Is this the transmission or the Traction Control System? I'm not getting any CEL's or anything else. No matter what I do with the TCS button in the dash, the light in the switch doesn't come on.
I also don't see a fuse that is labeled for the TCS.
Anyone have any ideas??? Thanks for any help.

If I had to bet, I would say it's the pressure control solenoid. Do a search for "PCS" from a couple levels up (not just Oldsmobile forum)... there are some good posts (especially from FlatRater) about the notorious Delphi pressure control solenoid problem that ALL pre-2003 4T65E (and 4T40/45E) GM transmission suffer from.
