What is a bad 4L60E 1-2 accumulator?
If you’re accelerating and suddenly experience a pronounced delay, shudder, or “bang” during the 1-2 shift, then you probably have a bad 4L60E 1-2 accumulator. These little parts act as a sort of cushion to absorb the excess fluid pressure that forms inside the valve body during a shift. GM used plastic pistons on the inside of the accumulators, and they can break off over time. To keep the remanufactured 4L60E transmission in your Yukon on the road and out of the shop, Street Smart Transmission installs sturdier aluminum 1-2 accumulator pistons, and the valve body is recalibrated to improve the fluid pressure control.
