Customer replaced there own battery and now trans will not go into gear. Anything on this vehicle that needs to be done after battery replacement?
I don't believe there is... I'd be looking for a blown fuse. Maybe they touched the wrong ends...
Does it start and run fine, but the shifter doesn't move?
Do the brake lights come on? Do you hear the sound of the shift interlock releasing when you step on the brake?
Yes. Sorry I did not reply. Trans gearshift cable was off the transmission.
