SERVICE PROCEDURE
1. Ensure the vehicle is on a flat and level surface. Apply the parking brake and block the
rear wheels. Ensure the vehicle will not move while performing the procedure.
2. Place an oil catch pan underneath the vehicle to collect draining ATF as each hose is
replaced (see Figure 1).

Figure 1

3. Loosen and slide all ATF hose clamps to the center of each hose (see Figures 2 and
3).

Figure 3 – 4HK1 5.2L Diesel

4. With the oil catch pan in place, remove one end of the hose and allow the ATF to drain
into the catch pan. When the ATF stops draining, remove the other end of the hose.
NOTE: Approximately 4-5 oz. (118–147mL) of ATF will drain during the service
procedure.
5. Slide two (2) new hose clamps onto the replacement hose (see Figure 4). The clamps
are held in the open position with factory installed lock tabs (see Figure 5). Install the
new replacement hose in the same location as the one that was removed. Every new
hose has colored dots or lines at each end to ensure correct orientation on the vehicle
(see Figure 4). Refer to Chart 1 to determine the orientation of each hose using these
markings. Push each hose onto the pipe until the blue or white band on the hose is
just over and beyond the bead on the pipe (see Figure 7). Push the hose onto the
radiator fittings until the hose will go no further.

6. Slide the hose clamps over the blue or white band and into position as shown in
Figures 6 and 7. Remove the lock tabs from the clamps to allow them to compress
onto the hose. Ensure that the hose clamps are not placed over the beads on the
pipes (see Figure 7). Adjust the clamps as necessary.

7. Perform Steps 4 through 6 for the remaining hoses.
8. Depress the brake pedal, start the engine, and move the shift lever through all gear
positions, returning to the “P” position. Inspect for leaks.
9. Connect IDSS and navigate to the transmission control module data list and check the
“Transmission Fluid Temperature (TFT) Valve Body” parameter (see Figure 8).

5

Figure 8

IMPORTANT: Failure to check and adjust the ATF level at the proper temperatures
will lead to over/under-filling of the transmission. Operating an automatic
transmission that has the incorrect ATF level can cause serious transmission
damage.
10. Remove the transmission level gauge and wipe off any debris/excess ATF with a clean
towel. Completely reinsert the transmission level gauge into the gauge tube and
remove it again. If the TFT value in IDSS is “COLD” 68°F-86°F (20°C-30°C), the ATF
level on the gauge should be within the “C” mark (see Figure 9). A preliminary
adjustment can be made here only if the TFT value is in the specified range. Once the
TFT value is in the specified range, wipe off any debris/excess ATF from the
transmission level gauge and securely reinsert it into the gauge tube.

Figure 9

IMPORTANT: If it is necessary to add ATF, only add Isuzu SCS Automatic
Transmission Fluid (ATF) or equivalent (p/n 2-90531-200-0) to the transmission.

11. Run the engine at a fast idle or drive the vehicle until the TFT is within the “HOT”
range 158°F-176°F (70°C-80°C).
12. Recheck the ATF level with the transmission level gauge which should now be within
the “HOT” range. Adjust if necessary (see Figure 10). Clean the transmission level
gauge and reinsert it into the gauge tube.

Figure 10

13. Turn the engine off and disconnect IDSS.
14. Unblock the rear wheels.
Proceed to Applying the Campaign Label section in this bulletin.
