In attempts to fix my car's persistent acceleration problem, I am going to be swapping out the transmission with one I got from the junk yard that has 117k miles on it. While it is out of the car, is there anything I should pay special attention to (Seals, solenoids, etc.)? I want this to go seamlessly as possible. Also, any recommendations for how to do the trans swap? I plan to drop it out through the bottom.
