Have a GTM with a Mendeola SDR5 transmission and there seems to not be any kind of reverse lockout. It is pretty easy to be going down the highway and instead of going from 4th to 5th you end up trying to go into reverse. Maybe this is a shifter setup issue, or maybe a cable adjustment issue, maybe there should be some type of reverse lockout. Car has shifter cables. I have looked everywhere and can not find any information on a reverse lockout for the Mendeola. Any information would be great as I have no idea on this.
