The torque converter lock-up and disconnect clutch structure includes an independently engagable and disengagable torque converter disconnect friction clutch (24) and torque converter lock-up friction clutch (26). A first connecting member (74) is fixed for rotation with the transmission input shaft (72) and a second connecting member (79) is rotationally fixed to the torque converter turbine (60). A first friction clutch (24) selectively engages and disengages the first and second connecting members and a second friction clutch (26) selectively engages and disengages the second connecting member and the engine driven shroud (58). | |
