So Friday I was driving home in the interstate and about 4 miles from home my 00 SE bogs down, chugs, and blows a cloud of smoke out from below the car, the rpms jumped to 4k and the car seemed in limp mode. I had p1320 flash just a week prior so I figured misfire...idk..got home and out car in reverse and Nothing..put in neutral and got nothing but loud clicking and the car wouldn't roll..so i put in drive and do a u-turn into driveway. When I put it in park the loud clicking noise came back and smoke was come from the hood. When looking under the car I found that the passenger output seal on the transmission blew out. WTF! Ok, so I go through the long process of pulling the axle and replacing that damn seal. I've topped the transmission fluid off(only use asmoil) and levels read fine but still no reverse, can't roll in reverse, front tires spin when front end is jacked up and in park, and now is showing p0744...how screwed am I?

 

Sorry wrong section..
