⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical systems.
•Allow the engine to cool before opening the transmission fluid system.

Symptoms

•Engine RPM increases without corresponding acceleration
•Delayed or harsh shifting between gears
•Unusual noises such as whining or grinding when changing gears
•Warning lights illuminated on the dashboard, such as the check engine light
•Burning smell from transmission fluid overheating
•Fluid leaks underneath the vehicle

Diagnostic Steps

1
Scan the vehicle's onboard computer using an OBD-II scanner to check for any error codes related to the transmission.
2
Inspect the transmission fluid level and condition; look for discoloration or burnt odor.
