Steve, could the pressure soleniod cause the stutter from a stop? Reason I ask is a certain white Regal (yes..still limping BTW, because it'* in line after a Park Ave
) was pulling that same thing. Overall there'* 16K on the trans since I picked the car up and it'* ... still working for the most part.
On the TCC.. let'* do this, what RPM do you have at 70mph after you've been up to speed about a mile? Reason I say that is..when you let off the throttle the TCC may automatically unlock and you might not be seeing it due to the method of testing.
