96 xj aw4. I'm wanting to do the basic fluid change without dropping the pan but I've read if you mix the dex/merc and atf+4 it could be bad and I don't know what the PO used. I believe he used wally world (tires are from there) for service and from searching seems a lot of places will tell you to use the atf+4 (thanks CF for the right info 
). I don't seem to have any slipping issues, although I did experience the slips in drive but not if I start in 1/2 (which from searching seems to be a tps issue that makes it go into limp mode). Any way to tell which atf is in there or do I just hope he used the dex/merc and proceed with the basic fluid change? Thx in advance.

ATF+4 in an AW4 isn't guaranteed to cause problems in every unit. In most high mileage units it causes slipping... but not all. Mixing them won't cause any issues - they're not corrosive or chemically reactive or anything. Buy the right juice and do your thing!

Cool. Someone in one of the threads I searched mentioned that they could jell up or something but I don't know his credentials so I'll take your advice as I've seen you all over this forum
. And I just read a similar thread yesterday on the linkage adjustment but I like the diagram on that one better. Thanks again.

Calling any and all a/c techs
I have a question, maybe two. I just got done installing ALL new a/c components. It is a completely bone dry system. The old compressor called for 8oz. of oil so that is what I put in the new compressor. While adding it, I rotated the clutch to circulate the oil. I put the oil in on the low side of the compressor and when I got close to having the 8oz. bottle of oil completely emptied, it started coming out the other port of the compressor. I was like, well it is full.
I was told that the oil will circulate through the system after it is re-charged and up and running so there was no need to put oil in the evaporator, condenser, and accumulator.
Before I pull a vacuum on the system and re-charge it, my questions are 1) Is it bad that oil started coming out the other port on the compressor when rotating the clutch? and 2) Should I have split the oil up through the entire system ie. 3oz. in accululator, 1oz. in the evpaporator, .75oz in the accumulator and the rest 3.25oz. in the compressor?
I would like to make sure I am good to go on the vacuum and re-charge or if I need to pull the compressor back off and drain some of the oil out of it and redistribute it in the other parts.

This may be different depending on the years, mine was a replacment for a 88'. But I believe the concept is the same.
Maybe I did it wrong. Dunno. But my a/c blows ice cold with no issues.

When I replaced my compressor I added oil in the bottom bolt of the compressor. I had to drain out all of the mineral oil by rotating the clutch, once empty I added it in the same hole on the bottom of the compressor.

I saw that bolt you are talking about and it did not even dawn on me to take that off and drain it that way. I think there was still just a tad of the shipping oil left in it. Not sure if that will hurt anything mixing with the PAG oil. I got as much of it out as you can.

I'm trying to remove and replace the oil pan on my 2000. The oil pan support bracket or rear main seal bracket or girdle or whatever it's called is getting in my way. I've tried hammering a socket onto the bolts there, but it's like the bolts are jammed against the bracket itself. I can't even get a flat screwdriver between the bolt and the part it sits against. I'm determined to get this thing off, but I'm at a loss right now.
It seems like this bracket is metal. Has anyone else had issues with this thing? I don't mind breaking it if I have to, but I don't want to break anything that's going to be difficult or expensive to replace.
Any suggestions?

So I set my backlash to .011.
Now this is what my pattern looks like...
From what iv read, these patterns with my backlash set correctly shows the pinion shims need to be reduced.
Only problem is there's only one stock pinion shim in there....
