ok i noticed my back-up light were not working, i found the switch bad got a new one today and tested it before screwing it in but it is not working when installed? what could be the problem? Inside the manual trans?
thanks for the help.

is there power at the switch?

 

with the switch out i can push the metal ball in and the lights come on.

 

sound like something inside the transmission might have broke.

 

the problem was that the replacement from the store was too short manufacter defect. got one from a different store and it works.
