1. Preparation

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

2. Change Transmission Fluid and Filter

Tools Required: Socket set, fluid pump, torque wrench, pan, new transmission fluid, new filter, gasket.
Sub-steps:
1. Drain Fluid: Remove the transmission pan bolts and carefully lower the pan to drain the old fluid. Discard the old fluid responsibly.
2. Replace Filter: Remove the old transmission filter and install the new filter according to specifications.
3. Clean Pan: Clean the transmission pan and remove any old gasket material.
4. Install New Gasket: Place a new gasket on the pan and reinstall the pan with bolts to the specified torque (typically around 8 Nm).
5. Refill Transmission Fluid: Using a fluid pump, refill the transmission with the specified type of fluid (check owner's manual for correct specifications).

3. Inspect and Replace Transmission Mounts (if necessary)

Tools Required: Socket set, jack and jack stands.
Sub-steps:
1. Lift Vehicle: Safely lift the vehicle using a jack and secure it with jack stands.
2. Remove Old Mounts: Locate and remove the bolts securing the transmission mounts. Carefully lift the transmission slightly to access the mounts.
3. Install New Mounts: Position new mounts and secure them with bolts, torquing them to the manufacturer's specifications.

4. Reconnect Battery and Test
