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?
