PERFORMANCE Transmission Garage Therapy Overdrive Unit DA3338 As with all gearboxes, lubrication failure due to Garage Therapy Overdrive Kit - 4-Speed (LT95) excessive heat, lack of supply, or both, is to be Range Rover Classic - 1970-1983 avoided at all costs. To handle the extra heat generated by the overdrive gearbox, a finned The kit includes: transfer case cover is included which doubles the > GT-LT95 overdrive heat rejection compared to the standard cover. > 2 piece LT95 coupling If even more cooling is required for high speed, > Coupling spacer high load in hot climates, the cover has ports for an > Finned transfer case cover and gasket optional oil cooler and manual temperature sensor. > Digital temperature gauge kit including 2 sensors > Overdrive selector kit To assist this, an accurate digital temperature gauge > Installation manual is supplied. This very clever gauge uses simple lug style sensors that can monitor both engine and It has been specifically designed to fit the restricted space of gearbox temperature. Unlike traditional sensors, the 1970 - 1983 Range Rover Classic that use the Rover LT95 they operate independent of oil level. It even has gearbox. Comes with everything required to complete the an optional exhaust gas temperature thermocouple installation. Because the overdrive has been designed to fit available; perfect for turbocharged applications. Not onto the PTO flange area of the Land Rover LT95 gearbox, only does the gauge have simple to understand you can enjoy the 28% overdrive in any gear, including icons that change colour if safe limits are reverse, and in high or low range. exceeded, it also has a series of audible alarms so you never miss that vital warning. Garage Therapy have worked closely with Global Roamer Corporation of Canada to develop a robust overdrive that will allow you to enjoy quieter, more fuel-efficient cruising on motorways and the ability to split every gear while towing heavy loads. It also allows you to overdrive all gears in low range, reducing engine noise and wear on those long sandy tracks and beaches. The GT-LT95 overdrive takes advantage of Global Roamer’s legendary epicyclic gear train technology as used in their Roamerdrive overdrives. Also known as planetary gear sets, they are well known for their strength and silent operation. Global Roamer Corporation has a worldwide population of You many thousands of overdrives using this very same bullet- proof technology. can Many of the older style ‘layshaft’ overdrive units suffered enjoy badly from a lack of lubrication. The GT-LT95 is designed the 28% to be open to the transfer case and utilises an innovative lubrication system which directs transfer case oil through the overdrive in overdrive gearbox and back to the transfer case via a large deep groove ball bearing. any gear Photo by Jonathan Anderson 163
