So, still haven't been able to get around to fixing the O-Ring leak. Tomorrow will be the day, hopefully, if it isn't too darn cold. Otherwise I am just going to see if I can go to the shop and have them do it next week.

Though, not sure if this is related to the leak, but I was going for a drive last night, and was going up a steep hill. I was going about 20-30ish MPH (can't exactly recall, speed limit was 25 though), and near the top of the hill, my car started revving very high (about 6000 RPMs), like it was having a hard time getting at the top. Not sure if it was lack of power from the motor itself, or if it had anything to do with the transmission not sliding into 2nd gear properly. This is the first time I experienced this, and it didn't happen again since.

My car does have the ABS light on. Sometimes my car will vibrate pretty bad. I can't tell, sometimes I swear it's my transmission, other times the vibrating randomly happens, after the car shifts gears. It's only when I speed up. Anyone know what's going on?
