Installation & Maintenance Notes

• Fluid Service (Critical): Upon installation, it is mandatory to flush the system and refill with genuine Honda ATF-DW1 (or high-spec compatible fluid). Fresh fluid is the most vital factor in preserving the longevity of the transmission's internal valve body and clutch packs.

• TCM Adaptation: After installation, if you notice erratic shifting during the first few miles, allow the Transmission Control Module (TCM) time to "re-learn" the shift points. If issues persist, perform a TCM reset using an OBD-II scanner.

• Cooling: To maximize the lifespan of this replacement unit, verify your existing transmission fluid cooler lines are free of debris. An auxiliary cooler is highly recommended if your vehicle is used for frequent short-trip city driving, which is known to heat-soak this transmission series.

• Safety First: Transmission replacement requires professional engine support and subframe clearance. Always perform this work on a professional lift using appropriate safety stands.
