ABSTRACT:
A kit and a method are provided for modifying an automatic transmission such as a turbo-400 hydromatic transmission. Before modification the automatic transmission couples an engine crankshaft 4 to a forward clutch drum assembly 3 through a fluid coupling such as a torque converter. This kit provides a lockup shaft 10 selectively coupleable between the engine crankshaft 4 and the forward clutch drum assembly 3. As modified, the forward clutch drum assembly 3 can be selectively driven either off of the torque converter turbine 32 or off of the lockup shaft 10 coupled mechanically to the engine crankshaft 4. The lockup shaft 10 extends through intervening structures from the crankshaft 4 out to the modified forward clutch drum assembly 3 where it connects to a lockup hub 20. A drive tube 30 of hollow cylindrical construction surrounds the lockup shaft 10 and is secured to the torque converter turbine 32 within the torque converter housing 8 which is driven by the torque converter pump 9. The drive tube 30 is also coupled to a lock-up drum 40 and forward drum 50, along with a direct hub 60. A forward piston 80 and lockup piston 90 along with forward clutch plates 88 and lockup clutch plates 98 cause the modified forward clutch drum assembly 3 to selectively lock to a forward clutch hub 70 in a manner either providing rotation to the forward clutch hub 70 at the rate of the drive tube 30 through the torque converter turbine 32 or to the lockup shaft 10 at a rate matching that of the engine crankshaft 4. A lockup mode for the automatic transmission is thus provided when desired which provides direct coupling of the engine crank shaft 4 to the forward clutch drum assembly 3, effectively bypassing the torque converter.
