Gearbox Sensor TR2 -TR6 for Electronic speedometer kit

Signal transmitter unit which provided the necessary electrical signal to drive our range of electronic speedometers, TR2-TR6. This unit has been specifically designed to screw into the speedometer cable output drive of the gearbox or overdrive.

The units we supply provides 4 pulses per revolution. The label on the sensor cable indicates the polarity of the sensor and the pulses. If the label does not indicate the pulses then it is a 4 pulse unit. If the polarity label has 8 pulses written on it (you're already ahead of me now) it's 8 pulses.  

 

TR's 2-3B with overdrive will find that the signal transmitter sits out slightly beyond the transmission tunnel and is slightly too large to sit within the standard Triumph speedometer cable grommet. Revington TR have manufactured a suitable 'Bulge' from fibreglass to cover the signal transmitter. Order part number RTR7277. What is entailed in fitting part RTR7277 and brief fitting instructions can be found under this part number on our website and below in 'Related Products'. TR4-6 owners may find the same problem in that part of the sensor may want to be outside the tunnel. There are many different types of tunnel for TR4-6 and many will have been changed for aftermarket ones that may or may not have an existing bulge. RTR7277 is a universal bulge and may be useful in TR4-6 applications too. If you tunnel has an obvious bulge where the sensor will want to sit, the likelihood is that an extra bulge will not be needed.

 

The sensor has a blanking cap over the unused end of the sensor body, the opposite end to that screwed into the gearbox. This end has no function and is not intended to have a speedometer drive cable attached.  

 

A bolt counting sensor RTR8558-2 is available too for those who wish to devise their own installation.

 
The speedometer comes with manufacturers fitting instructions however additions helpful notes specific to a TR installation are to be found in Information sheet IS0061, downloadable by pressing the 'Further Reading' tab above.
