The following diagram shows the location of the detent pin (item 24). Unfortunately I cannot remember if its access was possible without removing the gearbox, I imagine it is tight though. My problem was the pin rocking, making it very difficult to come out of gear, maybe it would also be worth checking that the spherical bearing on the gear stick has free movement.

Thank you all for the advice. After chatting to Phil at Road and Race Transmissions it is almost certain that the problem is the operation of the detent location pin. Instead of simply moving in and out, it is also rocking side to side which makes it more difficult to disengage from the selector rail. I understand this was an issue early gearboxes but as mine is circa 2013 I am surprised it has the problem. Does anyone know how to determine the year of manufacture from the serial number? Mine is - 70000CSR AAT0EK12 Thanks Dave

Hi All, Does anybody know if these gearboxes can develop a fault that makes it very difficult to de-select 5th or 6th gear? This problem has been progressively getting worse on my gearbox (only 6000 miles from new) to the point at which it is almost unusable. I have removed the gearbox and tried to identify the problem which I think is related to the selector rail and detent pin. If I remove the detent pin all gear selections/de-selections are perfect, but when I replace it with a low spring tension it still sticks in 5th/6th. I have included a few images that hopefully explain things better and also show extra wear on the 5th/6th locations on the selector rail. Thanks Dave.

Hi Tom, Not sure if this picture helps, but the wire broken from the sensor terminal caused the gauge to indicate Full regardless of fuel level in tank. Dave. /sites/default/files/images/users/3731/FuelGauge.JPG
