Install the jumper wire.
• For population A only → To install the gauge AG001, locate the jumper coming from the main harness
behind the panel, and connect it to the back of the gauge. See Fig. 7.
• For populations B-E → To install the gauges AG002 or AG003, check if a spare jumper is attached to
the adjacent gauge, and connect it to the gauge that is just installed. If the jumper is missing, install
the jumper supplied between the adjacent gauge and the newly installed gauge. See Fig. 1 and
Fig. 7.

SF684 F-I – Installation of the Transmission Gauge
1.

Check the base label (Form WAR259) for a completion sticker for SF684 (Form WAR261), indicating this
work has been done. The base label is usually located on the passenger-side door, about 12 inches (30
cm) below the door latch. If a completion sticker is present, no work is needed. If a completion sticker is
not present, proceed to the next step.

2.

Park the vehicle on a level surface, shut down the engine, and set the parking brake. Chock the tires.

3.

Disconnect the batteries at the negative terminal.

4.

Remove the upper-center fascia panel. See Fig. 8.

NOTE: The specified gauge locations for the vehicle being repaired, based on the vehicle populations, are listed in
Table 3, page 4.
NOTE: To protect the panel and to assist in marking the gauge location, it is recommended to use masking tape
on the panel areas where layout lines and centerline marks are to be made.
NOTE: Digital calipers are recommended to measure and lay out the distances from the top edge of the panel
to the horizontal lines, and from the center of the upper panel notch to the vertical lines. To ensure accuracy
while marking vertical lines in relation to the horizontal lines measured from the top edge of the panel, it is advisable to use a small drafting square.
14.

Mark the location of the gauge centerline and the center of the gauge clocking notch to be installed, per
the dimensions shown in Fig. 14.

NOTE: In this campaign, no vehicles require a transmission temperature gauge to be installed in the position
AU007. Some vehicles may have a different gauge installed in the position of AU0007. Position AU007, shown
in Fig. 1 and Fig. 14, is for reference only.
15.

Drill out the holes for the gauge installation. See Fig. 15.
15.1 Centerpunch the marks made for the gauge centerline and the gauge clocking notch centerline.
15.2 At the gauge clocking notch centerline, drill a 5-mm hole. Use a 13/64-inch drill bit if a metric bit is
not available.

NOTICE
Ensure that the bit does not plunge too deep and damage the wiring behind the panel.
15.3 At the gauge centerline, drill a 53.1-mm hole. Use a 2-1/16-inch hole saw suitable for aluminum if a
metric bit is not available.

To install the gauges AU004, AU005, AU006, or AU007, check if a spare jumper is attached to the adjacent gauge, and connect it to the gauge that is just installed. If the jumper is missing, install the jumper
supplied between the adjacent gauge and the newly installed gauge. See Fig. 1 and Fig. 17.
