Okay, if any of you all have seen my posts on other sites or even here, my rear main was leaking a couple of weeks ago. I had a shop replace it. GM parts of course, they put it back together, looked good! I was under the car tonight draining the radiator and my leak is back. Trans to engine connection point...engine oil. Anyone have anything for advise, or had this problem? Should I try another seal? The car only has 46K miles on it.

 

You had a shop replace your RMS? I bet that cost an arm and a leg. I think first, you should do as BIGKerneL44 said and check to make sure its not coming from somewhere else. I had my RMS and my intake leaking oil, and I fixed both at the same time, right before I swapped clutches, and it hasn't leaked a drop. Next step would be to take it to the shop that worked on it. Most places give you at least a 30 day warranty on their work, some places give a little longer.
