Customer Question

My CAT 420e will not reverse in any gear. This is a shuttle shift transmission not a power shift. The dash light indicates malfunction in machine system.

The E model lacks any diagnostic help on the electronic controls. Unfortunately, that means the dealer is needed to find the actual fault code and trace out the issue.

About all we can do is test a harness for a fault and maybe a solenoid.

If you would like to try this, please post the full machine serial number so I can research the correct information for you machine.
