why does my Toyota RAV4’s transmission make a grinding noise when shifting

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and set the parking brake.
• Disconnect the battery to prevent electrical shorts.

2. Check Transmission Fluid

• Remove the transmission dipstick and wipe it clean.
• Reinsert it and check the fluid level; top off with the manufacturer-recommended fluid if low.
• Inspect the fluid for contamination or burnt smell; if contaminated, a fluid change is required.

3. Inspect Gear Linkage

• Remove the protective covers to access the gear linkage.
• Check for worn or damaged bushings and connections.
• Adjust or replace any misaligned or defective components as necessary.

4. Examine Clutch Assembly (if applicable)

• Remove the transmission from the vehicle following manufacturer guidelines.
• Inspect the clutch disc, pressure plate, and release bearing for wear or damage.
• Replace any worn components with OEM parts, ensuring proper alignment during reassembly.

5. Transmission Synchronizers Check

• If grinding persists, open the transmission to inspect the synchronizers.
• Replace any worn or damaged synchronizer rings.
• Reassemble the transmission with OEM seals and gaskets.
