I used to be a lube tech in a different life 15 years ago and would occasionally see vehicles without dipsticks. Like you said the German brands like BMW and Mercedes but also Chrysler vehicles like the 300 and Magnum had a tube for the transmission dipstick but no dipstick inside of it just a cap on the tube.

At that time, Chrysler was owned by Daimler and shared a lot of stuff with Mercedes.
The NAG1 transmission some 300s used in Europe at least, is in fact the venerable Mercedes 722.6
That transmission was used in the US as well, before they switched to a ZF trans.
