200r4, 700r4 how are they different?
I am considering an overdrive tranny to replace the T350 in my Studebaker. I am not at all familiar with these units, can someone tell me the differences, what cars they came in originally, what are the plusses and minuses of either one. Personal experiences would also be great to hear
Thanks
Pat

200r4 is a smaller, weaker version of 700r4. It was used in 4 cylinder and 6 cylinder cars and mini trucks, while the 700r4 was used in anything full-sized or v8 equipt. Sure, you can build a 200r4 to work for your application, but it will be cheaper to buy a 700r4 that is come strong enough from the factory. If I had a lot of money, I would keep the turbo350 and buy a add on overdrive; it's only $1700 if I remember.

TH200-4R & TH 700-R4

The main external diffenrence between those trannies are the length! TH200-4R doesn't have the replaceble tail like other trannies so it is about an 1" shorther than TH 350 with short tail.
I replace the powerglide with the TH200-4R on my 63 Impala few years ago and It works great! All I had to modify was the transmission brace!
The TH200-4R that I had came originally on Olds Custom Cruiser (307 Olds sb V8) and It has all bolt circels (Chevy and BOP).
TH 700-R4 came firs time in 1982 and it has the same Lockup converter as the TH200-4R untill the mid '80s.
TH 700-R4 Is longer than TH350 with the short tail.
If it's the same length as the TH350 with the long tail, I don't know???
If you're going to install TH700-R4 I suggest '88 or newer from the Diesel Chevy Van and build it to match your engine and differential ratio!

I had to go to the doctor's this morning. He told me that my sugar was too high so I came home and put it on a lower shelf. I feel better already.
