Bucking while driving.

[silverflash]

Have noticed a sort of bucking while driving. Doesn't matter in sport mode or drive. But if my foots on the gas it seems to do it. I tried driving it with sport mode and shifting gears and zero issues. Only seems to do it when it shifts on its own. Seems like it's either shifting then bucking in-between or just having a misfire. No lights. 2500 miles. 21 fx4.

Lots of posts about this lately. Is it humid where you are? Wonder if it’s the condensation in the intercooler that affects ecoboost motors.

As an experiment I laid into herin sport mode from a stop and got to 60 pretty quick and every shift was smooth and perfect. Perhaps these just don't like easy driving? And it is humid here but not crazy. And not too hot- mid 70s. Mountains.

This is beginning to feel like some kind of coup by the “Fuel in oil” people since that topic has kind of fizzled out.

Yep-cuz we needed a transmission that does that.
