Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick and remove it.
2. Check the fluid level; add ATF (Toyota Type T-IV) if low.
3. If the fluid is dark or has a burnt smell, proceed to drain and replace.
4. Place a drain pan under the transmission pan and remove the pan bolts.
5. Drain the old fluid and clean the pan.
6. Replace the transmission filter if applicable.
7. Reinstall the pan with new gasket and torque bolts to manufacturer specifications.
8. Refill the transmission with new fluid using the dipstick tube.

3. Inspect and Repair Transmission Components

Sub-steps:
1. Remove the transmission pan to access internal components.
2. Inspect the clutches and bands for wear or damage.
3. Replace any worn components (clutches, bands, seals).
4. Check solenoids for operation; replace if faulty.
5. Reassemble the transmission pan and refill fluid as mentioned.

4. Reprogram TCM (if necessary)

Sub-steps:
1. Connect the OBD-II scanner to the vehicle's diagnostic port.
2. Follow the manufacturer's instructions to reprogram the TCM if any issues were detected.
3. Clear any fault codes and perform a drive cycle to ensure proper function.
