Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery terminals to prevent electrical shorts.

2. Transmission Fluid Change

a. Drain the Old Fluid:
- Locate the transmission drain plug and remove it using a socket set.
- Allow the fluid to completely drain into a suitable container.
b. Replace the Transmission Filter:
- Remove the transmission pan by unscrewing the bolts with a socket set.
- Replace the old filter with a new filter.
c. Reinstall the Pan:
- Clean the transmission pan and apply a new gasket or RTV sealant.
- Reattach the pan and torque the bolts to the manufacturer's specifications (typically around 8-10 Nm).
d. Add New Fluid:
- Using a funnel, add new transmission fluid (check the owner's manual for the specific type and capacity).
- Start the engine and let it run for a few minutes, then check the fluid level and top off as necessary.

3. Transmission Control Module (TCM) Reset

a. Reconnect the Battery:
- Reattach the battery terminals securely.
b. Reset the TCM:
- Use an OBD-II scanner to clear any fault codes present in the TCM.
- Perform a reset of the TCM to reprogram it to learn the vehicle's driving habits anew.

4. Inspect and Replace Engine and Transmission Mounts

a. Visual Inspection:
- Check all mounts for cracks, excessive wear, or separation.
b. Replacement:
- If any mounts are damaged, replace them with OEM parts.
- Ensure proper torque specifications when securing new mounts.
