Manual Transmission Components
TR6 gearboxes use traditional British engineering with brass synchromesh rings that wear through enthusiastic use. The transmission bolts to the engine via Triumph TR6 clutch assemblies and mounts on the Triumph TR6 engine mountings for proper alignment. Overdrive-equipped boxes feature either J Type or A Type units bolted to the tailshaft, requiring specific Triumph TR6 propshaft lengths.
Gearbox Rebuilding Requirements
Synchromesh wear causes difficult gear engagement. Professional rebuilding restores crisp shifting through correct clearance specifications.
