RECOMMENDED FLUID
| CAUTION | Use of fluids other than manufacturer recommended fluid may cause deterioration in shift quality and/or torque converter clutch shudder. |
Manufacturer recommends Mopar® ATF+4, Type 9602 fluid.
Mopar® ATF +4, Automatic Transmission Fluid when new is red in color. The ATF is dyed red so it can be identified from other fluids used in the vehicle such as engine oil or antifreeze. The red color is not permanent and is not an indicator of fluid condition. As the vehicle is driven, the ATF will begin to look darker in color and may eventually become brown. This is normal. ATF+4 also has a unique odor that may change with age. Consequently, odor and color cannot be used to indicate the fluid condition or the need for a fluid change.
OIL COOLER FLUSHING
| CAUTION | Whenever a transmission failure is present, oil cooler must be flushed. Torque converter must be replaced. Some models may have an external oil cooler mounted in front of radiator. This oil cooler must be flushed along with oil cooler mounted in radiator. See appropriate OVERHAUL article. |
Note. Manufacturer recommends Cooler Flusher (6906) for flushing oil cooler. Use only petroleum-based flushing solvents. Do not use solvents containing acids, water, gasoline or any other corrosive liquids.
- Note oil cooler supply and return lines. Remove cover plate filler plug on cooler flusher. Fill reservoir 1/2 to 3/4 full of fresh flushing solution.
- Reinstall filler plug. Ensure pump power switch is in OFF position. Connect Red alligator clip to battery positive, and Black alligator clip to chassis ground. Disconnect oil cooler lines at transmission. NOTE: Always reverse flush when flushing oil cooler and lines. Converter drainback valve must be removed and an appropriate replacement hose (supplied with Cooler Flusher 6906) installed to bridge space between transmission cooler line and cooler fitting. Failure to remove drainback valve will prevent reverse flushing.
- Connect Blue pressure line to outlet oil cooler line. Connect Clear return line to inlet oil cooler line. Turn pump on and flush oil cooler and lines for 3 minutes.
- Monitor pressure reading and Clear return line. Check equipment manufacturer's instructions for pressure specifications. If solvent flow is intermittent or exceeds specified pressure, replace oil cooler(s).
- Turn pump off. Disconnect Clear suction line from reservoir at cover plate. Turn pump on for 30 seconds to purge flushing solution from oil cooler lines. Turn pump off.
- Place Clear suction line into a one quart container filled with ATF. Turn pump on until all fluid is removed from container. This removes remaining flushing solvent from oil cooler lines. Turn pump off.
- Disconnect alligator clips from battery and ground. Remove flushing adapters from oil cooler lines. Reconnect oil cooler lines. Fill transmission to proper fluid level with ATF. See «CHECKING FLUID LEVEL»(ref-170037-S22516546192004122800000) under LUBRICATION.
