Solution

1. Preparation

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

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick, remove it, and clean it with a lint-free cloth.
2. Insert the dipstick back and remove it again to check the fluid level.
3. If the fluid is low, add the recommended type of transmission fluid (Toyota ATF WS).
4. If the fluid is dirty or has a burnt smell, drain the transmission fluid.
5. Replace with new fluid and check for leaks.

3. Inspect and Adjust Transmission Linkage

Sub-steps:
1. Locate the transmission linkage and examine it for any wear or misalignment.
2. Adjust the linkage according to the manufacturer specifications, ensuring it engages properly.
3. Tighten any loose bolts to secure the linkage.

4. Test and Replace Transmission Solenoids

Sub-steps:
1. Locate the transmission solenoids in the transmission assembly.
2. Use a multimeter to test each solenoid for resistance; compare results with specifications in the service manual.
3. If any solenoid is faulty, remove it and replace it with a new one, ensuring proper installation.

5. Check and Replace Engine/Transmission Mounts

Sub-steps:
1. Inspect the engine and transmission mounts for cracks or significant wear.
2. If damaged, support the transmission and engine using a jack.
3. Remove the mounting bolts and replace the mounts with new OEM units, torquing them to specifications.
