Description

Sleeve coupling for either the SPL311 4 speed or the SRL311 5 speed “Servo” type transmission 1st/2nd or 3rd/4th gear; two (2) total may be needed when rebuilding your transmission. This part is under a part number from the Nissan / NISMO “secret” catalog and different than the roadster part number (although they are interchangeable) and was probably produced and used in the BS110/240RS transmission according the the long term parts manager I acquired them from.

The sleeve coupling for the 5th / rev. position is different than this coupling and can’t be interchanged with this one, however it is fairly rare that the 5th / rev. coupling needs to be changed when rebuilding a U20 5 speed transmission.
