I have a 97 legacy gt. last week when I was going down the interstate, I noticed smoke behind my car and pulled over. When I opened the hood,I noticed oil all over everything at the bottom back of the motor, by the tranny. I got it to the shop and they decreased it and drove it and couldn't find a leak anywhere. It appeared to be gear oil from the tranny and the fluid was a little low. I have drove it several times since and had no problem til the other day. Once again I was on the interstate, but this time for much longer, when once again smoke is pouring out of the back of my car. Same problem,gear oil blown all over and burning off. Have you ever heard of this happening?
