Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, fluid catch pan, screwdriver set, multimeter.
Ensure the vehicle is on a level surface and the engine is off.
Disconnect the battery to ensure safety while working on electrical components.

2. Check and Top Off Transmission Fluid

Locate the transmission dipstick or fill plug.
Remove the dipstick or plug and wipe clean.
Insert the dipstick back, remove, and check the fluid level; add the specified transmission fluid if low.
If fluid is burnt or contaminated, proceed to fluid replacement.

3. Replace Transmission Fluid (if needed)

Place a fluid catch pan under the transmission.
Remove the transmission pan bolts using a socket set and carefully lower the pan.
Discard the old gasket and clean the pan thoroughly.
Replace the transmission filter if applicable.
Install a new gasket and reattach the pan with proper torque specifications.
Refill the transmission with the correct type and amount of fluid.

4. Inspect and Repair Gear Selector Mechanism

Remove the center console cover to access the gear selector.
Inspect the linkage for any disconnections or damage.
If needed, adjust or replace the gear selector mechanism.
Reassemble the center console cover once repairs are complete.

5. Test the Transmission Control Module (TCM)

Using a multimeter, check the voltage and ground connections to the TCM.
If readings are out of specifications, repair or replace wiring as necessary.
If the TCM is faulty, replace with a compatible unit and reprogram as required.
