LOCK-UP SLIP ________________________________________________ (range 0 to stall) Indicates torque converter lockup slip on a P transmission. When in the hydraulic gears, the torque converter lockup must be open with 0 to stall RPM slip. With engine speed 2000–3000
143 Data Parameters Transmission Parameters RPM in the mechanical gears, gear completed, the torque converter lockup clutch must be closed and the accelerator pedal value held constant with 0 to 130 RPM slip. PRESSURE CTRL(A) ____________________________________________ (range variable) Indicates the pressure control amperage of the #4 solenoid. It controls the pressure for actuation of shift elements (modulation pressure) as a function of engine speed, engine torque, and transmission oil temperature. REQUIRED SOLENOID(A)______________________________________ (range 0.0 to 1.0A) Indicates the specified current the TCM would like to see through solenoid A, which is the electronic pressure control (EPC) solenoid, on 095, 096, 097, 098, MN, and P transmissions. It should read 0.0 at WOT and 1.0 at closed throttle. This value should closely match Actual solenoid (A. Code set if actual and required vary by 0.050 A or more.
