Thank you very much for the informative post. You are clearly an asset here and you got the problem right on the money. Before I saw your post, I was googling my codes and came up with a post on a Lumina board. A guy had the same problem as me and the same three error codes. Someone posted back that didn't have a trans problem, he had a blown fuse.
Went right to my fuse box and found that the 15A minifuse, middle right was blown. Couldn't read the box cover too well but looked like it said TCC. If so, that makes a lot of sense - no power to the torque converter to lock up. Put in a 15A fuse, cleared the codes, drove it for a half hour and it's fine. Dives great and no codes.
Seems like that was the problem. But I'm wondering - why did the fuse blow in the first place?
Any ideas.
Thanks...Boatman

Glad to hear that fixed your problem! The fuse could have blown for a number of reasons but likely wasnt from a bad solenoid in the trans. One of the wires that comes off of that fuse runs to a switch on the brake pedal and then back out to the TCC solenoid to dissable power to it during braking so the engine wont stall. More often than not its a bad switch or wiring problem that would blow the fuse. If it happens again then maybe you will have something concrete to search for but intermittant problems can make you chase your tail for a long time.
