my Toyota RAV4 Fifth Generation (2019-present) transmission slips during acceleration

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the battery to prevent any electrical issues.

2. Check Transmission Fluid

• Tools Required: Transmission dipstick, funnel.
• Remove the transmission dipstick and check the fluid level; add fluid if low.
• If fluid is dark or has a burnt smell, proceed to replace the transmission fluid.

3. Replace Transmission Fluid

• Tools Required: Socket set, drain pan, funnel, new transmission fluid (consult owner’s manual for specifications).
• Place a drain pan under the transmission pan and remove the drain plug or pan bolts to let old fluid drain completely.
• Clean the transmission pan and replace the filter if applicable.
• Reinstall the pan or plug and refill with new transmission fluid through the dipstick tube.

4. Inspect and Replace Transmission Solenoids

• Tools Required: Socket set, multimeter.
• Locate the transmission solenoids (usually found on the transmission valve body).
• Disconnect the wiring harness and remove the solenoid(s) using a socket set.
• Test each solenoid with a multimeter; replace any that are faulty.
• Reinstall the new solenoid(s) and reconnect the wiring harness.

5. Verify Transmission Mounts

• Tools Required: Jack stands, socket set.
• Safely lift the vehicle and inspect the transmission mounts for cracks or excessive wear.
• Replace any damaged mounts with new ones.
