Solution

1. Preparation

Gather tools including a socket set, OBD-II scanner, multimeter, and a transmission fluid dipstick.
Ensure the vehicle is on a level surface and safely secured with wheel chocks.
Disconnect the battery to prevent electrical shorts during repairs.

2. Check and Replace Transmission Fluid

Fluid Level Check:
1. Remove the transmission dipstick and wipe it clean.
2. Reinsert the dipstick completely and pull it out to check the fluid level.
3. If low, add the recommended ATF (automatic transmission fluid) until it reaches the full mark.
Fluid Replacement:
1. Place a drain pan under the transmission pan.
2. Remove the transmission pan bolts using a socket wrench.
3. Carefully lower the pan to drain the old fluid.
4. Clean the pan and replace the filter if necessary.
5. Reinstall the pan with a new gasket (torque bolts to manufacturer specifications).
6. Refill with the recommended ATF through the dipstick tube.

3. Inspect and Repair Shift Linkage

Locate the shift linkage beneath the vehicle.
Inspect for any signs of wear, damage, or misalignment.
If damaged, replace the shift linkage components as necessary.
Adjust the linkage to ensure proper alignment with the transmission.

4. Test Brake Pedal Switch

Locate the brake pedal switch near the brake pedal arm.
Use a multimeter to check for continuity when the brake pedal is depressed.
If the switch is faulty, replace it with a new one.

5. TCM Inspection

Locate the transmission control module (usually near the transmission).
Check for loose connections or damaged wiring.
If the TCM is suspected to be faulty, consult the manufacturer for reprogramming or replacement.
