I paid $330 or so for my PCM from Black Bear, so if you could get it for less than $100 I would jump on it, but I'd send it back into Black Bear so they could adjust it for your truck if possible
I agree with
@df2x4, make sure it's the correct year pin out for your truck, 96-97 have an extra plug in the middle, 98+ has the 4.
I've got a 4L80E in my 96 K2500, but I still left TQM alone and had them leave shift firmness alone. I'm debating on when I retune having it turned back some, but I know my trans can take thw abuse. A 4L60E will not.
