freelander 2.5 v6 auto wont reverse

hi my mums freelander 2.5 auto wont reverse properly just judders it will creep back on its own but will just judder if you accelerate any ideas?????????

when did this start?
did yu have anything done just before it started?
have yu changed the oil in the gearbox?

well my mum said it started about 4months ago and the only thing that has been changed was the rear prop shaft and i changed the oil in the box to see if that would solve it but it didnt just puzzled with it

There’s a bolt at the rear of the auto, which holds part of the reverse mechanism in place. Some mistakenly undo this as it looks like an oil level plug. It’s not. The mechanism falls off inside, and the auto has to be opened up to put it back. This is a known cause of loosing reverse gear. Often garages do it by mistake when they don’t know what they’re doing. Is it possible someone worked on the car 4 months ago and undone this bolt? Perhaps a little before this?

it could of been touched before my mum got the car but when i did the oil i looked it up on what to undo so it wasnt me but the oil i took out the box didnt look that old so is very possible will have to investigate this cheers for that
