I noticed some stuff wrong with it... I smelled a burning smell while I was driving and a minute when I was idling... When i go down hills no matter what size my car makes a loud whining up noise and I press the gas down fast and it stops I need to service the transmission

More then likely this is a steal belt issue with the CVT transmission so we need to start with changing the fluid. This video shows the job being done on a similar car but the process is the same.

Here is a guide to help you step by step with instructions in the diagrams below to show you how on your car.

If this does not solve the issue then unfortunately we will need to replace the unit as the steal belt is slipping. Once it starts slipping it normally is easier and cheaper to just replace the unit. Below is the process to change the fluid. Let us know if you have questions. Thanks
