I have a 258 with TF 999. The rear main seal appears to be leaking a little oil and I would like to have it fixed. At the same time, and of a more serious nature, the transmission pan gasket (I think) is leaking tranny fluid onto the exhaust pipe.
I have already purchased the RMS gasket and a new tranny pan and gasket.
Roughly how long should a shop take to correct these issues?
I was guessing about 6 because they have to pull the exhaust and drop the skid plate/transmission and the RMS is about 2 hours all by itself yes?
Actual hours, I'd expect it to take a couple days. You really have to seal up that oil pan gasket and let it sit overnight at the very least before running it. Probably the same goes for the transmission seal.
I can't speak for the transmission work, but I'd guess you were about right on the RMS. Figure 1-1.5hrs to take down, then another 1-1.5hrs to sew it back up. Bank on 2-3hrs labor.
I'd also expect to be charged at least a couple hours labor for pulling and replacing the skid plate + the transmission job.
It is also worth running the engine a bit, then take a clean rag and wipe the back of the head below the valve cover. Valve cover leaks do a great imitation of a rear man seal leak.

Is there any reason I shouldn't suggest doing this yourself? As a novice, replacing the RMS was the first thing I ever did with my CJ. It took me a weekend, I was thoroughly covered in oil afterwards, but it cost me all of maybe $300, and that's including a full set of Craftsman tools (i.e. the professional set), the oil pan gasket, RMS, black RTV, and beer. And I don't drink beer.
