Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Check and Replace Transmission Fluid

Tools Required: Funnel, transmission fluid pump, socket set.
Sub-steps:
1. Locate the transmission fluid dipstick and pull it out to check fluid level.
2. If low, use a funnel to add the correct type of transmission fluid (ATF WS for Toyota Tacoma).
3. If fluid is discolored or burnt, drain the old fluid by removing the transmission drain plug.
4. Replace with new fluid, ensuring the correct amount is filled as per manufacturer specifications.

3. Replace Transmission Filter

Tools Required: Socket set, wrench set, gasket scraper.
Sub-steps:
1. Remove the transmission pan by unscrewing the bolts and carefully scraping off the old gasket.
2. Take out the old transmission filter and replace it with a new one.
3. Reinstall the pan with a new gasket and torque the bolts to the manufacturer's specifications.

4. Inspect and Replace Transmission Mounts

Tools Required: Socket set, pry bar, jack stands.
Sub-steps:
1. Lift the vehicle securely using jack stands.
2. Locate the transmission mounts and inspect for cracks or excessive wear.
3. If damaged, remove the bolts securing the mounts and replace them with new mounts.
4. Torque the bolts to the recommended specifications.
