Hi to All, one would never imagine there Lincoln ever having a problem, LOL, here is what happen to mine, a big clunk in the trans, felt like I rolled over a log, lasted that quick, pulled over, no sign of problem, other than the plastic clip that holds the shroud dn on the engine cover popped out and the other loosen. Talk to the dealer and they wanted it for a few days & have one of there mechanics drive it back & forth to work and see if they could duplicate it. That's not going to happen, when I drive it all over myself and it never happens. Anyone else ever have this issue? 2011 mkx with 52,ooo miles, premium trim package.
