In-Vehicle Fluid Change/Flush
IN-VEHICLE FLUID CHANGE/FLUSHIf the transmission or transaxle is contaminated with burned oil or clutch and band material, all fluid, including the fluid in the torque converter, must be changed and the transmission flushed out. Drain and replace the old fluid and use the following procedure to flush the assembly.
1. Disconnect the transmission oil cooling lines at the radiator heat exchanger.
2. Block the transmission oil return line. Connect a rubber line to the disconnected transmission oil "out" line and place the rubber line into a suitable oil drain pan.
3. Start the engine and allow the vehicle to run at idle in "PARK." Oil will now be discharged out of the transmission oil cooler line.
4. Place a filler funnel into the transmission filler tube and slowly fill the transmission with new automatic transmission fluid. Replace the fluid at approximately the same rate that it is discharged out of the oil cooler line. This will be about 3 or 4 quarts per minute.
CAUTION: DO NOT ALLOW THE TRANSMISSION TO RUN OUT OF FLUID. DAMAGE TO INTERNAL COMPONENTS COULD RESULT.
5. Run the engine and allow the flushing process to continue until the fluid discharged out of the oil cooler line is clear. This will require a total of about 7 quarts of fluid flushed through the system.
6. Stop the engine and perform the Oil Cooler/Heat Exchanger Cleaning Procedure.
7. After the flushing is completed, re-connect the oil cooler lines. Restart the engine and check for transmission fluid level. Refill as necessary.
