Jeep Commander begain whining on acceleration. Car shifts rough in first gear. Check engine light in and out. What could we be dealing with here?

Most likely you have a bearing going out on either the serpentine belt tensioner, a idler pulley or on one of the components that is driven by the serpentine belt.

But get those codes read and post them here. It may give us more of a clue.

The codes are p0700, p0732,p0733, and we replaced both speed sensors, and the transmission pressure sensor, oil smells burnt. 😕
