Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Ensure the vehicle is on a level surface, and raise it using jack stands if necessary.

2. Change CVT Fluid

Drain the CVT Fluid:
- Locate the drain plug on the CVT pan and remove it using a socket wrench.
- Allow the fluid to fully drain into a suitable container.
Replace the Transmission Filter:
- Remove the CVT pan by unscrewing the bolts using a socket set.
- Carefully detach the pan, and replace the filter with a new one.
Replace the Gasket:
- Clean the mating surfaces on the transmission and pan.
- Install a new gasket onto the pan.
Refill CVT Fluid:
- Reattach the CVT pan and tighten the bolts to the manufacturer's specified torque.
- Using a funnel, refill the CVT with the recommended fluid type (usually Toyota CVT Fluid).
- Start the engine and let it idle, then shift through all gear positions to circulate the fluid.

3. Test and Replace CVT Solenoids (if needed)

If diagnostic steps indicated solenoid issues:
- Disconnect electrical connectors from the solenoids.
- Remove the solenoids from the valve body by unscrewing them.
- Install new solenoids and reconnect electrical connectors.
