petegardner_901 Posted November 8, 2021 Report Share Posted November 8, 2021 Sorry if this is a dimwit query but how do I tell which gearbox I have? Single or 3 rail? 1979 late Spitfire 1500 p Link to comment Share on other sites More sharing options...
johny Posted November 8, 2021 Report Share Posted November 8, 2021 Hi, your box should be a single rail and look like this unless it has overdrive in which case it'll have the the same gear lever system but mounted on top of the much bulkier overdrive unit...

Pete Lewis Posted November 8, 2021 Report Share Posted November 8, 2021 where as a 3 rail with the OD missing looks like this if you look at the top cover you can see the ends of the plug/caps that seal the 3 rails of selector shafts Link to comment Share on other sites More sharing options...

NonMember Posted November 9, 2021 Report Share Posted November 9, 2021 Also, reverse is left of first on a 3-rail, right of 3rd on a single rail. (It's right of 4th on a "big saloon" box) 1 Link to comment Share on other sites More sharing options...
DVD3500 Posted November 9, 2021 Report Share Posted November 9, 2021 I think 3-rail is also push-in and single rail is lift-up.... right? Link to comment Share on other sites More sharing options...
Pete Lewis Posted November 9, 2021 Report Share Posted November 9, 2021 always fit a plain gear knob the mis match of ideas here helps foil the stealer from backing it off the drive Ha ! and as we get older gives us something to have to concentrate on its over there no its over here ....Grr Pete Link to comment Share on other sites More sharing options...
DVD3500 Posted November 9, 2021 Report Share Posted November 9, 2021 In the US just having a manual shift car was enough to stop most thieves! 2 Link to comment Share on other sites More sharing options...

My Grandson, was the only one in his year in high school, to use a manual!. He practiced on my old car over here, on farm roads, during summer break.

petegardner_901 Posted November 9, 2021 Author Report Share Posted November 9, 2021 Excellent! Make sure the solenoid is perfect before you bung the whole unit in the car as the lower attachment screw for the solenoid is almost impossible to get at afterwards…😩 1 Link to comment Share on other sites More sharing options...
Colin Lindsay Posted November 9, 2021 Report Share Posted November 9, 2021 IIRC the solenoid for the D-type is also much cheaper than for the J-type, by a massive factor. Link to comment Share on other sites More sharing options...

Might be a tad long and will adjust length when fitting . This will ensure the solenoid will never fail 🤔 Paul 2 Link to comment Share on other sites More sharing options...
