The car does not engage gear when sifted to reverse. High rpm will get to creep along just bearely moving. Forward gears work perfectly and car drives fine. I dont know if tranny is about to quit or something specific to reverse causing the problem. Tranny fluid clean and at rite amount
Car will not reverse unless you rev up.It doesnt engage gear in R. Forward is fine on 1992 Mercedes-Benz 500SEL
