Totally agree with you . I had probably the first stocker to run a 200thm in my 83 307 Cutlass . Definitely faster than a 350 or a 400 .

I think Dan wants to work with a 4L60e , and that's cool too ! There are a lot of large diameter steel drums inside that beast , and I am not sure if any aftermarket company making aluminum replacements .

4L60E is what I have and know and it is built up.
For now going with what I have.

A built 200thm costs a good bit.
The R700 and 4L60E are stronger, right now prefer reliability.
They have similar internals.
Should already have some light weight race components.

This is a good conversation.

Feeling pretty good about my current Coan Lite TH350 w/low gearset vs the metric 200 so far.

I know someone with a 200 for sale with only 4 or 5 runs on it.

Coan makes good transmissions!
Liked them when they started business in the early 80s.

The Metric 200 is fine for a lighter car.
4000lb plus weight you need a wider clutch and HD internals.

Yes, durability was the driving factor for my switch to the TH350 vs the metric 200. Not realizing any performance loss so far with the change...but my junk has always been slow.

Don’t dismiss the 200 if it’s built right. My p/sa car had it from corbitt, when it was above 4000 lbs. They are also used in a lot of heavy cars in stock like some copos. Turbo action did my 200, jack sepanek fixed my pump after 8 years problem free. My little 265 qualifies very well with a 200.

If you are having trouble with a 200 Metric it is not the transmission. It is how it is driven in the pits and water box, chassis flex or transmission assembler. I get 200-300 runs out mine all the time and take them out because I am embarrassed that I haven't had them serviced! Paul Forte builds a great transmission.
