Solution

1. Preparation

Ensure the vehicle is parked on a level surface and set the parking brake.
Gather tools and parts needed for the repair.

2. Check Transmission Fluid

Tools Required: Transmission fluid dipstick, funnel, clean rags.
Sub-steps:
1. With the engine running, pull out the transmission fluid dipstick.
2. Wipe it clean and reinsert it, then check the level and condition of the fluid.
3. If fluid is low, top it up with the manufacturer-recommended transmission fluid (typically Toyota ATF WS).
4. If the fluid is burnt or contaminated, a transmission fluid change is necessary.

3. Inspect and Adjust Transmission Linkage

Tools Required: Socket set, adjustable wrench.
Sub-steps:
1. Locate the transmission linkage under the vehicle.
2. Inspect for any signs of wear or damage.
3. If misaligned, adjust the linkage according to the service manual specifications.
4. Tighten any loose bolts to the specified torque.

4. Replace Brake Pedal Position Switch (if necessary)

Tools Required: Screwdriver set, new brake pedal position switch.
Sub-steps:
1. Disconnect the battery to ensure safety.
2. Locate the brake pedal position switch on the brake assembly.
3. Remove the old switch by disconnecting the electrical connector and unscrewing it.
4. Install the new switch and reconnect the electrical connector.
5. Reconnect the battery.

5. Test Drive and Recheck Fluid

Sub-steps:
1. After completing the repairs, start the vehicle and let it warm up.
2. Shift through all gears to ensure smooth operation.
3. Check the transmission fluid level again and top up if necessary.
