7.    Keep your engine properly tuned. A poor running engine can, at times, display symptoms similar to a transmission problem.

8.    Have other drivetrain components that may affect transmission function checked regularly. Driveshafts and their universal joints, driveaxles and their constant velocity joints, engine flywheels or flexplates, computer system and sensors, radiator and cooling lines to the transmission, engine and transmission mountings can cause problems.
