NHTSA complaint #10885905, filed 2016-07, 182,000 miles“A/c condenser and transmission unit. A freon leak in this unit can dump freon gas and compressor oil into the transmission which can cause trans problems or transmission fluid can leak into the A/C system and ruin all components in the system. This can be a very expensive repair or the car is junk. Trans cooler should be a separate unit to prevent this problem.”
