A Type Overdrive Technology

TR6 A Type overdrives represent the later Laycock design, offering improved reliability over earlier J Type units through refined internal components. The hydraulically-operated system engages smoothly when the Triumph TR6 overdrive electrical components function correctly. A Type units mount behind the gearbox, requiring specific Triumph TR6 propshaft configurations for proper drivetrain alignment.

Service and Rebuilding

A Type overdrives benefit from regular fluid changes using the correct ATF specification. Worn components cause slipping or delayed engagement, requiring professional attention.

Smooth overdrive operation transforms motorway driving. Browse our A Type components for reliable long-distance motoring in your TR6.
