⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical components.
•Allow the engine to cool before opening the transmission or working on related components.

Symptoms

•Jerking or harsh shifting between gears
•Delayed engagement when shifting from park to drive/reverse
•Unusual noises during shifting (clunking or grinding)
•Check engine light illuminated
•Increased RPMs without corresponding acceleration

Diagnostic Steps

1
Scan the vehicle for error codes using an OBD-II scanner to identify any transmission-related fault codes.
2
