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 radiator or working on the transmission.

Symptoms

•Delay in engagement when shifting from park to drive or reverse
•Increased engine RPMs before the vehicle starts moving
•Slipping sensation during acceleration
•Harsh or jerky shifts at low speeds
•Fluid leaks under the vehicle
•Check engine light may be illuminated

Diagnostic Steps

1
Scan for error codes using an OBD-II scanner to identify any transmission-related trouble codes.
2
Check the transmission fluid level and condition, looking for signs of contamination or burning.
3
Inspect the transmission fluid for proper color and smell; it should be a bright red and not have a burnt odor.
4
Conduct a visual inspection of the transmission and surrounding components for leaks or damage.
5
Test the transmission solenoids for proper function using a multimeter.
6
Verify the operation of the throttle position sensor (TPS) and other related electronic components.

Solution
