Diagnostic Codes
Diagnostic codes are numerical indications relating to
a malfunction in transmission operation. These codes
are logged in the TCM/ECU memory. The most se-
vere or most recent code is listed first. A maximum of
five codes (numbered d1-d5) may be listed in
memory at one time. If the mode indicator LED is
illuminated, the displayed code is active. If it is not
illuminated, the displayed code is not active.
NOTE: During normal operation, an illuminated
mode indicator LED signifies the specialized
mode operation is in use.
To enter diagnostics mode, first park the vehicle and
apply the parking brake. Then simultaneously press
both the up and down arrows twice.

General Information, Straight-Shift
Eaton Fuller 5-speed FS models are fully synchro-
nized. They have five forward speeds and one re-
verse. See
for the shift pattern.
Eaton Fuller 6-speed FS and FSO models are fully
synchronized. They have six forward speeds and one
reverse. See
for the shift pattern.
Eaton Fuller 7-speed T models are not synchronized.
They have seven forward speeds and one reverse.
See
for the shift pattern.
These transmissions are designed for use with on-
highway, fuel economy engines where a minimum of
shifting is desired and less gear reduction is accept-
able.
Operation, Straight-Shift
1.
Always use first gear when starting to move the
vehicle forward.
IMPORTANT: Do not rest your foot on the clutch
pedal while driving. This causes partial clutch
disengagement which could cause premature
clutch wear.
2.
On synchronized models, press the clutch pedal
to the floor when shifting gears. Double-clutching
is unnecessary.
On unsynchronized models, press the clutch
pedal to the floor to contact the clutch brake only
when engaging the first or reverse gears.
