Technical issues and repair guidelines
The Lepelletier toothed gearing solves the problem of matching gearboxes’ gear sets and clutches. So this gearbox employs just 5-clutch sets to get 6 forward gears. 6R140 is reinforced by the usage of a metallic powder carrier within the compounded gear set. The carrier consists of four compressed elements, which are forced together to form a hard composition. 6R140 has a new torque converter which contributes to longer operability and a high-powered turbine damping mechanism introduced to smooth the force from the engine.
