cmax-nynj Posted June 17, 2018 Report Share Posted June 17, 2018 (edited) Above are what I saw when I tired to change the oil today. I saw one drop of red fluid hanging from the metal. The leak isn't too severe because the removable plastic underneath it is dry. It seems the rear main seal is leaking a tiny bit but the drop of oil suggests it is leaking transmission oil. Is this supposed to fall under the 8yr/100K Hybrid component warranty? I also have GEICO 's mechanical breakdown coverage but not sure if this applies.

Andy T Posted March 16, 2020 Report Share Posted March 16, 2020 I had the rear main seal go out on my 2014 C-Max Energi SEL with around 68,000 miles just outside of warranty. The dealership stated that the rear main on the C-max is not a seal but rather some kind of sealant requiring the entire engine/transmission to get pulled, cleaning up the area, and reapplying more sealant to the same surface before reassembly. I can't see investing $1800 in fixing a seal that failed 68,000 miles into operation with the same poor design and hoping for different results. I really love the car but can't justify the expense to correct Ford's poor engineering choice. Does anyone know of a more permanent fix (i.e. some sort of after market gasket) that will more permanently fix the issue? Quote Link to comment Share on other sites More sharing options...
ptjones Posted March 16, 2020 Report Share Posted March 16, 2020 That is weird, I have 247k miles on my Hybrid with no problems. Sounds to me like something was make out of spec causing a problem. Paul Quote Link to comment Share on other sites More sharing options...

Removing the engine / transmission is, IIRC, about 10.6 hours of labor. You could likely find a non-Ford shop to do it at less. There is a TSB on this. See TSB 15-0174. Are you sure that your transmission isn't failing? Are there any unusual noises when the transmission is spinning? See TSB 18-2328. The transmission transfer shaft can bore a hole in the engine side damper cover causing transmission fluid to leak into the damper housing and thus leak out. https://ford.oemdtc.com/1036/transmission-fluid-leak-at-the-damper-housing-2013-2014-ford-lincoln https://static.nhtsa.gov/odi/tsbs/2018/MC-10148717-9999.pdf Edited March 17, 2020 by Plus 3 Golfer Quote Link to comment Share on other sites More sharing options...
