Hi everyone just found this great forum and learnt alot already but i have a question regarding my gearbox
First off car details
MK3 2.0 (Agg) GTi 8v Anniversary
Problem is since i have had the car about a year it goes into all gears fine without a hitch drives good
but it jumps out of reverse is this a common fault or does anyone know what could be wrong

I am a mechanic but work for fords if these boxes are easy to fix i may have a go but would prefere to get it done by someone who knows the boxes
Thanks
I am in the chester area if anyone knows anywhere to go
