Having issues with our 2012 with the 2.0 ecoboost. It started shuddering/slipping while accelerating. It's most noticeable at highway speeds. I'm going now to change sparks plugs but I am wondering if it could be a CV axle. I'm not hearing any popping or clicking though. 95,xxx miles. Any thoughts?

 

Transmission? You've replaced the fluid?

 

If it really is slipping on acceleration, it's not plugs or CV joints. Start thinking tran$mi$$ion.
