In this transmission angular cone bearings are used for all shafts. These bearings require a certain amount of play and pretension. The required amount of bearing play and pretension is achieved at the production stage by using shims under the angular cone bearing in the transmission housing.
Location of Gearwheels
This diagram shows the location of the gearwheels on the respective shaft.

Transmission adaptive values learn
Transmission Adaptive Values Learn is a procedure for 6 speed automatic
transmissions in which a series of
tests are run to allow the transmission control module (TCM) to learn individual
clutch characteristics. Once the
clutch data is learned, Transmission Adaptive Values Learn translates it into
Lifting and jacking the vehicle
NOTE: The use of a LOW PROFILE LIFT ARMS SYSTEM may be required to
avoid
unwanted contact with the vehicle's body and structure depending on lifting
equipment used. Refer to the manufacture's recommendation for their
applications of low profile lift arms system for their lifting equipment.
