B1, B2, K1, K2, K3 Accumulator Piston Kit
Wear at the accumulator bores in Aisin Seiki AS66RC and AS69RC units is very common. The B1, B2, K1, K2, and K3 accumulator pistons are all the same size and are used during apply of the clutches to ease the engagement of the apply component. Wear at the valve body bore allows apply oil to exhaust, resulting in harsh or delayed apply, burned clutches, or slipping and flares in the associated gears.
