https://docs.emtronaustralia.com.au/transmission-control/tuning/clutch-model/index.htmlThe TCM will use the clutch geometry model to calculate the torque capacity of each clutch. These settings are critical to correct transmission behavior. Clutch Geometry Clutch geometry is taken into account in two directions: Calculating how much pressure to apply to hold a given torque. Calculating how much torque a given pressure can hold. Plate Count The number of friction plates in the clutch assembly. Aftermarket clutch kits often have increased plate counts, make sure to enter the correct number here.Hugoen-us
