Exclamation Noise on 2-3 shift

I have a 98' T/A with a Trans Go shift kit, and a 2800 stall converter. New after market driveshaft. Problem is on the 2-3 shift and only when going easy on the throtle I get a noise. Something like a dull thud. Under harder accelleration no noise. It could be from the trans or from the rear end hard to say the way sound travels. would this be normal wiyh a shift kit?

Well if you have and aluminum shaft you may just be hearing some noise transfer from a clunk on the 2-3 shift. Without hearing it I am only guessing though wildley

The after market shaft is a steel shaft. Is this clunk normal?

still just may be some noise lash transfer. Remember 3rd gear is straight through and the 60e with a shift kit is known to be variably kinda clunky on the 2-3 at light throttle

I too have the transgo kit and did the 2-3 apply hole a little big in the sep plate. The clunk is probably just the clutches engaging quickly which is the reason I got the kit

What we have found is the timing between the band in second releasing and the third gear clutches applying, there is a slight bind in the shift. We've made the hole for the third gear firmness smaller and most of the clunk is gone. I've had this problem with my own car and I bought a new plate from GM just to try, and it seems to have worked fine. You can tune the trans for a firmer shift when you accelerate harder off the light with your laptop. Hope this helps.
