Abstract

Within of the method for improving the shifting quality at the start of the commissioning of a new automatic transmission or an automated transmission of a motor vehicle, a filling pressure adaptation is carried out by individual gearshifts. At least one adaptation counter is monitored, which indicates the number of the carried out filling pressure adaptations of at least one shifting element with one individual gearshift from the commissioning of the new automatic transmission or automated transmission. As long as the value of a specified number of monitored adaptation counters falls below a specified threshold value, no D-R and R-D reversing operations are permitted by the transmission control.
