Before putting new connector to tps, tc would occassionally (two or three times a day)kick in and out. New scenerio: Will not shift at 45mph like it used to. I have to step on it and drive rpms to about 2200 to 2300. If I do this, everything kicks in at about 50 to 55. If I drive 70mph, everything functions normal. As soon as I slow down below 60, not only does tc kick out, trans down shifts a gear. Driving 40 to 55, I turn 2200 to 2400 rpms and let her roar. I have about given up. By the way, I unplugged two other connectors to work on tps connector. One connector mounted to a solid base just to the right and little low of were you add power steering fluid. This connector was extremely oily on the inside. Does anyone know what this is connected to and could it be the problem. Thank you for taking the time to read my feeble attempt at writing a novel. Confused in San Antonio. By the way, anybody want to buy a truck?

I have a similar problem. The OD kicks in and out as I run my commute. Sometimes it only raises the RPM about 50-150 RPM for a few seconds and then back to normal, sometimes it keeps kicking in and out of OD. I take off the OD and the engine seems to run OK. Dealer could not find any errors, etc. I think it may be an errant electrical issue but not sure yet. Some days its OK some its a real pain.
