I can honestly say I JUST did this 2 days ago on my EA82 sedan.
For some reason, the holes in the cross member didnt match up and thus were a PITA to remove the back 6.
My advice (advice I was given from GD)
Jack up the front end. put it in some jackstands.
Take both engine mount bolts off.
Jack the transmission up (with the engine) as high as you can get it to go.
Start removing bolts. I think theres like 15 or something?
When you get the cork gasket from the dealer (if you do an OEM gasket, I recommend it) get some ultra gray RTV and make sure you coat the gasket in RTV... let it stand over night, or at least a few hours til its no longer tacky. (I suppose you could put a fan or heater on it and get it to dry quicker)
Then put it on, this way the gasket doesnt get all hard..
By the way... getting the old gasket off IS a pain in the neck...
I had to do a reseal because the jack slipped and crushed the oil pan, had to pound it out and I didnt use a gasket, just used RTV and 2 days later, no leaks, so I think my job went well, but the dealer gasket is sooo much better.
When you put it back in, get ALL the bolts started about half way before beginning to tighten them... the last few wont line up 100% so you have to slide the oil pan a tiny bit to get a bolt in, but it will all work out.
