Technical Notes:

Installation Criticals:
• Fluid Fill: Must follow the specific overflow check temperature procedure (35°C - 45°C) using Toyota Techstream. Over/under-filling causes launch gear shock or failure.
• TCM Programming: Solenoid compensation code registration, G-sensor initialization, and clutch pressure learning are required after installation.
• Torque Converter: Ensure full seating ("three clicks") before mating to the engine block to prevent pump damage.
• Cooler Flushing: Flush the external transmission fluid warmer/cooler and lines thoroughly to remove debris from the old unit.

Maintenance Tips:
• Use only genuine Toyota CVT Fluid FE.
• Perform TCM adaptation reset and learning via OBD2 scanner after installation.
• Monitor transmission temperature during AWD operation to prevent overheating.
