Has anyone ever made a claim on the powerflex lifetime warranty? It's hard to explain but sometimes when changing gear I think the car is in third, when it's actually in neutral. Not the best description but this issue was fixed when I had the gearbox and lower engine mounts fitted. Since the problem has come up again I can only presume the mounts have worn excessively. The claims process looks easy enough, but I was wondering if anyone had any experience making a claim.
