on a 2010 Camaro..

There is no dipstick/filltube.. Level is checked at the drain/fill plug on the pan..Maint schedule I think says at 50K.. Use Dexron VI transmission fluid only. Failure to use the proper fluid may result in transmission internal damage. From service manual Caution: THE ENGINE MUST BE RUNNING when the trans oil level check plug is removed or excessive fluid loss will occur, resulting in an under-filled condition. An under-filled transmission will cause premature component wear or damage. Note: Continue to monitor the TFT. If the TFT is not within the specified values, reinstall the trans oil level check plug and repeat the previous steps. Remove the trans oil level check plug (1) from the transmission fluid pan. Allow any fluid (2) to drain. If the fluid is flowing as a steady stream, wait until the fluid begins to drip. If no fluid comes out, add fluid until fluid drips out. Refer to Transmission Fluid Fill Procedure (See: Service and Repair). Inspect the fluid color. The fluid should be red or dark brown. If the fluid color is very dark or black and has a burnt odor, inspect the fluid and inside of the bottom pan for excessive metal particles or other debris. A small amount of "friction" material in the bottom pan is a "normal" condition. If large pieces and/or metal particles are noted in the fluid or bottom pan, flush the oil cooler and cooler lines and overhaul the transmission. If there are no signs of transmission internal damage noted, replace the fluid filter assembly, repair the oil cooler, and flush the cooler lines. Fluid that is cloudy or milky or appears to be contaminated with water indicates engine coolant or water contamination. Refer to Engine Coolant/Water in Transmission (See: Symptom Related Diagnostic Procedures\Engine Coolant/Water in Transmission). Caution: Refer to Fastener Caution (See: Service Precautions\Vehicle Damage Warnings\Fastener Caution). Replace the trans oil level check plug and tighten to 25 Nm (18 lb ft) . Inspect for external leaks. Refer to Fluid Leak Diagnosis (See: Component Tests and General Diagnostics\Fluid Leak Diagnosis). Reset the oil life monitor only if the fluid was changed.
