I've just about 100,000 miles since my transmission was rebuilt. I was backing up a steep incline to park at work yesterday morning and there was a thunk and a rattle. The rattle was there when I started to go home, and went away shortly after, but now the car feels like it's pushing against something and transmission fluid is dripping out of the bellhousing. :censored:
It's been rain, snow, sleet, and high winds the last few days, so I didn't get a good look underneath last night.
Torque converter input shaft may have cracked and has taken out the front seal.
