Install New Fluid:
- Reattach the transmission pan with new gasket/sealant as needed.
- Refill the transmission with the appropriate type and amount of new fluid as specified in the owner's manual.
- Start the engine and cycle through the gears to circulate the new fluid.

3. Inspect and Replace Clutch (if applicable)

Remove Transmission:
- Safely lift the vehicle and support it on jack stands.
- Disconnect components linked to the transmission (e.g., driveshafts, electrical connectors).
- Remove the transmission mounting bolts and carefully lower the transmission.
Replace Clutch Kit:
- Remove the old clutch assembly (pressure plate and disc).
- Clean the flywheel surface and replace it if necessary.
- Install the new clutch kit, ensuring proper alignment and torque specifications are followed.
Reassemble Components:
