My 76 step side originally had a 3 speed manual transmission according to the previous owner. It failed while he was towing something on the highway so he wound up putting in an automatic transmission....a TH700R4 a.k.a. 4L60 and not the "E" version. My question is how does the reverse light activation take place? I hate to bring up my Dodge truck on this forum but it has a 3 speed manual transmission and there is a reverse light switch mounted on the left rear of it. Was the chevy set up the same way? and now since it is an automatic how would i get the reverse lights to actuate now? Any help would be greatly appreciated.
