I noticed about two weeks ago that there was somekind of oil leakage coming from the rear of my 00' SS? I didn't think much of it figuring it was coming from the back differential and I had just recently changed the gear oil from there. But when I looked the differential was perfectly dry. I noticed the oil trail was traveling along that long middle beam on the underside of the car and the oil was dripping off at the back two bolts. I thought well maybe the oil pan or filter but they two are dry as well. Then I wondered could a back seal from the T-56 be leaking? I couldn't really tell but the front part of the T-56 is dry as well.

What are your thoughts given this? I appreciate your replies/suggestions. Thank You

 

took my z in for an oil filter change and the mech. told me the rear diff. was starting to leak just a tad. not sure if that's the case ,maybe have a mech look at it? leaks can be tricky to pin down i think.

 

yea a chevy tech guy said that my pinion seal needs to b changed...i have leakage in the back too...and i have a '00.

 

No the rear differential is fine the seal is absolutely dry all around. The leak is dripping off the back two bolts in front of the differential. The only thing I can think of is the rear seal of the T-56 is leaking or somewhere in the rear of the transmission???

I'm not gonna drive it and check it out closer this weekend.
