Hello all. I am trying to figure out how to get this charging tube cap off! My car has been sitting for about 6 weeks and there is a puddle under it, it appears to be tranny fluid, so I would like to check the level, I have heard of a way to do this with a long zip tie, and marking the cold and hot levels on the tie, but, I can't figure out how to get the cap off, seems you need some kind of tool?? It looks like it is a Mercedes Benz tranny, the cap says MB shop only, or something like that. Can anyone help?! or offer some tips??

 

Transmission dipstick cap

 

That worked perfectly!!

 

You can get the replacement locking pins fron a Mercedes or Chrysler dealer for under a buck.

 

There aren't really necessary, are they?

 

The portion of the old red clasp should be reinserted, and can later be removed with a small screwdriver...or you can use a new one. If you do not put any locking clasp back, the black cap might vibrate loose and contaminants will get in your transmission.

 

Didn't think about that, thanks!
