Hi all I've got a 2014 fiat Punto 1.2 it had a new rear crank seal and clutch fitted today and now every time I attempt to engage reverse it grinds worse than when I took it to the garage it's the second clutch and rear seal in 2 years it's had a refurb box 3:years ago and new linkages a couple of months back has anybody have any idea what the issue could be when the car is off it goes straight into reverse with no issues thanks in advance for any advice
