Transmission Fluid Fill Procedure

Automatic Transmission - 10L80 MHS MQC | Diagnostic Information and Procedures | Document ID: 4974941 DT-45096 Transmission Oil Cooling System Flush and Flow Test Tool DT-45096-30 Transmission Cooler Flush Adapters DT-45096-40 Transflow Oil Fill Adapter DT-51190 Transmission Fluid Fill Adapter Equivalent regional tools: Special Tools

Caution

For all 10 speed RWD transmission applications, use ONLY Dexron ® ULV transmission fluid. Failure to use the proper fluid may result in damaging the transmission internally.

Warning

Check the transmission fluid level immediately after adding fluid and before vehicle operation. Do not overfill the transmission. An overfilled transmission may result in foaming or fluid to be expelled out the vent tube when the vehicle is operated, possibly causing a fire that may result in serious bodily injury or severe vehicle damage. Overfilling will result in possible damage to the transmission. Check the transmission fluid level, refer to Transmission Fluid Level and Condition Check. Case Plug Method

Caution

For all 10 speed RWD transmission applications, use ONLY Dexron ® ULV transmission fluid. Failure to use the proper fluid may result in damaging the transmission internally.

Note

The quart containers of Dexron® ULV must be shaken to stir up the additives before pouring. Do NOT use Dexron® VI or Dexron® HP. When the oil level check plug is removed with the engine OFF, transmission fluid may drain from the hole.

1. Based on accessibility, transmission fluid may be added through the side automatic transmission case plug (1) hole or through the top automatic transmission case plug (2).

Caution

Thoroughly clean around the transmission case plug to prevent dirt or contaminants from entering the automatic transmission case during plug removal. Use compressed air to dislodge any caked dirt that may be stuck on and around the plug area. Use a mirror to confirm the area is free of dirt before removing the plug. Failure to clean around the plug may result in transmission contamination causing possible transmission internal damage.

2. Clean around the automatic transmission case plug (1 or 2).
3. Determine the approximate amount of fluid needed to fill the transmission, based on the repair performed. Refer to Approximate Fluid Capacities. To avoid an under-fill condition, slightly overfill the transmission, and then allow the extra fluid to drain out through the oil level check plug during the tranmission fluid level and condition check procedure.

Note

The DT-45096 Transmission Oil Cooling System Flush and Flow Test Tool is being utilized as a convenient method to pump the fluid into the bottom pan. A suitable hand pump may also be used instead. When using the DT-45096 Transmission Oil Cooling System Flush and Flow Test Tool, monitor the display panel to determine the amount of fluid being pumped from the tool supply tank into the transmission.

4. Using the DT-45096-40 Transflow Oil Fill Adapter (1) and the DT-45096 Transmission Oil Cooling System Flush and Flow Test Tool (2), , add transmission fluid through the automatic transmission case plug hole. Use the FLOW position on the main function switch to pump the fluid.

Warning

Check the transmission fluid level immediately after adding fluid and before vehicle operation. Do not overfill the transmission. An overfilled transmission may result in foaming or fluid to be expelled out the vent tube when the vehicle is operated, possibly causing a fire that may result in serious bodily injury or severe vehicle damage. Overfilling will result in possible damage to the transmission.

5. Check the fluid level. Refer to Transmission Fluid Level and Condition Check.
