No reverse 2011 Zetec diesel mondeo

[Paulvitti]

Hi All,

I am big Mondeo fan and have been in the game from since 2013 when I brought my first Mondeo from Surry Hills Sydney. It had about 60k high way kilometers on it.
I loved driving my mondeo every where and on long drives mainly. It has 288k at present. When I was in Adelaide I did a transmission services for the first time which I guess was a big mistake as they were not transmission specialists.

In mid last year I heard some kind of sound coming from the bottom of the car. I also felt jerking or stuttering on the signals. Sure thing after few days car would not engage in reverse. I did not receive any messages on the dashboard re transmission or anything.
I have read some online forums and figured out that transmission is gone possibly.. and I end up buying patrol Mondeo but believe me its not fun to drive and thirsty on fuel.

I have changed the dpf couple of years ago and got an aftermarket one. I probably have an old battery. would could have gone wrong here? is the transmission gone or something else?

If its going to cost me a lot to fix transmission then not worth it but everything in the car is tip top and car was well look after.
