Transmission Converter Options
 
I am running into a new issue.

Currently running a 4L60E trans and Yank PT4400 Locking Converter
Needs more converter but nobody makes a higher stall speed Converter.

Which makes plans to move up to Stock interesting.
I like the programmability of the 4L60E.

So what options are out there?
Also will I need have drive shaft issues?

Dan,
You have really answered your own question ; purchase a good turbo 200 and you will have any of a number of convertor shops to choose from .The reality of stock eliminator is if you don't do it right the first time you will be sorry .

What do you need a lock converter for? You won't even use 4th anyway.

For one...You can gear it like a Manual.

Most race manuals use a direct 4th. You can under drive an old Nash or maybe even G-Force, but not overdrive it.

Come on Mark , a converter clutch will certainly be more efficient in high gear , the question will be how it will effect the launch with all that extra inertia on the turbine .

When I ordered mine from ATI they suggested to lose the lockup and go with an 8" and for that exact reason with the reduced weight Charlie felt it would work better overall.

Russ, I have never thought that a deal like that absolutely would not work in Stock.
However, what Dan has on hand may work in Pure Stock, but it's all wrong, wrong, wrong for stock eliminator. You know that.
We're not trying to re-invent the wheel here. Just run a couple of tenths under the K/SA index. That is, I think that's the plan.
Going to have to agree with Brian here. Just set that o/d., lock up deal under the bench for now.
