Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is on a level surface and safely secured with jack stands.
Disconnect the battery to prevent electrical shorts.

2. Address Fluid Leaks

Sub-steps:
1. Identify the source of the leak (pan, seals, or gaskets).
2. If leaking from the pan, remove the bolts using a socket set and carefully lower the pan.
3. Clean the mating surfaces with a solvent to remove old gasket material.
4. Replace the gasket and reattach the pan, tightening bolts to the manufacturer’s torque specifications (typically around 10-15 ft-lbs).

3. Replace Transmission Fluid

Sub-steps:
1. Drain the old transmission fluid by removing the drain plug (if equipped) or pan.
2. Replace the filter (if applicable) by removing the old filter and installing the new one.
3. Refill the transmission with the manufacturer-recommended fluid (typically Toyota ATF WS) through the dipstick tube.
4. Start the engine and cycle through the gears for a few minutes to circulate the fluid.

4. Repair or Replace Solenoids

Sub-steps:
1. Remove any necessary components to access the transmission solenoids.
2. Disconnect the electrical connectors from the solenoids.
3. Remove the solenoids and inspect them for wear or damage.
4. Replace with new solenoids if faulty and reconnect electrical connectors.
