I was having a lot of trouble with the transmission shifting, and was thinking that it was the shift modulator. I did a hard ECU reset jumpering the + and - cables.
The shift patterns are all good now, but the engine vibrates, & no power in passing gear?
What is your question?
At first I thought, Shift Modulator, but the reset cleared all of that up once I drove the car to allow the ECU to learn the shift patterns, and idle speeds.
Now it is just the engine vibrates hard at an idle. It runs really good, and it shifts up, and down. Kicks into passing gear right on time, but has very little power.
