Hi I have a 2005 ford focus 2.0 automatic. I was reversing out of my drive no problems put the car into auto and the car jerked forward then made a loud clunking sound and wouldnt go. I can drive the car in reverse but it jerks badly into gear. If I put the car into neutral I get a very loud rattling noise from under the car along with loud grinding. Whats wrong?

Does this mean I need a new gearbox and is this problem expensive to fix?

no you do not need a new gearbox just the metal drive plate --if this is the problem that is but without a look myself i honestly couldnt say and no one can answer this no matter how tgood they are without a physical inspection ,but if it is this drive plate thats broke that part on its own is not expensive as such but its the labour involved in removing the gearbox to change it no you do not need a new gearbox just the metal drive plate --if this is the problem that is but without a look myself i honestly couldnt say and no one can answer this no matter how tgood they are without a physical inspection ,but if it is this drive plate thats broke that part on its own is not expensive as such but its the labour involved in removing the gearbox to change it
