why does my Toyota Highlander shudder when I accelerate from a stop

Solution

1. Preparation

• Gather tools and safety equipment.
• Ensure the vehicle is on a flat surface and engage the parking brake.
• Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Transmission Fluid

• Tools Required: Socket set, fluid pump, transmission fluid.
• Remove the transmission pan using a socket set.
• Drain old transmission fluid into a suitable container.
• Inspect the transmission filter; replace if necessary.
• Reinstall the transmission pan with a new gasket and torque it to manufacturer specifications.
• Refill with the appropriate transmission fluid through the dipstick tube using a fluid pump.

3. Replace Motor and Transmission Mounts (if damaged)

• Tools Required: Socket set, pry bar, torque wrench.
• Lift the vehicle using a jack and secure it with jack stands.
• Remove the bolts securing the motor and transmission mounts.
• Use a pry bar to carefully lift the engine/transmission to relieve pressure on the mounts.
• Replace the mounts with new ones and ensure proper alignment.
• Torque the bolts to the manufacturer’s specifications.

4. Inspect and Replace Driveshaft or CV Joints (if necessary)

• Tools Required: Jack stands, socket set, grease.
• Lift the vehicle to access the driveshaft and CV joints.
• Inspect for any signs of wear, such as torn boots or play in the joints.
• If damaged, remove the driveshaft or CV joint assembly by unbolting it from the differential and transmission.
• Replace with new components and ensure proper greasing where applicable.
