The Big Red Merc lunched its gearbox after 264,000 miles.
I've sent out a PartsGateway request and a couple of requests on Merc breakers I found on the net. There are a couple on eBay but can't access that from work as it's blocked :(
I only changed the gearbox oil on Monday as I thought it was a bit noisy!!
That is the third car I've owned that had a gearbox fail. My first car, a Fiesta (lost access to third gear). The Rover 620TI (which was always going to happen) and now Big Red (don't know what happened - SWMBO was driving it at the time, ironically because her car's in the garage having a wheel bearing done today).
Luckily it happened in a relatively convenient location. It could've been on the way to taking friends to the airport or miles from home. SWMBO said people driving past were looking at her with "what do you expect with such an old car" eyes.
