The transmission uses two accumulators:
1-2 Accumulator — The 1-2 accumulator is used to soften the 1-2 shift by absorbing some of
the pressure directed to the intermediate clutch. Constant line pressure is applied to the middle
section of the 1-2 accumulator piston, opposing the intermediate clutch pressure, until the
pressure is high enough to overcome line pressure. The top of the piston is exhausted to the
sump.
2-3 Accumulator — The 2-3 accumulator is used to soften the 2-3 shift by absorbing some of
the direct clutch pressure. Forward clutch pressure is applied to the top side of the 2-3
accumulator piston, holding the piston down until clutch pressure is high enough to overcome it.
The middle section of the piston is exhausted to the sump.
