One problem related to transmission fluid leaking has been reported for the 2001 Chevrolet Blazer. The most recently reported issues are listed below.
Transmission cooler lines between the radiator and transmission are corroded and pitted. The lines are installed over the exhaust catalytic converter. There is transmission fluid leaking from the lines, which is dripping onto hot exhaust components and burning, creating a fire hazard. These lines appear to be stainless steel, which shouldn't be corroding. The lines should not be in such close proximity to exhaust components. When the vehicle is not running/in motion, transmission fluid pools on the ground under the vehicle. In motion, the fluid is being blown rearward, coating the undercarriage and exhaust.
