It uses r-134a Freon and the capacity will depend on if you have rear a/c. There should be a label under the hood that shows a/c capacity that will give you an exact amount but should be around 2 lbs. for just front air and about 2.8 lbs. for front and rear.

hi i had the same it was my four drive case

It may not be all your transmission it may be your rear end going out with that many miles alot of stuff on it will be needing a checkup.

on the end of the dash board thats a cover it pops off i think both sides

could be throw out bearing any vibration?

I was told by a tranny mechanic that it was a problem with the transfer case, some kind of chain is sliping, I think this sounds weird, but our explorer is only slipping between 2nd and 3rd, anyone out there thinks we are getting duped, as we are thinking?

Probably Needs a replacement clutch. You could check the slave lever adjustment is ok but thats probably wishfull thinking.
Get to know a good mechanic
