Service Information: Heating up automatic transmission fluid for testing and repair work

 In this Service Information bulletin, we would like to point out that simultaneous operation of the throttle and brake in order to heat up the automatic transmission fluid faster for testing and repair work on the transmission is forbidden in all cases.

The latest damage analyses of transmission and converter have shown that thermal overloads at the transmission and torque converter occur as a result of this procedure. This causes pre-damage to these components.
