Clutch Apdapation Point (Kiss Point) Recommended Value Ranges (Please note that the range boundaries are not hard limits, the transmission may still work with values slightly out of bounds via self-adaptation):
| Clutch | Clutch Adaptation Point | Clutch Adaptation Point Pressure (in Bar) | |
| K1 | Upper Adaptation Point | In the range of 7.6 – 7.9 bar | |
| K1 | Lower Adaptation Point | In the range of 2.55 – 2.95 bar | |
| K2 | Upper Adaptation Point | In the range of 7.6 – 7.9 bar | |
| K2 | Lower Adaptation Point | In the range of 2.1 – 2.5 bar |
If you have value(s) outside of the ranges, check the clutch. If the Clutch (Friction Plates, Steel Plates, Pistons) are good, check hydraulic pressure sensors on the TCU.
