I can't see what difference being automatic would make. If a welded diff could blow an auto, it could blow a manual.

I can understand your reluctance. Do you have any history of the repair? If its just been done and you don't know why/trust it then I would get a replacement. If it was done 10's of 000's of miles ago then its likely to be fine.

No doubt Benfur (a fellow LOC member) would have a replacement and Simon Taylor has a breaker at present. PM them.

Fair enough. In that case I would check the oil level and then try the car, stereo off, all windows down and listen and feel. Any noises from the transmission or jerks in the drive and I WOULD lay it up until another diff can be fitted. If all seems good, treat it gently.

and avoid sharp corners or your tyres will be history pretty quickly.

I get 25000 from my tyres.

On a good run, driving at speed limits and without racing starts/stops I get 32. In town this drops to 20. If you drive like a boy racer you can half these.
