⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on electrical systems.
•Allow the vehicle to cool before working on the transmission, as it can become hot.

Symptoms

•Engine revs without vehicle movement
•Transmission slipping or harsh shifting
•Unusual noises from the transmission area
•Dashboard warning lights illuminated (e.g., transmission or check engine light)
•Fluid leaks under the vehicle, particularly transmission fluid
•Increased engine RPMs with no corresponding speed increase

Diagnostic Steps

1
Scan for error codes using an OBD-II scanner to identify any transmission-related faults.
2
Check the transmission fluid level and condition; look for burnt smell or dark coloration.
3
Inspect the transmission linkage and cables for misalignment or damage.
4
Test the operation of the throttle position sensor (TPS) using a multimeter.
5
Examine the drive axles for any visible signs of damage or disconnection.
6
Check for any leaks around the transmission pan and seals.
