ive got an 83 chevy camaro berlinita and im trying to figure out what type of tranny is in it its got the squre looking type oil pan with all the corners is it a turbo 350 or 700r4 its the original one no changes have been done can some one help

 

TH250C

 

The TH250C wasn't used in a thirdgen, it was the TH200C and it has an irregular pan. The square pan with 16 bolts is the TH700R4.

 

700r4 = overdrive with four forward gears on the indicator plate and perfect rectangle shaped pan

thm200C = cut off corner shaped pan and 11 bolts and only three forward gears on indicator plate and was only in 82 and 83

 

yeah i think it is the 700r4 is that a good tranny...

 

the stock 700r4 on an 83 is a piece of junk lol.. i should know i have killed 1... better if you want a 700r4 for it to get like an 87+ case and have it rebuilt with some good parts.. then it wil be better..

 

As Fast68 suggested look at the shift indicator plate on the console.If it has 2 D positions(first one after neutral in a circle)then 2nd and 1st then you have the 4 speed 700R4.I believe this was the only auto trans offered with a V8 in '83(you could still get the 3 speed TH200C,and it was the last year for it in the Camaro,with the 2.5-I4 and the 2.8 V6 in '83).
It became a good trans but,as Angelis83 stated,the early stock versions(pre '87) left a lot to be desired.If it's shifting well,the fluid color is good and it doesn't smell burnt you should be ok.If you're having problems,check the tech articles here https://www.thirdgen.org/technical-articles and here 700 Raptor 700r4 700r4 Transmission 700r4 700r4 700r4 PATC 700r4 700r4 700r4 700r4 700r4 700r4 700r4 700r4 700r4 for good diagnose - troubleshooting guides.

 

i belive i have the 700 r4 but on the console i dont have two drives i just have one drive it starts from the bottom as 1. 2. 3. d . n. p. thats how it looks but when i get under the car its a completly squar pan...on the tranny... could i have possably gotten a 700r4 with out the overdrive.....??????????????????????????????????????????????????

 

There's no such thing as a 700R4 without the overdrive.

It's possible someone swapped a 700R4 into your car, but didn't put the correct shifter in.

 

the car is all oreginal no one has touched it so im really stumped on this one...

 

On the 83's the shift plate went like that. 1, 2, 3, D, N, R, P

In 84 on my other burly is went 1, 2, D, OD, N, R ,P

Same transmissions. Both stock transmissions.

So basically you have the right plate and everything... just in 83 they did not mark Overdrive as Overdrive. just drive... Since really there are indeed 4 gears.. and the 4th would be the overdrive.

 

I didn't see the "3" in there. :P It's a 700R4.

 

thanks so i do have the 700r4 but just auotamaticly goes into over drive is what your saying...

 

oh and when i want to drive out of over drive do i drop it into 3 or just leave it in d..

 

If you don't want it to go into overdrive, put it in 3.
