Mercedes dealers have been suctioning the oil out for nearly 30 years. Haven’t used dipsticks for 15+ years.

Wow . . . .

No trans dipstick on my 21 Tahoe, as I found out after looking for it for an extended period of time.

No trans dip sticks on many GM's since the mid 2000's. We had an 02 Passat without one too. Crazy crap been going on for years with manufacturers attempting to keep the owner from performing maintenance. As long as there's a fill cap, I'll find a way to drain them.

I drive less than 3000 a year so I have my oil changed in April and November.
