Fill Tube Plug Method
WARNING: This page is about a different car, the 2016 Cadillac CTS. However, it is still accessible from the selected car via links, so may be relevant.
- Based on accessibility, transmission fluid may be added through the fluid fill tube plug assembly (1) hole or through the oil level check plug (2) hole in the bottom of the transmission fluid pan.
CAUTION: Use Dexron® HP transmission fluid only. Failure to use the proper fluid may result in transmission internal damage.
- Clean around the fluid fill tube plug (1).CAUTION: Before removing the transmission fluid fill tube plug assembly, thoroughly clean around the plug to prevent dirt or contaminants from entering the transmission 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.
- Unlock the fill tube plug by lifting the plunger. Once the plunger is lifted, remove the entire plug assembly (1).
NOTE: It may be necessary to use a long pair of 90 degree needle nose pliers to lift the plunger and remove the plug assembly.
- 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 transmission fluid level and condition check procedure.
- Using the DT-45096-40 transflow oil fill adapter (1) and the DT-45096 flush and flow test tool (2) or a suitable hand pump, add transmission fluid through the fill tube plug opening. Refer to Transmission Fluid Cooler Flushing and Flow Test for complete DT-45096 flush and flow test tool operating instructions. Use the FLOW position on the main function switch to pump the fluid.
- Check the fluid level. Refer to Transmission Fluid Level and Condition Check CAUTION: 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. Overfilling will result in possible damage to the transmission.
