With Radiator In-Tank Transmission Oil Cooler
FLUSHING COOLERS AND TUBESWhen a transmission failure has contaminated the fluid, the oil cooler(s) must be flushed. The torque converter must also be replaced. This will insure that metal particles or sludged oil are not later transferred back into the reconditioned (or replaced) transmission.
1. Remove cover plate filler plug on Tool 6906B. Fill reservoir 1/2 to 3/4 full of fresh flushing solution. Flushing solvents are petroleum based solutions generally used to clean automatic transmission components. DO NOT use solvents containing acids, water, gasoline, or any other corrosive liquids.
2. Reinstall filler plug on Tool 6906B.
3. Verify pump power switch is turned OFF. Connect red alligator clip to positive (+) battery post. Connect black (-) alligator clip to a good ground.
4. Disconnect the cooler lines at the transmission.
NOTE:
- When flushing transmission cooler and lines, ALWAYS reverse flush.
- The converter drainback valve must be removed and an appropriate replacement hose installed to bridge the space between the transmission cooler line and the cooler fitting. Failure to remove the drainback valve will prevent reverse flushing the system. A suitable replacement hose can be found in the adapter kit supplied with the flushing tool.
- This flushes the bypass circuit of the cooler only.
5. Remove oil cooler from vehicle.
6. Connect the BLUE pressure line to the OUTLET (From) cooler line.
7. Connect the CLEAR return line to the INLET (To) cooler line
8. Turn pump ON for two to three minutes to flush cooler(s) and lines.
9. Turn pump OFF.
NOTE: This flushes the main oil cooler core passages only.
10. Remove the thermostat from the oil cooler.
11. Install Special Tool Cooler Plug 8624 into the transmission oil cooler (Fig. 3).
12. Re-install the snap-ring.
13. Turn pump ON for two to three minutes to flush cooler(s) and lines.
14. Turn pump OFF.
15. Remove Special Tool Cooler Plug 8624 from the transmission oil cooler.
16. Install a new thermostat and snap-ring into the transmission oil cooler.
17. Install the transmission oil cooler onto the vehicle.
18. Disconnect CLEAR suction line from reservoir at cover plate. Disconnect CLEAR return line at cover plate, and place it in a drain pan.
19. Turn pump ON for 30 seconds to purge flushing solution from cooler and lines. Turn pump OFF.
20. Place CLEAR suction line into a one quart container of Mopar ATF +4, type 9602, Automatic Transmission fluid.
21. Turn pump ON until all transmission fluid is removed from the one quart container and lines. This purges any residual cleaning solvent from the transmission cooler and lines. Turn pump OFF.
22. Disconnect alligator clips from battery. Reconnect flusher lines to cover plate, and remove flushing adapters from cooler lines.
