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.
