Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Check and Refill Transmission Fluid

Locate the transmission dipstick and remove it.
Wipe it clean, reinsert, and check the fluid level.
If low, add the manufacturer-recommended transmission fluid until it reaches the proper level (consult owner's manual for specifications).
Start the engine and cycle through the gears to circulate the fluid, then check the level again.

3. Inspect Gear Shift Linkage

Remove the center console cover to access the gear shift mechanism.
Visually inspect the linkage for any signs of wear, damage, or misalignment.
Adjust or replace any damaged components as necessary.

4. Test Brake Pedal Switch

Locate the brake pedal switch, usually mounted above the brake pedal.
Use a multimeter to test the switch for continuity when the pedal is pressed.
If defective, replace the brake pedal switch.

5. Check Transmission Control Module (TCM)

Inspect the TCM connections for corrosion or damage.
If necessary, reprogram or replace the TCM following manufacturer procedures.

6. Reassemble and Reconnect

Reassemble any parts removed during the inspection.
Reconnect the negative battery terminal.
Ensure all tools are removed from the engine bay.
