Estimated Time

2-4 hours

⚠️ 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 reservoir.

Symptoms

•Transmission warning light illuminated
•Gear shifter feels stuck or unresponsive
•No engagement or movement when shifting
•Unusual noises from the transmission area
•Fluid leaks under the vehicle
•Check engine light illuminated

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; ensure it is at the correct level and not burnt or contaminated.
3
Inspect the gear shifter linkage for binding or damage that may prevent proper shifting.
4
Test the brake switch; ensure it is functioning correctly as it can affect shifting in automatic transmissions.
