why does my Toyota Highlander Third Generation (2014-2019) have a delay when shifting?

Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is on a level surface and safely supported.
• Disconnect the battery to prevent electrical shorts.

2. Check Transmission Fluid

• Tools Required: Transmission dipstick, funnel, clean rags.
• Remove the transmission dipstick and wipe it clean.
• Insert the dipstick back into the tube and remove it again to check the fluid level.
• If low, add the manufacturer's recommended transmission fluid to the correct level.
• Inspect the fluid's color; if dark or burnt, a fluid change may be necessary.

3. Replace Transmission Filter

• Tools Required: Socket set, wrench set, transmission filter kit, torque wrench, catch pan.
• Remove the transmission pan using a socket and wrench, allowing fluid to drain into the catch pan.
• Replace the old transmission filter with a new one, ensuring the new filter is seated correctly.
• Clean the pan and replace the gasket if necessary.
• Reinstall the transmission pan and torque the bolts to the manufacturer's specifications.

4. Inspect and Adjust Linkage

• Tools Required: Socket set, pliers.
• Inspect the transmission linkage for damage or misalignment.
• Adjust the linkage as needed to ensure proper engagement of the gears.

5. Reconnect Battery and Test

• Reconnect the battery terminals securely.
• Start the vehicle and allow it to warm up to operating temperature.
• Test drive the vehicle to check for improvements in shifting performance.
