Recomendations for a good automatic rebuild

[Auto]

Hi can an any of the automatic experts on here please point me in the direction of a good automatic mechanic
to rebuild my late VW t25 automatic gearbox ? I'm in south Yorkshire but willing to travel if necessary it's working
ok at the moment but has started to make a whining noise so needs doing sooner rather than later before it wrecks its self
and requires more serious work
Either that or point me in the direction of a good used one
Any help would be much appreciated
Cheers phil
