I DO NOT KNOW IF THIS CAP IS TO MAKE AN AIR-TIGHT SEAL WITH THE TUBE. Sealed-for-life automatic transmissions and hydrostatic drives are common these days. I have a sealed transmission on a hydrostat lawnmower going strong after 20-plus years of use.
Why are you quoting me/barking at me? I didn't ask the question.
I agreed with the mechanics that it was a good idea not to mess with the transmission. I suggested he refer to his owner's manual. He could also download a service manual from the link I posted.
Sealed for life, doesn't mean lasts for ever. The transmission fluid has to be checked and at some point will need to have some more added.
By the way, the cap is locked to keep regular people from checking their transmission fluid. This way Chrysler could charge a ton of money to do something that you could do yourself.
You can get an aftermarket dipstick and a replacement cap for less than $30.00.
