摘要：A power transmission control selectively establishes five forward speeds and one reverse speed by the controlling of three relay valves and two variable pressure TRIM valves. The TRIM valves normally control the pressure in the on-coming and off-going friction devices, respectively. The TRIM valves switch functions between ranges. In the fifth speed, the relay valves provide a pathway or passage for directing the fluid output of one of the TRIM valves to a control area on a system regulator valve to effect a variable main pressure.
