They have a tool they use to check the fluid level from a plug in the pan, or there is a plug in the side of the transmission which is used much like a standard transmission has.
If there is a dipstick tube but no stick, there is a tool you can get from the dealer that will bottom out on the pan that will let you know the fluid level. Here is a diagram (below) of what it looks like.
Here is the instruction from the book
Verify that the vehicle is parked on a level surface.
Remove the dipstick tube cap.
WARNING: Risk of accident from vehicle starting off by itself when engine running. Risk of injury from contusions and burns if you insert your hands into the engine when it is started or when it is running. Secure vehicle to prevent it from moving off by itself. Wear properly fastened and close-fitting work clothes. Do not touch hot or rotating parts.
Actuate the service brake. Start engine and let it run at idle speed in selector lever position "P".
Shift through the transmission modes several times with the vehicle stationary and the engine idling
Warm up the transmission, wait at least 2 minutes and check the oil level with the engine running. Push the Oil Dipstick 9336 into transmission fill tube until the dipstick tip contacts the oil pan and pull out again, read off oil level, repeat if necessary.
NOTE: The dipstick will protrude from the fill tube when installed.
Check transmission oil temperature using the appropriate scan tool.
The transmission Oil Dipstick 9336 has indicator marks every 10mm. Determine the height of the oil level on the dipstick and using the height, the transmission temperature, and the Transmission Fluid Graph, determine if the transmission oil level is correct.
Add or remove oil as necessary and recheck the oil level.
Once the oil level is correct, install the dipstick tube cap.
