Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to ensure safety while working on the electrical components.

2. Check and Replace Transmission Fluid

Tools Required: Transmission fluid pump, funnel, drain pan.
Remove the transmission pan bolts and carefully lower the pan.
Drain the old transmission fluid into a drain pan.
Inspect the fluid condition; if it is burnt or contaminated, proceed with a full fluid change.
Replace the transmission filter if it is dirty or clogged.
Reinstall the transmission pan with a new gasket and torque the bolts to the manufacturer’s specifications (usually around 10-12 ft-lbs).
Refill with the appropriate type of transmission fluid (typically Toyota ATF WS) using a fluid pump and funnel.

3. Inspect and Replace Transmission Solenoids

Tools Required: Socket set, torque wrench, multimeter.
Remove the transmission pan (as previously outlined) to access the solenoids.
Disconnect the electrical connectors from the solenoids.
Use a multimeter to test the solenoids for resistance; replace any that are out of spec.
Install the new solenoids by reversing the removal steps and torque them to the manufacturer’s specifications.
Reinstall the transmission pan and refill with fluid.

4. Check for Mechanical Issues

If slipping persists, further disassembly of the transmission may be required.
Remove the transmission from the vehicle following the manufacturer’s service manual.
Inspect the clutch packs, gears, and bands for wear or damage.
Replace any worn components as necessary and reassemble the transmission.
