Hello! Let's see if we can can work together to get to the root of your question!

Expert:  Curtis B. replied 7 months ago.

What is this? Genie boom? Older 42-4X4 , or a newer 42C? High speed is only available when in two wheel , high drive. Reverse works same as forward, so I would suspect the reverse section of the control valve solenoid is not getting voltage.

Expert:  Curtis B. replied 7 months ago.

I could not locate your model. I will opt out, maybe someone else can help. Sorry.

Expert:  Curtis B. replied 7 months ago.

I found what I think is the model. TB42A. Here is operators manual. High speed is only available with the boom in the stowed position, which there is a switch that has to be closed. Check the switch , t see if it is making contact. Then for the no reverse, locate the forward valve on the drive valve body, and next to it will be the reverse valve. Check the voltage for forward , then reverse, if no voltage for the reverse valve try putting voltage to the reverse valve to see if reverse works. If there is voltage to the reverse valve from the controller, then swap the valves.
