GENERAL INFORMATION
The 42LE Four Speed Transaxle uses fully-adap-
tive controls. Adaptive controls are those which per-
form their functions based on real-time feedback
sensor information. The transaxle is conventional in
the use of hydraulically-applied clutches to shift a
planetary gear train. It uses electronics to control
virtually all other functions.
42LE TRANSAXLE IDENTIFICATION
The 42LE transaxle identification code is printed
on a bar code label. The label is located on the tran-
saxle case (Fig. 1).
