Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical shorts.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Remove the transmission dipstick and check fluid level; add fluid if low.
2. If the fluid is burnt or contaminated, drain the old fluid using a fluid pump or drain plug.
3. Replace the transmission filter if applicable; remove the old filter and install a new one.
4. Refill the transmission with the appropriate type and amount of fluid (Toyota Type T-IV or equivalent).
5. Start the engine, let it warm up, and cycle through the gears while monitoring the fluid level, adding if necessary.

3. Inspect and Repair Transmission Control Module

Sub-steps:
1. Locate the TCM, usually found near the transmission or under the dashboard.
2. Disconnect the wiring harness and inspect for corrosion or damage.
3. Reconnect and test the TCM using a multimeter, checking for proper voltage and ground.
4. If faulty, replace the TCM with a compatible unit, ensuring proper programming if necessary.

4. Check Shift Linkage

Sub-steps:
1. Inspect the shift linkage for any misalignment or loose connections.
2. Adjust or tighten the linkage as required.
3. Lubricate any pivot points to ensure smooth operation.

5. Replace Transmission Mounts (if necessary)

Sub-steps:
1. Lift the vehicle and secure it with jack stands.
2. Remove the bolts securing the transmission mounts to the frame and transmission.
3. Replace the old mounts with new ones, ensuring proper alignment.
4. Torque the bolts to the manufacturer's specifications.
