My GF owns a 2008 300 (3.5L), the transmission pan is leaking oil and when in reverse the trans slips sometimes. I worked at an oil change tranny shop about 20 years ago, did 100's of trans tunes (filter gasket, straighten pan oil, etc). I cannot find a trans dipstick or even a filler tube for this tranny. WTF?

I see that there is some special "miller tool" for checking fluid level, but this tranny does not even have a fillet tube from what I can see.

Couple of questions:

1) I don't have my GF's owners manual in front of me, what type of trans fluid to I need to get, and when the pan is off, filter is changed, how much fluid goes back in?

2) Where do I refill the fluid once the filter, pan & gasket have been replaced? (I looked quick last night in the dark for a place to refill, maybe I missed it), and does anyone know how much fluid goes back in after a trans tune? Since there is no dipstick.

I think Chrysler are a bunch of a-holes for removing the dipstick. Because a few ppl can't use the correct fluid, none of us can service the tranny's, yeah, that makes a lot of sense...

 

u will need to know if U have A NAG or 42 RE trans for the rite filter
ATF+4 only There is no dip stik u can buy one off ebay only issue is i cant tell what the correct level is suppose to be with out a scanner telling you the temp of the fluid.

and FYI it was not Chrysler this is a Mercedes Benz design

 

Oh my....

Well, I'm having my GF take it to the dealer for a trans service, it's going to cost about 50% more than if I was going to do it, but I don't have the time to deal with this tbh.

I did buy the dipstick off of ebay, hoping that I can use it in the future. Are you saying there should be a filler tube somewhere behind the intake? Or does either of the NAG or 42 RE have no tube at all?

Thanks

 

the intake towards the back on pass side it will be in the middle of the intake a black round twist off cap that's the filler and dip stick location.

 

Dealer charged $280 for a filter, gasket and refill. (Oh, they decided they needed to put a new pan on, as they won't straighten the gasket surface of the old one, jeez...)

Yup, guess I should have left work early on Sat and done it myself...
