yep, got to get all of that old fluid out, mixing dex/merc, and mercV in my fathers ranger made it start slipping in and out of gear and shifting really funny. we had no choice really... we were stuck in the middle of nowhere towing a car back, when she started dumping fluid from the pump seal. all we could get was gas station dex/merc...
its quite simple since we do have a drainable TC, which is super nice. the only problem is getting all the fluid out of the valve body. but that's a tiny bit of fluid and you probably wont have an issues with it mixing.
theirs always flushing machines as well. some shops don't charge too much, and if its a decent machine, they work quite well. BG's machines use a box with a diaphragm inside that is filled with fresh fluid, and the trans will pump out old fluid on the other side of the diaphragm, using the pressure of the oil pump in the trans to push the fresh fluid out of the box, and into the trans. they work well.
otherwise its been said that the machines with their own pumps will sometimes stir up sediment from inside the trans and kill it. not sure if its true, but its something to consider. especially on a high millage trans that might have a weaker pump inside. i guess the weaker they are the more metal filings and things they let settle around the inside of the trans. and when you put a pump on their forcing fluid in at a much faster rate, it can stir all that stuff back up and circulate it through your valve-body. especially if the magnet in the pan is piled with filings.
otherwise that being said, the 95 trans is indeed a big pile of garbage, but unless its slipping real bad or has valve body noise or something, i would run it till it dies before going through the hassle of swapping in a new one. but when it dose die, anything 98 and up is an excellent swap(mechanical diode clutches, better valve body). 97's are still quite good as well and they don't require a repin if that intimidates you. but its a crap-shoot whether or not you will get the mechanical diodes or not, which you DO want. i know mine has them, but I'm pretty sure mine was actually a late 97 early 98 MK8 trans.
