Ever since I had my new transaxle put in my ss/sc. My reverse light sometimes come on, however that's a rare occurrence. Did anyone ever experience this issue or know a fix... possibly where should i start to look at?

The reverse switch on the tranny(drivers side on top in front of the axel) and its wires and connector,with the install they could of pinched the wire or not put the connector on properly..
You could possibly need a new swicth ,that seems to be quite common

thank you very much
