200r4

Was the 200r4 used only one year in the corvettes. Some late 81's and
1982. If so, what other GM cars & trucks used this tranny.

200r4 = never in a C3. 82 came with a 700r4 that continued a few years into C4-land.

TTT for the answer to your what-other-cars question.

OK I was confused. I did read that a 200R fit the C3 bodies easier
than the 700. If so and the 82 was C3 that why is this.

82 only came with first year of Cross-fire FI, an automatic, and really low rear-end ratio (low numerically, 2.72 or 2.87).

Yes apparently the 200r4 is an easier "swap" into earlier cars and makes more sense with higher gears in the rear end..

In 82 Corvettes the only transmission available was the then all-new 700R4. 84-91 Corvette also had it as an option. 92-93 is called a 4L60 but is basically the same transmission with a 5-pin connector instead of 4. 94-96 got a 4L60E which is an electronic version, but shares many parts with the 700R4/4L60. 88 up are stronger and are the ones to get.

The 200R4 was never available in a Corvette, behind a big-block, or in a truck. It is a good transmission WITH MODIFICATIONS and rebuild. It is the transmission of choice for Buick GNs. It is not strong in stock form. It is shorter than a 700R4 and thus is almost a bolt in swap for a TH350 or 4-speed.

There are many posts and many opinions on which is better. Do a search.

Thanks, My 81 had a 287 rear I believe so the 700R4 would be better
with this low ratio. Is the tunnel the same on a 81 82, if so I could set
it up like a 82. I read of a company that sells all this stuff but cannot
remember the name.

I have posted many times here on this topic, and I think the 700 I installed some 8 years ago in my '72 here was a mistake....336 rear...and the first gear is/was allways useless as the shift happened in 2 seconds or less....the useless 3/4 clutch pack is another failure item with about 6 'fixes' posted on all sorts of places, and yet it still fails....I was not putting in the 4th clutch pack, I even had the parts...said screw it, I"m doing my own rebuild with a Trans Go shift kit, and hell with the 700 IMO, being some 50 lbs lighter, the 200 4r is the way to go....I had to widen my tranny tunnel some 2 inches on the pass side to clear that band apply valve, and pan....not worth the hassle....

SO, I guess this latest escapade willl tell the tale, IF I got that 200 4r rebuilt right, I no expert on these, but followed directions and asked questions....

I have a 700r4 in my 79 (previous owner installed it) and it hauls A$$ off the line with stock gearing (3.55) and almost no other mods.
