4L60E 2nd-3rd Clunk

[Shank]

I had a 4L60E built for my Jeep project. The swap is running well besides a clunk from 2nd to 3rd.

Trans has corvette servo and some sort of shift kit. It seems it shifts better up to two shifts from cold or when you reflash the tune. This has me somewhat thinking it could be TAPS (adaptive pressure). I?ve considered turning it off but really am not sure this is the right move.

2002 ECM, 1999 or 2000 4L60E (from a 5.3 application), 2002ish LR4.
