Where is the Gear Position Sensor?

[Ray_B]

I received my TT back from a long shop visit for cosmetic damage, 20k service and a service bulletin head replacement. Now when I downshift from 3rd to 2nd or 2nd to Neutral, the gear display stays at the higher gear for a few seconds before displaying the correct gear. Up-shifting does not have this issue. Im a bit leery of going back to the dealer after the long stint last time so does anyone know where the sensor is and if it's something that can be adjusted without opening case?

Hi Ray_B,

The Gear Position Sensor (1 ) is just in front of the upper Gear Pedal Linkage.

The Service manual says to remove the left side Fairings, then
remove the cover that houses the Electrical Socket -
just one bolt then it pulls off from two rubber grommet type mountings.

You will then see the Gear Position Sensor bolted onto the side
of the gearbox and secured by two standard hexaganol bolts ( 2 ).

Cheers

Coconut, as usual, you are the go-to guy when it comes to TT knowledge! Thank you!

You should be aware that some Triumphs (not just the Trophy) suffered from failed shifting sensors.  Mine did.  Find a good dealer and tell them to check your bike pursuant to Triumph Technical News 143, issued April 2013.  Note this is a Technical News, not a TSB and not a recall.

I have the Trophy SE Service Manual and can't find any mention or pic of this sensor. Did you find it in the Manual or somewhere else?

Hi Ray,

The information is in the Service Manual,
but not where you would expect to find it !

It's NOT in the Gearbox / Transmission Section !

I'm not at home right now so can't check,
but IIRC it was further back -
I "think" in the Body & Frame Section ! 

I will confirm later when I get back from the Pub !

If you get your dealer to provide you a copy of the technical news I referenced Triumph Technical News 143, issued April 2013 it has all manner of diagrams

Thanks guys! I'll dig deeper & also ask the dealer for the TN.
