Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, fluid catch pan.
Safety Warnings: Disconnect the battery before working on electrical systems. Allow the engine to cool before opening the transmission fluid reservoir.
Gather all necessary tools and parts for the repair.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Park the vehicle on a level surface and set the parking brake.
2. Remove the transmission dipstick and check the fluid level.
3. If the fluid is low, add the correct type of transmission fluid (Toyota Type T-IV).
4. If the fluid is dark or smells burnt, proceed to drain and replace the fluid.
5. To drain, remove the transmission pan bolts using a socket set.
6. Carefully lower the transmission pan, allowing fluid to drain into a catch pan.
7. Replace the transmission filter if applicable.
8. Clean the pan and apply new gasket material or replace the gasket.
9. Reinstall the pan and torque bolts to specifications (typically 8-10 ft-lbs).
10. Refill the transmission with the appropriate amount of new fluid through the dipstick tube.

3. Inspect and Replace Damaged Components

Sub-steps:
1. Inspect the transmission mount and replace it if worn or damaged.
2. Check the transmission cooler and lines for leaks; replace any damaged sections.
3. If wiring or connectors are corroded, clean or replace them as necessary.
4. If error codes indicate a faulty transmission control module, replace it following manufacturer guidelines.
