LOGIC OVERDRIVE DEVICES

This clever device allows for fast and sequential overdrive operation. The overdrive cannot be left engaged inadvertently, reducing strain on the overdrive and when changing gear with the overdrive engaged the overdrive drops out automatically.

This makes for swifter and more precise driving and reduces strain on the overdrive. Two systems are available, a basic unit and a more complex version which dims a dash mounted indicator lamp when the sidelights are switched on. The lamp is not included in the kits but is recommended due to the operating switch being a momentary make type giving no clear indication of overdrive state.

These units make the driving experience of any car fitted with electrically operated overdrive a real pleasure, turning your 4 speed gearbox with 3 overdrive gears into a virtual 7 speed gearbox.

Eminent race and Rally driver, Jean Jacques Thuner was suitably impressed when he drove the works TR4 registered  6VC back in 1999. with our logic device fitted. You can read that story HERE.

Neil Revington reports that at his first outing to the Mdina GP in Malta, a fellow competitor questioned after practice if I had a sequential gearbox in my TR5! Our logic device can even impress onlookers. You can watch the You Tube video  via the icon below. Watch out for the light on the dash inside the rim of the steering wheel coinciding with overdrive engagement.
