Customer Question

Hi Mark. My hummer H3 2009 is stuck in reverse.
I have disconnected the battery and reconnected hoping it would reset the computer.
Any thing I can do to get it moving again?

Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.

Usually what can fail and cause this issue here is a fault with the shifter cable that runs from the shifter to the transmission.It seizes up and causes it to become stuck like this here.The way to find out for sure if this is the cause here is to disconnect it from the transmission and the shifter and see if with the wheels blocked with the vehicle on the ground if the transmission can manually be shifted at the shift lever on the side of the transmission and the shifter shifts then.If they both do then the cable itself needs replaced.

If the transmission shifts manually but the shifter does not with the cable disconnected then the mechanical shifter itself is at fault needing replaced.If the shifter shifts and the transmission does not with the cable disconnected then the transmission has an internal mechanical fault and needs inspected internally to locate and repair the fault.
