Dear DR ///AMG:
Do NOT use any Lucas products in your car. I've seen demonstrations of Lucas engine, power steering and differential additives in action, and they all cause terrible foaming by sucking and trapping air in the oils. The foaming very much destroys all lubrication properties of the base oils.
Stay away from them! Useless and dangerous.
When reverse gear doesn't work properly or slip, it is the reverse clutch pack causing the problem. M.B. Doc once told me that parts for that kind of repair don't cost much, but there is a lot of labor involved (which translates to big chunk of dough).
Changing new ATF fluid does not help. You have to live with the slipping reverse problem until it's completely non-working, or have your transmission R&R. Nothing else can help.
Been there, done that.
