my EK with automatic Y8 is redlining at 3800rpm and i have to let off the gas pedal to shift gears. i have changed the shift control solenoid, and the torque convertor lock-up solenoid, car is in perfect time. can anyone help out here? i had a friend that had this same problem in his EG but we found out it was a ground wire that was loose, and that fixed all his problems. i have searched my car over and all wires are intact. anyone have any ideas?
