As of right now my car sits in the garage with a big pan under it because it's puking it's guts all over the floor. I've determined that the front pump seal needs to be replaced as that's where it looks like the leak is coming out of, the pan is dry. I have a few questions regarding this. 1. Do I have to pull the entire transmission out to replace this seal? 2. How hard is it to replace this seal? any tools I need or a write up I can follow? I wanted to put this off/not do it at all because I plan to replace everything, but my car has been dying lately when put into drive, but idles without issue when in park, do you think it's possible the car idles at too low of an RPM because the tranny is low on fluid and causing more friction?
