to the trans. I never remembered a 700r4 having a vacumm line....Anyone got any ideas?? i'll look under the car tomorrow and i should be able to tell exactly what im dealing with, but i just wanna get an idea tonight maybe.....Thanks

 

a shot of the transpan would help a lot

 

i jacked the car up and just snapped a few blind shots under the car....this is the best one...its dark and getting cold out so i wont take a flashlight and crawl under there till tomorrow..oh yea...it also has an additional trans cooler installed inline with the one in the radiator...shows something has been done to the trans i think...on friday i just sold a 700r4 i had layign in my garage so im kicking myself that i cant look at it now to compare them

 

eh cant see 2 much basically all im lookin for is the shape of the trans pan.. makes it pretty easy to tell what kinda trans it is

 

here look at tcis website and look for the trans pan that matches the shape of yours.. http://www.tciauto.com/components/tr...ion_pans.htm.. from what i can see if it i'd say its a 350 or a 700r4

 

one thing...where does a 700r4 shifter cable mount? does it go front to back or vice versa?...if that makes any sense

 

I found out what it is....turbo 350...im excited...better than a 700r4 in my eyes...considering i paid 500 for the whole car and its in decent condtion...now i get a rebuilt th350 with a shift kit....cool...itll go perfectly with the built 350 carb motor im putting in...hehe...on back passenger side of the trans pan, it slants in the one corner, its not a perfect square like the 700r4 basically is...this pic i found online helped me....Thanks for all your help :lala:

you should check the amount of bolts on your transmission pan, the turbo 350 looks identical to a turbo 200 metric transmission, however the 350 has 1 more bolt than the turbo 350
