Strong transmission fluid smell inside the car
My car has 170000 miles.
My car has an automatic transmission.
Hi Marg. Thanks for sending the question tonight. Most of the time, a transmission fluid leak is caused by either a bad transmission pan gasket or a loose or frayed hydraulic line. The smell being inside the car is likely due to the vents being open - but does indicate a rather serious issue that should be inspected by a professional mechanic to diagnose and repair.
