Gearbox help

[S4andy]

Good evening

 

I am after some advice please.

I currently have an s4 b8 2013 advant and its my pride and joy. However I have started to hear a noise from the gearbox when changing into 4th gear. It sounds like something is stuck under the car and is catching something. Again like a metal noise. Its an automatic gear box.

 

I think its the dreaded gear box on the way out.... I'd like to hear if anyone has experience of this and what is the possible solutions?

 

Many thanks in advance

 

Andy
