Update from OP here. 05' LJ has 47K and yesterday I changed the rear diff oil, the front diff oil and the NSG370 oil well as greasing all seven fittings of the front end (including the two for the upper ball joints that you have to unload the suspension to get to). Status = All old gear oil was VERY dirty and the drain plug of the tranny was maxed out on fine metal shavings (it looked just like the pics I've seen other members show in here). I bought the 3-pack of 12, 14, 17mm hex sockets from Autozone for $10.99 and they worked very well, just used lots of solid pressure with a long breakover bar (push up onto the bolt firmly as you attempt to loosen it). Also as many others stated, it appears the factory did not put in enough tranny gear oil one quart came out.

I used Penzoil Synchromesh and it definitely shifts smoother, albeit that may be more due to now having a full case. The PS was at Advanced for $7.50/qt and it is the equivalent of many other synchromesh fluids as quote-noted in my previous post. To the last poster, I'm not sure of the torque on those bolts but I used pipe thread on the drain bolt and didn't tighten it more than ~25 lbs or so leaks. For the fill bolt, it's just a fill bolt long as it's "snug" it will be fine.

Thanks to all for your advice and help.

You still got 4qts in the torque converter. There is no easy way to "drain" all the fluid in an automatic tranny. It can be flushed pretty easy if you get some hoses & plug em in and use the tranny pump to do the flushing.
