The car dealership where I get my oil changed told me the other day that I had developed a couple leaks on my car. One of them was a transmission pan leak, easy enough fix, right?
So I had some free time on my hands last night, so I decided I was gonna change the transmission filter, and gasket, since I'm 95% sure the leak was just from a bad gasket. So I jack the car up in the front, stuck a jack stand under there as well (safety first), and roll on under laying on the creeper. While I was under there unscrewing all 800 bolts that hold the transmission pan on (what a PITA BTW), I started to notice things getting slightly "snug", but I just thought it's cuz I was rolling further back under the car. Well a few seconds later, I noticed it started getting REALLY snug under there, to the point where I had to slightly struggle to get out from under the car.
Apparently what had happened was that the jack was slowly letting the vehicle down on top of me. I hadn't raised the stand up high enough initially I guess, but it was raised high enough to where it did stop the vehicle from coming down on top of me and crushing me. That scared the living bajesus out of me. I was thanking my lucky stars afterwards.
On the plus side, changing my filter really seems to have helped. It no longer bangs into Drive, and doesn't have a hard drop in RPM's as I'm cruising from 30-50. I was not expecting that at all. My old one must've been plugged up pretty bad or something.
So take note kids: Always use jack stands! You never can tell when a jack is going to fail, and crush you!
