Auto Transmission General Info Automatic Transmission General Information Interpretation of adaptation data What is pressure adaptation? Pressure adaptation is responsible for the quality of the gear shift The pressure adaptation figure affects the time difference between receipt of the shift signal and reduction of the turbine speed Example:Adaptation data for a gear shift The tester printout produced the following figures

Automatic Transmission General Information Interpretation of adaptation data Note: The tester printouts shown are examples used in order to illustrate the information contained. Under no circumstances should they be used as the basis for generalisations A definitive interpretation can only be made by specialists
Automatic Transmission General Information Interpretation of adaptation data Software updates can change the adaptation data The aim of an update is to improve the gear shift quality Consequently, it is of the greatest importance in the case of complaints relating to automatic transmissions to obtain a read-out of all information from the transmission control system A road test should also be carried out to obtain a precise description of the fault and this included in the enquiry
