Logic overdrive devices.
I have read with some amusement all the too-ings and fro-ings
on this subject with some correspondents making it all sound desperately
difficult.
What is the background? Well, when Revington TR was called TR
Spares Southwest in 1982 ish, I designed a device to allow me to change gear and
overdrive at the same time specifically with racing in mind but obviously I
found that the device was a fantastic improvement on all cars both road and
competition. I called this device a ’Logic Overdrive device’ (sound
familiar?)
Initially the device was constructed of basic electrics but
has since been redesigned and is now fully electronic.

We recommend a light on the dash to identify the overdrive
state. And it is worth noting that both negative and positive earth devices are
available.
Two types of kits are available RTR1001K which is a basic
unit suitable for both positive and negative earth and RTR1296NK, RTR1296PK
which provide a facility to dim the indicator lamp independently for both day
and night. The ‘N’ and the ‘P’ in these part numbers indicates negative and
positive earth variants.
To find out prices and more, just click on the part numbers above or type these part numbers into the
search box on our website www.revingtontr.com
That is the history and I can confirm these units have been
sold by their thousands and continue to work faultlessly in many applications
(not just TR’s) around the world, so now there is no need to go searching for
components to build a device that may or may not work, it has all be designed
for you and been field tested in thousands of cars for the last 30
years.
