Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical shorts.

2. Check Transmission Fluid

Remove the transmission dipstick and wipe it clean.
Insert the dipstick back in and remove it to check fluid level.
If low, add the recommended transmission fluid type (typically Honda ATF Z-1 or DW-1).
If fluid appears burnt or dirty, drain and replace the fluid.

3. Replace Transmission Filter

Tools Required: Socket set, wrench, fluid catch pan.
Remove the transmission pan bolts and carefully lower the pan.
Remove the old filter and replace it with a new one.
Clean the transmission pan and replace the gasket before reinstalling.

4. Inspect and Replace Transmission Mounts

Tools Required: Socket set, jack and jack stands.
Raise the vehicle safely using jack stands.
Inspect the transmission mounts for cracks or damage.
If damaged, remove the bolts securing the mounts and replace them with new ones.

5. Test Throttle Position Sensor (TPS)

Tools Required: Multimeter.
Locate the TPS on the throttle body.
Disconnect the sensor and test its resistance using a multimeter while moving the throttle.
Replace the TPS if readings are out of specifications.

6. Reconnect Battery and Test Drive

Reconnect the battery terminals.
Start the vehicle and conduct a test drive to check if the jerking issue is resolved.
