Note

•  Prior to filling the SST with clean ATF, make sure that the canister is clean.

4.  Fill the SST with clean ATF.

•  Connect the open end of the fluid hose from the SST (49 UN30 7D4650) to the SST (49 UN30 7437) at the bottom of the fluid pan.

7.  Apply a maximum of 206.85 kPa {2.11 kgf/cm², 30.0 pis} to the open end of the vacuum/pressure hose from the rubber tip air nozzle. Fluid will immediately start flowing out of the SST into the fluid pan.

8.  Add 1.89—2.83 L {2.00—2.99 US qt, 1.67—2.49 imp qt}of ATF into the fluid pan. Stop the process by releasing the air pressure and removing the air nozzle from the end of the hose.

9.  Connect the M-MDS to the vehicle DLC-2 16-pin connector.

10.  Verify the ATF temperature using the PID/data monitor “TFT”.

11.  Warm up the automatic transmission until the ATF temperature is 27—49 °C {80—120 °F}.

12.  With the engine running, inspect the ATF level in the SST.

•  If the fluid drains back into the canister, the transmission is full.

•  If no fluid drains back, more fluid will need to be added. Repeat Steps 7 and 8.

13.  Once the transmission is full, place a hand vacuum pump on the open end of the vacuum/pressure hose on the SST and apply vacuum to the system. This will pull out any extra fluid trapped in the system and direct it into the container.

14.  Allow the ATF to drain.

•  When the ATF comes out as a thin stream or drip, the ATF is at the correct level.

15.  Install the small (center) fluid level indicating plug.
