I'm pretty new to auto repair and mistakenly ordered and installed manual transmission cv axles on my 2012 Mazda 5 with an automatic transmission. They installed correctly. I even had a repair show check my work and everything looks right. Test driving after the installation found an unusual vibration when accelerating and climbing hills, like an entrance ramp to the highway.

Is there any difference between the manual and automatic transmission cv axles that would cause this issue? Should I replace the manual with automatic cv axles?

Thanks for your replies
