NVL
As a diagnostic response:
If Turbine Speed is below 150 rpm when Output Speed is below 100 rpm and Engine Speed is
above 400 rpm, Neutral Very Low (NVL) is commanded when N1 (Neutral) is the selected
range. NVL is achieved by turning D solenoid “on” in addition to E solenoid being “on,” which
locks the output. Otherwise, D solenoid is turned off in N1 (Neutral).
