Abstract
A torque converter assembly configured to be connected between an engine and a transmission in a vehicle. The torque converter assembly comprises a cover plate having a cover plate pilot portion, a pump, a turbine, a stator, and a clutch assembly operably connected between the cover plate and the turbine. The clutch assembly comprises a piston plate having a single clutch face and a piston pilot portion. The cover plate pilot portion and the piston pilot portion are both configured to be piloted by the engine. A pilot plate located between the cover plate and clutch assembly can help control the amount and/or velocity of fluid that hydrodynamically connects various portions of the torque converter assembly.
