TRAN SYS FAULT Message -- OUT1 SPD FREQ
This fault message will be displayed if the control recognizes a speed signal
from the transmission output speed sensor that is zero when the transmission
is in gear, and there is an input speed signal. Shifts from neutral to forward will
be inhibited based on the transmission input speed. The display message will
not be cleared until the fault is corrected and the controller is repowered by
cycling the key switch.
The likely cause of this problem is a transmission output speed sensor that is
out of adjustment or damaged. The sensor is located near the output shaft of
the transmission. The sensor can be adjusted as follows.
A. Remove the output speed sensor.
B. Thoroughly clean the output speed sensor or replace if damaged.
C. Align the gear seen through the output speed sensor hole so the gear
tooth is in the middle of the hole.
D. Screw the output speed sensor into the hole until it just contacts the
gear tooth.
E. Back out the output speed sensor 1/4 to 1/2 turn. *
F. Use jam nut to lock the output speed sensor in place (50 in-lbs, 5.7
Nm).
* Transmission Input Speed and Output Speed Sensor.
1/4 to 1/2 turn gap corresponds to approximately .016 to .032 in.
air gap between the speed pickup tip and the top of the gear
tooth.
