  1. 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

  2. Automatic Transmission General Information Adaptation data for a gear shift 32 Address of control unit 08 Message length a0 Test bit/confirmation Adaptation figure for change to D 00 0a Adaptation figure for change to R ff fe 91 Checksum

  3. Automatic Transmission General Information Adaptation data relating to pressure 32: Address of control unit 3b:Message length a0: Confirmation 32 3b a0 fe fe 00 fc fe Information relating to gear change from 1-->2 and speed data 06 04 08 02 02 Information relating to gear change from 2-->3

  4. 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

  5. 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
