Ok, I found that the speed sensor to the tranny had leaked some tranny fluid onto the cats and fixed the leak. I did that today and wiped off as much fluid as I could. The problem is that the cats are smoking when I shut the car off. It seems to be coming from between the heat shield and the cat itself. The car does run alittle rich and am still working on that. Did a search but wanted some type of time frame on when the tranny fluid should burn off?? Maybe Im worried about nothing.
