Speedometer doesn't work. Have to manually shift only after car is started. After it gets to 5th gear, it drops to 4th & back.
What is your question?
Car only drops from 5th to 4th after car...engine/tranny...are warmed up. After the initial manually shifting after starting the car, it shifts on it's own after that

Hello,
This may all be the result of a failed vehicle speed sensor or transmission output sensor. If the vehicle does not know how fast it is going, it can't tell when to shift.
