E 450 V8-6.0L DSL Turbo VIN P (2004)
NOTE: The transmission fluid cooler line routing for this vehicle is slightly different than what is illustrated. The fluid cooler lines are routed over
the top of the transmission and run down the driver side of the vehicle. The remote filter is also in a different location It is mounted to the side of the
transmission over the top of the shift cable bracket.
CAUTION: Whenever the transmission has been serviced or a remanufactured transmission has been installed, the transmission fluid cooler lines and
the remote filter manifold must be cleaned and backflushed to remove any contaminants or transmission failure will occur.
CAUTION: A new oil-to-air (OTA) cooler must be installed to prevent foreign material from reentering the transmission. If foreign material reenters
the transmission, transmission failure will occur.
NOTE: This transmission is equipped with a remote transmission fluid filter. When carrying out an overhaul or installing a new or a remanufactured
transmission, a new filter element must be installed.
1. Using a suitable torque converter/fluid cooler cleaner, flush the transmission fluid cooler and lines.
2. Remove the remote filter element.
3. If equipped, remove the in-line fluid filter.
4. CAUTION: The transmission cooler lines must be disconnected prior to flushing out the cooler lines. Do not attempt to flush out the remote filter
housing or damage to the housing will occur.
Disconnect the four transmission fluid cooler lines at the remote filter housing.
5. Leave the transmission fluid cooler lines disconnected from the transmission case.
6. Disconnect both transmission fluid cooler lines from the OTA.
7. Discard the OTA if overhauling or installing a new transmission.
8. Flush each transmission fluid cooler line independently.
9. Connect the cleaner pressure and return lines correctly.
1. Connect the pressure line to fluid cooler inlet tube.
2. Connect the return line to fluid cooler outlet tube.
3. Place the outlet end of the return line in the fluid tank reservoir.
10. NOTE: Cycling the pump on and off will help dislodge contaminants in the cooler system.
Switch the pumps on. Allow the fluid to circulate a minimum of 5 minutes.
11. Switch the pump off.
12. Disconnect the cleaner pressure line at the fluid cooler tube.
13. Using compressed air, blow through the fluid cooler inlet tube until all fluid is removed.
14. Remove the rubber hoses from fluid cooler tubes.
15. Connect the cleaner pressure and return lines correctly.
1. Connect the pressure line to the radiator in-tank fluid cooler.
2. Connect the return line to the other side of the radiator in-tank fluid cooler.
3. Place the outlet end of the return line in the fluid tank reservoir.
16. NOTE: Cycling the pump on and off will help dislodge contaminants in the cooler system.
Switch the pumps on. Allow the fluid to circulate a minimum of five minutes.
17. Switch the pump off.
18. Disconnect the cleaner pressure line at the fluid cooler tube.
19. Using compressed air, blow through the fluid cooler inlet tube until all fluid is removed.
20. Remove the rubber hoses from fluid cooler tubes.
21. Flush the remote filter manifold and ensure that the small bypass orifice is free of debris.
22. Flush the remote filter housing and clean the magnet.
23. Backflush and then flush the radiator in-tank cooler.
24. Install a new remote filter element.
25. Install a new OTA as part of a transmission service or installing a remanufactured transmission.
26. Carry out the transmission fluid cooler flow test.
