Hummers: Drivetrain, drive shaft, valve body


Question
Where does the H1 Hummer achieve drivetrain reversal?


Answer
Aldo,

Please rephrase your question.

I am not sure what you  are trying to find out. For example do you want to know which way the drive shaft is spinning on the transmission output or which way it is spinning when entering the geared hub?


The H1 when put in reverse is like any other vehicle. Reverse is selected at the gear shift and the transmission is then by the valve body placed in reverse and the vehicle moves backwards.
