Technical Notes:

Installation Criticals:
• Fluid Fill: Must use genuine Honda HCF-2 CVT fluid exclusively and follow the factory overflow check procedure at operating temperature. Using ATF-Z1 or DW-1 will cause belt slippage and failure.
• TCM Programming: TCM memory reset and start clutch / pulley pressure feedback learning must be performed after installation using a Honda HDS scan tool.
• Torque Converter: Ensure full seating into the transmission oil pump drive before mating to the engine to prevent pump damage.
• Cooler Flushing: Flush the external transmission fluid warmer/cooler and lines thoroughly to remove metallic debris from the old unit.

Maintenance Tips:
• Use only genuine Honda HCF-2 CVT fluid.
• Perform CVT clutch calibration via OBD2 diagnostic scanner after installation.
• Replace transmission fluid and warmer filter at recommended intervals to prevent judder.
