Gearbox malfunction

[Focus on 56plate]

I'm looking for advice.

My car is a Ford Focus Zetec 1.6 diesel automatic with the option of manual override on a 56 plate, just over 90K mileage.

I recently broke down driving home from a holiday in Somerset.

The issue is transmission related, I have little or know drive forward or backwards, if feels and sounds like a slipping clutch.

so far I have been unable to get anyone to look at it, cannot drive to the garage, everyone including a Ford local dealership suggests due to age and mileage, scrap the car.

I do not believe the car has a transmission dip stick, so no way of checking the transmission fluid.

Has anyone else experienced an issue like this and got any advice, the car has been serviced every year since new and up to this point has been an excellent runner.

if it has to be sold for scrap or breaking, so be it, but I would hate to discard what I still see as a good car, just!

Thank you in advance
