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 pan to avoid burns from hot fluid.

Symptoms

•Transmission warning light illuminated on the dashboard
•Engine revs without corresponding vehicle movement
•Unresponsive gear selector
•Delay in engaging gears after moving the selector
•Unusual noises from the transmission area
•Fluid leakage under the vehicle

Diagnostic Steps

1
Scan the vehicle's onboard diagnostics (OBD-II) for any error codes related to the transmission.
2
Check the transmission fluid level and condition using the dipstick.
3
Inspect for any visible leaks around the transmission and under the vehicle.
4
Test the transmission range sensor and gear selector mechanism for proper operation.
5
Examine the battery voltage; low voltage can affect electronic shift controls.
6
Inspect the transmission control module (TCM) connections for corrosion or loose wiring.

Solution
