Installation Guide

1. Preparation: Warm the vehicle’s engine to operating temperature. This ensures the hydraulic fluid is at its optimal viscosity.
2. Drain Fluid: Locate the transmission drain plug and remove it to allow fluid to escape. Collect the drained fluid in a suitable container.
3. Remove Old Filter: Unscrew the existing filter housing. Carefully detach the old filter, taking note of any gasket or seal that may need replacement.
4. Install New Filter: Place the new filter into the housing, aligning it with the flow direction indicated by the arrow on the filter body.
5. Seal and Tighten: Apply the supplied gasket, then tighten the housing bolts to the manufacturer’s torque specification.
6. Refill Fluid: Refill the transmission with the recommended hydraulic fluid type and volume.
7. Check for Leaks: Start the engine and observe the filter area for any signs of leakage. Tighten bolts if necessary.
8. Test Drive: Conduct a short test drive to ensure smooth gear shifts and no abnormal noises.
