Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely lifted.
Disconnect the battery to ensure safety while working on electrical components.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Remove the transmission dipstick and wipe it clean.
2. Insert the dipstick back and remove it again to check the fluid level.
3. If low, add the manufacturer-recommended transmission fluid (Toyota Type T-IV or WS).
4. If the fluid is burnt or contaminated, proceed to change the fluid.
5. Drain the old transmission fluid by removing the drain plug or pan.
6. Replace the transmission filter if applicable, and reassemble the pan with a new gasket.
7. Refill with new transmission fluid, checking the level with the dipstick.

3. Inspect and Replace Transmission Mounts

Sub-steps:
1. Locate the transmission mounts (typically found where the transmission connects to the chassis).
2. Use a jack to support the transmission while removing the mounts.
3. Inspect the mounts for cracks or excessive wear.
4. Replace any damaged mounts with OEM parts and torque to manufacturer specifications.

4. Test and Replace Solenoids if Necessary

Sub-steps:
1. Locate the transmission control module (TCM) and solenoids.
2. Use a multimeter to test the resistance of the solenoids according to manufacturer specifications.
3. If any solenoids are out of range, remove and replace them with new units.
4. Reassemble the transmission components and reconnect the TCM.
