I'm wondering if there is any way to positively confirm whether the CVT's torque converter is locked-up or not on my 2016 Forester 2.5i. This is the one time I wish it were capable of a fixed ratio as is available with the paddle shifters. Any throttle input significant enough to increase speed results in an RPM increase before the speed starts to increase. I am uncertain if this is the result of a ratio change of the CVT, or slippage due to an unlocked torque converter. Is there anyway to positively tell the difference?
