I have a Volvo 440i Automatic and love it. Problem is that I lost all transmission without warning except reverse and am puzzled. I got the car home and checked the fluid level which is fine and no leaks. When I tried the car the following day, Drive was back and I took it for a spin and lost the drive again as soon as it warmed up. I only went about half a mile round the block. No warning lights, no funny noises except that when I lose forward momentum it sound like the car is stuck in neutral, just revs and nothing else.
Is my poor baby terminal or am I just being a bad father?

A new gearbox is going to cost me around £950.00 fitted so please help if you can guys and gals.

Have you checked into getting it rebuilt?
Sounds like you need a trans or a good rebuild.

if you've got the time and patience etc to do it yourself, then its probably worth buying a donor car and moving the box over. Its a pain of a job because you have to lift the engine completely out of the car, but if you like the car then it might be worth doing - look on ebay - 440's go for peanuts on there - certainly less than £950 for a new one fitting!!
