Does anyone know where in the UK to get a c6 2005 4 speed auto box fixed. It’s my friends who lives in Plymouth. We would have a new member then, it’s an awesome car

A lot of auto box problems are just oil and filter needing changing.
I am assuming these have been done first, just to make sure of the obvious.
