Then, no one will be thinking with their Dipstick, Jimmy...
There is no real or ideal thing as a sealed transmission, especially a Chrysler one. There is always a way to maintenance the transmission, even on those so-called sealed ones. This goes all the way back to the 2001 (down to 1996?) Sunfire, they only had a cap as well. Some also claimed they ARE sealed. Chrysler would have some real arrogance to seal their automatics, they can't have that much confidence in them. The people with the sunfires, you could remove a hex nut that was above the transmission pan, and add fluid.
The only automatic transmissions, that work the way they are supposed to, that probably would not need any maintenance the LIFE of the CAR, would be the CVT.
