-
-
-
-
Function: Aisin AW-designed 8-speed transverse automatic (TF-80SC lineage) for FWD/AWD platforms (torque capacity 450Nm).
Key Features:
-
Shift Logic: BMW/Mini-specific programming with sport/eco modes
-
Start-Stop Ready: Reinforced auxiliary pump maintains hydraulic pressure
-
Modular Construction: Separate mechatronics unit (simplifies repairs)
Common Failures:
-
Solenoid Wear: Particularly shift solenoids 3/5 (P17D1/P17D4)
-
Converter Clutch Shudder: Lockup judder from worn apply piston (P0741)
-
Case Leaks: Main seal failure near differential output
Critical Service Notes:
-
Fluid: Only BMW/Mini ATF-3 (5.5L capacity)
-
Adaptations Reset: Required after fluid service (ISTA/P required)
-
Thermal Management: Monitor oil temp – sustained >120°C degrades fluid
Pro Tip: Check mechatronic sleeve seals during fluid changes – seepage causes erratic shifts.
