Selector Detent Spring is part of the gearbox gear-selection detent for the forward-gear selector shafts (1st/2nd and 3rd/4th).

It loads the detent ball against the selector rail so each rail is held positively in its selected gear or in neutral, preventing the gear from creeping out of engagement. Worn or missing detent springs are a common cause of gears jumping out. Used on the 4- and 6-cylinder gearboxes; the reverse selector uses a separate spring (56102).

Frequently asked questions

What does the selector detent spring do?

The selector detent spring loads the detent ball against the gearbox selector rail, so each forward-gear rail is held positively in gear or in neutral. It covers the 1st/2nd and 3rd/4th selector shafts, stopping the gear creeping out of engagement.

What are the signs the detent spring needs replacing?

Worn or weak selector detent springs are a common cause of gears jumping out of engagement on the move. If a forward gear won't stay selected, a tired detent spring is a likely cause. Replacing it restores the positive detent that holds the rail in gear.

Does this spring fit the reverse selector too?

No, this is the forward-gear detent spring for the 1st/2nd and 3rd/4th selector shafts. The reverse selector uses a separate detent spring, part 56102. Order that one if you're working on the reverse rail rather than the forward gears.

Which gearboxes use this selector detent spring?

This detent spring fits the Series 1, 2, 2A and 3 forward-gear selector shafts on both the 4-cylinder and 6-cylinder gearboxes, covering 1948 to 1984. Confirm your gearbox is the Series main gearbox before ordering.
