Transmission Converter Options

[ss3011]

I still think that this might work , with a 3.06 low gear and only running to 3rd . Big drop on the 1-2 shift which would need a looser converter to recover from , but the loose converter hurts upstairs with a heavy car , so lock up in high gear and get your mph back . Its worth a try , just need a converter company willing to help .

Just on the drag factor a 200 should be a day and a half faster than a 4LE60 or us idiots have been doing it all wrong.

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.
