thunk when auto shifts to second, '99 denali

[SunlitComet]

sure you were not grabbing at the alignment screws. the removal pins would just pull up and out.

The two outside pins were threaded and backed out. The two inners were spun while pulling hoping to catch a thread. Must have broken an embedded nut in the plastic. I need to pull the grill and figure it out. Meanwhile installed a AC Delco TPS from Rock AUto. It arrived in a well used box and there are no stamping indicating its an ACDelco, likely a returned chinese part. The shifting did not improve.
