W124 220e Reverse issue

[sharmas71]

I have just aquired a 1994 220te Auto
Lovely car 167k miles with an auto transmission.
Put the car in drive , engages superb and pulls like a train.
However put the cat in reverse, it goes in but without a positive thunk as you normally get.
When you apply the throttle,its behaves like a slipping clutch!
Any ideas or will i have to replace the gearbox....

It's a typical W124 gearbox fault. There's a reverse clutch that tends to fail
