Solution

1. Preparation

Gather tools and parts. Ensure the vehicle is parked on a level surface and the engine is turned off.
Tools Required: Jack and jack stands, socket set, OBD-II scanner, transmission fluid.

2. Check and Replace Transmission Fluid

Locate the transmission dipstick, remove it, and wipe it clean.
Reinsert the dipstick and check the fluid level; it should be within the recommended range.
If low, add the appropriate type of transmission fluid as specified in the owner's manual.
If the fluid is dark or smells burnt, drain and replace the fluid.
- Sub-steps:
  - Raise the vehicle using a jack and secure it with jack stands.
  - Place a drain pan under the transmission pan, remove the pan bolts, and allow old fluid to drain.
  - Replace the transmission filter if applicable, then reinstall the pan with new gasket and torque bolts to specifications (typically around 8-10 ft-lbs).
  - Refill with new transmission fluid as per the owner's manual.

3. Inspect and Adjust Transmission Linkage

Visually inspect the linkage for any visible damage or misalignment.
If necessary, adjust the linkage according to manufacturer's specifications to ensure proper engagement of gears.

4. Test Brake Switch

Locate the brake switch and test its functionality.
If defective, replace the brake switch to restore proper signals required for shifting.

5. Electrical Check

Use a multimeter to check the battery voltage; ensure it is at least 12.6 volts.
Inspect battery terminals for corrosion and clean if necessary.
