Replacing Downshift Prevention Control Unit

Replacing Downshift Prevention Control Unit




The downshift prevention control unit prevents racing the engine when operating kickdown with the selector lever in D and at top speed. Downshifting from 4th to 3rd gear is prevented by a solenoid valve in the transmission depending on the speedometer signal. Downshifting is only possible after reducing the speed.
