LUBRICATION
Note. For additional information, see appropriate AUTOMATIC TRANSMISSION SERVICING article in TRANSMISSION SERVICING.
RECOMMENDED FLUID
Note. The use of Dexron II transmission fluid is not recommended by manufacturer. Clutch chatter may occur when this type of fluid is used.
Manufacturer recommends Mopar(R) ATF+3, Type 7176 fluid.
OIL COOLER FLUSHING
| CAUTION | Whenever a transmission failure is present, oil cooler(s) must be flushed and torque converter 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. Flush oil coolers separately. DO NOT attempt to flush both oil coolers at one time. |
Note. Manufacturer recommends Cooler Flusher (6906) as the only suitable procedure for flushing oil cooler. Use only petroleum-based flushing solvents. DO NOT use solvents containing acids, water, gasoline or any other corrosive liquids.
Flushing Procedure
Note. ALWAYS reverse flush when flushing oil cooler and lines.
- Note oil cooler supply and return line locations. (Scheme 13) 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.
- 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 Clear return line and pressure reading. Pressure reading should stabilize at 20 psi (1.4 kg/cm 2 ) if equipped with a single oil cooler, or 30 psi (2.1 kg/cm 2 ) if equipped with dual oil coolers.
- 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 appropriate fluid. See «LUBRICATION»(ref-40647-S22994746382000010700000).
