Accumulator piston noise
Pressurized fluid headed to the clutch pack apply piston or servo pushes on the accumulator piston. At the same time, the fluid also moves the apply piston to compress the clutch pack or the servo to apply the band. Because the fluid must also compress the spring under the accumulator, it delays or lengthens the shift timing slightly.
