Identify this transmission?

[GroceryGetter83]

This came out of my 1983 Cutlass Supreme, GM 231 V6 car. I thought it was a TH200 but it has a removable tailshaft? Does that make it a TH350?





TIA

It's a TH350-C , which means its a th350 with a lockup torque converter.

 

[olds307 and 403]

Is there a stud by the cooler lines? That makes it a much less desirable TH250C. They are a reliable trans behind low power. My 81 Delta 88 had one last over 400,000 km with a stock 307. It lasted one day behind my 403.

like olds307 said could be a th250c they are almost Identical . with a V6 more likely a th250c

Check the bottom of the pan. If embossed with the word "METRIC" its a turbo 200. Turbo 350 should have a flat non embossed pan. Also as olds307 and 403 stated look for the bolt on the side of the case for a turbo 250. From your pictures it looks like a turbo 350.

No stud:



Guess it’s a TH-350?

Also, as an identifier, TH250Cs have a pan with ribs embossed in it, where TH350/350C have a flat-bottom pan

My understanding is that in Chevrolet applications through 1981 model year, 231 and 267 cars got TH350s, the 229 and 305 Chevs got TH200s, although GM documents indicate in some applications, it was manufacturing's option as to which trans went in.

By 82, only diesel Chevs got TH200s, my 3 '83 wagons with 305s got TH250Cs

It’s also has a flat bottom pan.

Is this worth anything to someone here?

I believe all 350C's were universal bellhousing cases as well.
