Transmission shift valves with latching control |
摘要 |
A power transmission has a plurality of shift valves each of which has an engaged position and a disengaged position. Each shift valve has a pair of chambers which is selectively pressurized by a latching valve to maintain the shift valves in their respective selected positions. During a ratio change, the latching valve discontinues pressure at the respective shift valve chambers to permit the appropriate shift valve movement.
