Hi there. It would appear there is a combination of problems happening with your vehicle. First, the transmission fluid and engine oil leak(s) need to be addressed. The fluid loss may account for the burning smell. The Check Engine Light on leads me to believe the ECM (engine control module)/computer has recognized the drivability (lack of power) concern.

Accessing the computer for codes may help direct the diagnoses. There are many possibilities for a lack of power, low fuel pressure, restricted exhaust, a faulty throttle position sensor, mass airflow sensor, etc.

Assuming, there is the change engine oil soon light, may be due to the light was not reset at the time of service. The noise you are hearing could be any number of things while driving. I recommend having your vehicle’s lack of power issue and other concerns diagnosed and repaired by a certified technician, such as one from YourMechanic.
