i also read on here FYI 4L60E common problems / failures | GM Truck Headquarters that the O2s and trans are on the same circut or something. i'm getting an O2 code too. i think "bank 1 sensor 3". could the trans code be related?
while i'm here, which one is bank 1 sensor 3? i had a stuck plug when i was removing the trans and just pulled the male ends out of the connector then out it back later. but there was two brow wire and not sure if it mattered where they went.

SOOOOO>>>> back to the trannys if it is the TCC do i need this kit here? TransGo Shift Kits 4L60E & 4L65E 1993-2006 (will not work on Hybrid) | Valve body kits | Bulkpart transmission parts
Difficulty?
