So I bought my 2008 caliber two months ago. It has a steadily worse grinding and whining noise only while accelerating that the dealership said is likely the cvt transmission. I purchased a powertrain warranty "through mazda". However the policy states it only covers up to the trade in value of the vehicle, so I'm not sure if a transmission repair "replacement" would even be possible, depending on the price. Does anyone know how much it cost to replace the cvt?
