A quick increase in engine speed along with a momentary loss of torque during a shift transition - also defined as Slipping

More noticeable clutch apply than Firm - considered unacceptable at any throttle position

A repeating quick series of upshifts and downshifts that cause a noticeable change in engine speed, such as 4-3-4, etc. - sometimes defined as Cycling

A distinctly firmer feel at the start of a shift than at the finish of a shift

A shift that occurs at a higher speed than normal for a given throttle position

Multiple, rapid jerks usually associated with an oncoming clutch

A noticeable increase in engine speed without an increase in vehicle speed - usually occurring just after the initial application of a clutch

A slow, almost unnoticeable, clutch apply

A repeating engine-related condition of acceleration and deceleration that is less intense than Shudder

A condition where 2 opposing clutches, usually 1 oncoming and 1 offgoing, are applied at the same time - giving a braking sensation and/or loss of engine speed
