2014 Expedition Limited, Tow package, 70k miles, one owner (Me), Medium workload, 3% of use as tow vehicle. I am a 65 year old mechanic, engineer and Ford owner since 1980, all of my earlier vehicles were GM products.
The issue is a noise that popped up recently. the noise seemed like a chatter that emanated from the transmission. The sound would happened at start-up and low speed loading, moving from stationary to 5MPH. The sound was similar to that of a pilot bearing chatter, or transmission stall (Gear ratio too low). Putting the transmission in "Tow Haul" which turns the overdrive off seemed to reduce or eliminate the noise, which lead me to look at an issue with the overdrive.
At 70,000 miles I had concerns about the transmission since there was no normal user dipstick. I found the stub dipstick and found that it's not all the difficult to work with and for the most part keeps the transmission safe from those that overfill. While under the vehicle I looked for anything lose that might actually be the noise like the catalytic converter heat shields, but they were solid, nothing obvious was lose. I checked my fluid level, idling in park, transmission hot, and found the level to be one half inch below the "A" mark on the dipstick. I made a funnel tool that included a graduated clear funnel that necks down to a 3/8" id ridged tube that extends from the top of the engine (Hood open) to the filler hole where the stub dipstick is located. I poured the fluid in increments so as not to over fill, where my target was between "A" and "B" on the stub dipstick, making certain that the dipstick was fully seated between dips. The total amount of transmission fluid (Mercon LV) added is approximately 465 milliliters or almost half of a quart. I noted that the color of fluid on the dipstick matched that of what I was putting in. I am not sure where the fluid goes since there are no leaks but after 70K miles, it be lost in coating, evaporation, mysteries of the machine and certainly the minute amount that makes it past a seal to keep the seal from burning up. So I top off the transmission, start it up and test: The noise is still there!
I researched more about "2014 Expedition overdrive noise" and found a host of things, again but one thing stood out, and yes the post was on this site (Thank you Expy Forum Contributors). There is a crossover exhaust pipe that is just out of sight near the transmission and on it is a heat shield missing one band! My $6,000 dollar worry went to $1.75 for a stainless steel hose clamp. FIXED!!!
Thank you friends, I hope this helps someone.
