1997 Chevy Blazer transmission problems

[joerdnr16]

I have had a 97 Chevy Blazer for about 4 months. It has about 150,000 miles on it. I am now having problems getting into third gear. First and second are just fine but as soon as third starts, it revs up. Also smoke comes out of the top. I tried to put in transmission fluid, and everything I put in goes straight out of the bottom. What did I break?

What do you mean by this? You put oil in the transmission and it just pours out? If this is the case, you have a leak and need to find where the leak is. From the sounds of it, take a close look at the tranny dipstick, and the rubber around it where it connects to the transmission. If the tranny is low on oil becasue of a bad leak, you could easilt damage it by driving it like this.
