⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical systems.
•Allow engine to cool before working on the transmission to avoid burns.

Symptoms

•Slipping or delayed engagement when shifting from park to drive or reverse
•Unusual engine RPM fluctuations while driving
•Overheating transmission fluid
•Shuddering or vibration during acceleration
•Poor fuel economy
•Check engine light illuminated with relevant trouble codes

Diagnostic Steps

1
Scan for error codes using an OBD-II scanner to identify any transmission-related trouble codes.
2
Perform a visual inspection of the transmission fluid for clarity and proper level.
