Rich, If you have dropped a tranny before then it can be done in 3 to 4 hours. Then it has to go back and hope nothing happens while doing it. You make want to have a set of engine mounts on hand if they break. I noticed you saying oil/coolant. Hope there isn't any coolant coming out of the rear main seal. If there was or is you have more problems. It's also a good time to look at the clutch while you have it down.

I had decided on a total engine rebuild, but I have been advised that it's just un-necessary by the good folks in Houston. After crawling under my car, I've pretty much confirmed that the crank seal is the source of a large oil/coolant leak (I know, you're saying that if that was the problem, there wouldn't be coolant in it). I believe I have a combination of problems. Warren has advised me to just drop the tranny in my driveway and replace the seal.
