My Rear Main is leaking

[ThisGuyUKnow]

Can I replace it without dropping the tranny? A new seal is like 20 bucks but to get a shop to do it looking at 400 bucks in labor so looks to me like If i am going to be replacing it I am going to be the one to do it and I have never replaced one before.

Anything else I should do while I am in there?

Remove the oil pan. Remove the rear main bearing. You have a 2 piece seal. The piece in the main bearing you removed is easy to replace. The top half is tight on top of the crank shaft. To make it easier to remove loosen up the other bearing caps. No need to completely remove the caps. Then you can press one side of the seal out. Once you have enough out that you can grab it with a pair of pliers you should be able to pull it out. Then push the new seal back in by putting it under the crankshaft and pushing it in.
