my Toyota Corolla E210 (2019-2024) struggles to shift gears, what could be wrong?

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 avoid electrical shorts.

2. Check Transmission Fluid

• Tools Required: Transmission dipstick, funnel, clean rags.
• Check the transmission fluid level using the dipstick. If low, add the manufacturer's recommended transmission fluid.
• Inspect the fluid for discoloration or burnt smell; if contaminated, a fluid change will be necessary.

3. Replace Transmission Fluid (if needed)

• Tools Required: Socket set, drain pan, funnel, new transmission filter, new transmission fluid.
• Locate the transmission drain plug and remove it to drain old fluid into the drain pan.
• Replace the transmission filter according to manufacturer specifications.
• Reinstall the drain plug and fill the transmission with new fluid through the dipstick tube using a funnel, ensuring to use the correct type and amount specified in the owner's manual.

4. Inspect and Adjust Transmission Linkage

• Tools Required: Wrench set, screwdriver, adjustment tools.
• Inspect the linkage and cables connecting the gear shifter to the transmission. Tighten any loose connections.
• Adjust the linkage as necessary to ensure proper engagement of gears.

5. Reconnect Battery and Test

• Reconnect the battery terminals and ensure they are secure.
• Start the engine and test drive the vehicle to check if the gear shifting issue has been resolved.
