    3400 stall and shift kit?

    I have a 3400 2.1 STR Fuddle stall in my 02 Z28. Lately have been getting that pwm shudder in drive on the street(normally in D at around 2k rms and I hit the gas a little) at WOT and if I shift the car myself it doesn't happen, is when it searches for what gear it wants to go into. Since it is my daily driver I want to put a shift kit in to cure it. I don't car about hard shifts, just want the pulse width modulation cured and slightly firmer shifts. Will the SK 4L60E Transgo kit work or would I need another.

    I ended up putting in the SK Transgo kit... PWM is gone and the only real difference I feel is a little firmer 1-2 shift... I was only after taking care of the PWM problem, so at least it solved it..I'm happy
