Question for the TH400 experts

[matt69olds]

What color spring do the TH400 experts prefer to use in the reverse servo(intermediate accumulator) in their street/strip 400 trans? I seem to recall reading somewhere that the yellow spring was used in factory high performance or heavy-duty applications. Secondly, when you remove the sprig (or place a spring behind the 1-2 accumulator valve) does the intermediate accumulator spring have much of an affect on shift feel?

Nobody????

Whats the deal? The tech discussion has really dried up here.

I'm far from an expert here, but I would try to get in touch with Chris from CK performance and see if he can give you some input

I don't want to call people at their place of business, they are trying to make a living and probably don't have time for a bunch of questions. I figured somebody here would have commented.

Chris is a member of this forum as well as a vendor. I've heard he's very helpful with this stuff.
