4MATIC Transfer Case, Function - GF28.10-S-1000TRA
Model 447 With Transmission 722.965
Automatic transmission with transfer case
4MATIC transfer case, general
The transfer case (3) is integrated into the rear section of the automatic transmission (5). What makes it so special is its single-stage output with integrated constant velocity joint. The single-stage version, in contrast to the dual-stage output of previous transfer cases, no longer requires a spur gear set including the bearing. This has a positive effect on efficiency, weight and the noise characteristics of the drive train.
In case of repair, certain components of the transfer case (3) can be replaced separately. It is not essential to replace the complete transfer case (3) along with the automatic transmission (5).
