rmhuntley Posted November 9, 2018 Report Share Posted November 9, 2018 I have a '13 c-max hybrid that was in an accident before I owned it. the trans casing is cracked and it weeps fluid. I was told by my dealer to check the fluid ever 1k miles or so and add as necessary. I went in today to get an oil change and have them top off the trans and was told that it was a sealed unit and therefore they cannot to it off. They were nice enough to quote me $15k for a new trans and installation..... I know that according to alldata you can top off the trans fluid, and there is certanily a drain plug, but I can't seem to find the fill/check plug(s). any assitance would be great.

rmhuntley Posted November 10, 2018 Author Report Share Posted November 10, 2018 Thanks. I appreciate it. now, is there a check plug to verify level? Quote Link to comment Share on other sites More sharing options...
plus 3 golfer Posted November 10, 2018 Report Share Posted November 10, 2018 The fill / check plug is one in the same. So, you fill until fluid overflows out the fill / check plug hole. obob and rmhuntley 2 Quote Link to comment Share on other sites More sharing options...

stratosurfer Posted April 15, 2019 Report Share Posted April 15, 2019 I used that vid above with the brown c-max this weekend and found it -very- difficult to find the fill plug. The drain is super easy. I would say this, it is on the backside of the transmission, and at an up-angle -facing- the firewall, close to the cat.I also found it -very- challenging to break it free. I cut a small piece of 1/2” pvc pipe I had to put on the Allen wrench as a small cheater-bar. Quote Link to comment Share on other sites More sharing options...
Lacienega Posted December 18, 2022 Report Share Posted December 18, 2022 Did you access the fill plug from the top or from underneath? According to ford you have to remove the air cleaner, air cleaner outlet pipe and cowl panel in order to get to it? Quote Link to comment Share on other sites More sharing options...

I used the check plug hole on the side as described here. Turn the wheels full left then reach in front of the left tire, pull up a mud flap and you can see it. A bit cumbersome but not that hard.
