my Toyota RAV4 won't shift gears smoothly what could be wrong

Solution

1. Preparation

• Gather necessary tools and parts.
• Park the vehicle on a level surface, engage the parking brake, and disconnect the battery to ensure safety.

2. Check Transmission Fluid

• Locate the transmission dipstick (if equipped).
• Remove the dipstick, wipe it clean, and reinsert it to check the fluid level.
• If low, add the correct type of transmission fluid as specified in the owner's manual.

3. Inspect and Replace Transmission Filter

• Tools Required: Socket set, screwdriver, transmission fluid pump.
• Remove the transmission pan by loosening the bolts; allow fluid to drain into a catch pan.
• Take out the old transmission filter and replace it with a new one.
• Reinstall the transmission pan with a new gasket and torque the bolts to the manufacturer's specifications.

4. Adjust Transmission Linkage

• Inspect the linkage for any signs of wear or misalignment.
• If misaligned, adjust the transmission linkage according to the vehicle service manual.

5. Replace Faulty Solenoids

• If solenoids are found to be faulty during testing, remove the transmission pan again following the steps in section 3.
• Disconnect the electrical connectors from the solenoids and remove them from the valve body.
• Install new solenoids and reconnect the electrical connectors.

6. Refill Transmission Fluid

• Use a funnel to refill the transmission with the correct type and amount of fluid.
• Start the engine and cycle through the gears while checking for smooth shifting.
