2. Drain Old Transmission Fluid

Position the drain pan underneath the transmission pan.
Remove the transmission pan bolts using a socket wrench.
Carefully lower the pan and allow the old fluid to drain completely into the pan.
Inspect the transmission filter and gasket for damage.

3. Replace Transmission Filter (if applicable)

If your Tacoma has a replaceable filter, remove the old filter.
Install the new filter according to the manufacturer's specifications.

4. Reinstall Transmission Pan

Clean the transmission pan and the mating surface on the transmission.
Place a new gasket on the pan or apply gasket maker if required.
Reinstall the transmission pan and torque the bolts to the manufacturer’s specifications (typically around 8-12 ft-lbs, but check the manual).

5. Add New Transmission Fluid

Using the funnel, add the new transmission fluid through the dipstick tube or designated fill plug according to the specifications in the owner's manual.
Ensure the correct type and amount of fluid is used (typically around 4-5 quarts, but verify).

6. Check Fluid Level

Start the engine and allow it to warm up.
With the vehicle in park, check the fluid level with the dipstick (if equipped). Add fluid as necessary to reach the proper level.
