Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Check and Replace Transmission Fluid

Step 1: Remove the transmission dipstick and wipe it clean.
Step 2: Reinsert the dipstick and remove it again to check the fluid level. If low, proceed to add fluid.
Step 3: If the fluid is dirty or burnt, drain the transmission fluid by removing the drain plug.
Step 4: Replace the drain plug and refill with the manufacturer-recommended transmission fluid (typically Toyota Type T-IV or WS).
Tools Required: Socket set, funnel, new transmission fluid.

3. Inspect and Replace Transmission Filter

Step 1: Remove the transmission pan by loosening the bolts with a socket set.
Step 2: Allow any remaining fluid to drain from the pan.
Step 3: Remove the old transmission filter and replace it with a new one.
Step 4: Clean the transmission pan and install it back with a new gasket, torquing the bolts to the manufacturer's specifications.
Tools Required: Socket set, new gasket, new transmission filter.

4. Check and Replace Transmission Solenoids (if necessary)

Step 1: Remove the transmission cover to access the solenoids.
Step 2: Disconnect the electrical connectors from the solenoids.
Step 3: Unbolt the solenoids and replace them with new units.
Step 4: Reconnect the electrical connectors and reassemble the transmission cover.
Tools Required: Torque wrench, socket set, replacement solenoids.

5. Reconnect Battery and Test Drive

Reconnect the negative battery terminal.
Start the engine and check for leaks.
Test drive the vehicle to ensure the transmission is functioning properly without slipping.
