Well I finally got the 4L80E into the car and on the road when I noticed my pinion happily leaking fluid onto the ground. I'm getting a 9" housing and axles in a few months so I just need her to hold on a bit longer. Zexel Posi and Richmond 3.73's with Royal Purple Syn in there now. Should I run a thicker 75/140 weight oil to slow the leak or just keep adding 75/90 as I go? It's not pouring out, but some is flinging onto the exhaust and tunnel.

AS long as you aren't developing puddles, add as required. Shouldn't need much either.

I'd just keep making sure the fluid level stays up until you get the new rear...anything other than that is just too much work for something you won't be using in the near future.
