I've just had a 5 speed dccd gearbox fitted into my 1999 uk turbo and it doesn't want to go into reverse with the engine running.if I try I just get the noise of grinding cogs.if I put it in reverse before I start the engine then it works fine.all other gears select fine.anybody have any ideas on a solution or do I have a duff box? Thanks in advance
