FYI: interesting article on CVTs reveals the following:
CVTs without a torque converter are typically driven through a dual mass flywheel or a torsional damper plate that connects the crankshaft to the input shaft. The BMW Mini Cooper VT1F, the Audi A6/8 01J and
Honda Civic (photo 3) CVTs are examples of this design. To prevent a stalling condition when the transmission is placed in gear or when it comes to a stop in gear, a clutch inside the transmission must release. The VT1F and 01J CVTs release the forward or reverse clutch, while the Honda Civic CVT releases a start clutch in both Drive and Reverse. These clutches are pulsed on and off very frequently and are susceptible to failure. This can cause a variety of complaints, such as chatter on takeoff, sudden slipping or neutralizing conditions, unusual idle fluctuations or a loss of hill-hold function.
