    • The invention relates to a process for the adaptive correction of the shifting quality of an automatic transmission which is coupled to an engine and in which correcting elements acting on the pressure or oil throughput bring friction elements into engagement in the form of clutches or brake bands to carry out shifting processes, the line pressure impinged on by the correcting elements being registered by means of an electronic device and corrected as a function of various operating parameters. In this case for each specific gear change besides the resultant translation ratio (R) as a function of the time from the initiation of the shifting process until its completion, also the first derivative (dR/dt) is formed and in the electronic device (1) values of the translation ratio (R) are assigned to the corresponding values of the first derivative (dR/dt) in the form of a characteristic line, said measured characteristic line being compared with reference characteristic lines present in the device (1) including a tolerance range and that in the case of inequality a correction factor (KF) is determined which upon the next identical gear change leads to an incremental increase or a decremental decrease in a correction value (K.sub.x) by the correction factor (KF) and thus causes a correction of the line pressure or the oil flow by means of the pressure or oil flow-impacting correcting elements (8, 9) modulated by the electronic device (1) corresponding to the correction value (K.sub.x).
