my Honda Accord transmission jerks between gears what's causing it

Solution

1. Preparation

• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the battery to prevent any electrical shorts during the repair.
• Gather tools and parts required for the repair.

2. Check and Change Transmission Fluid

• Tools Required: Socket set, funnel, drain pan
• Remove the transmission drain plug and allow fluid to drain completely into the pan.
• Replace the drain plug and torque to manufacturer specifications.
• Use a funnel to add new transmission fluid through the dipstick tube, ensuring it meets the manufacturer’s specifications.
• Check the fluid level with the dipstick, adding more fluid as necessary.

3. Inspect and Replace Transmission Filter (if applicable)

• Tools Required: Socket set, screwdrivers, transmission filter kit
• Remove the transmission pan by unscrewing the retaining bolts. Be careful of any remaining fluid.
• Remove the old transmission filter and replace it with a new one from the filter kit.
• Clean the pan and mating surfaces to ensure a good seal, then reattach the pan using a new gasket.

4. Inspect Transmission Control Module (TCM)

• Tools Required: Multimeter, screwdriver
• Disconnect the TCM harness and visually inspect for damage or corrosion.
• Use a multimeter to check the TCM power and signal outputs; replace if faulty.

5. Test Drive and Monitor Performance

• Reconnect the battery and start the vehicle.
• Perform a test drive to monitor the transmission shifting behavior.
• Ensure that the jerking issue has been resolved and that the transmission operates smoothly.
