145 Data Parameters Transmission Parameters For 01M, 01N, and 01P transmissions, the solenoid valves #1, #2, and #3 govern the selection of various gears inline with actuation by the TCM. Solenoid valves #5 and #7 create the necessary prerequisites (pressure) for proper clutch apply and release. NOTE: i Solenoid #4 is a modulation type for torque converter lockup that does not read amps. This solenoid shows ACT or N.ACT. To look at how much modulation is taken place, see LOCKUP SLIP on page 142. Solenoid #6 is timing valve and is responsible for pressure regulation. See ACTUAL SOLENOID(A)” on page 140.
