I recently had my trans rebuilt but even MORE recently, my "check engine" light is always on and the trans goes in to "limp home" mode. For example, if I'm going 60 and the system is working properly, the tach is about 1800-1900. When I accelerate slowly, so the clutch doesn't release, the tach goes up slowly. When there is a problem, and I accelerate slowly, the clutch releases and the tach goes up quickly. When I slow down, it goes into that "limp" mode and speeds up the engine, like it's locked in 2 gear. But sometimes, I can drive for a hundred miles and it does not do any of the above, except for the "check engine" light being on. I know I should take it to a shop but if anyone has any ideas of a way to massage it--I'm 1000 miles from home.
TIA John
