I did the 'gibson' tranny flush back in March about 10k miles ago. Last week got this CEL TCM-002f. The dash xmission indicator blanks out and the xmission sticks to a high gear on the fwy or a low gear in city/street driving. If I turn the engine off and back on, it clears the problem. There is no rhyme or reason when the CEL comes on....steady driving on the fwy...stop-n-go on the street....going up hill.

Thought a tranny flush would fix it again, but that didn't fix it, so I'm guessing I'm hosed. I was hoping it might be something fixable.

Not really cost effective to get a new tranny, so I may end up trying to trade it in.
