^ Battery monitoring distinguishes four ranges (U = battery voltage):

1) U less than 7 volts go to transmission goes into limp home mode
2) U 7.. 9 volts = gear is held for about 2.5 seconds, if U is still in this range afterward, transmission goes into limp home mode
3) U 9... 16 volts = voltage is O.K.
4) U higher than 16 volts = transmission goes into limp home mode
