Car will not reverse unless you rev up.It doesnt engage gear in R. Forward is fine on 1992 Mercedes-Benz 500SEL

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
