ATF+4 or Dexron/Mercon?
Hi Guys & Girls,
I'm sure this has been covered, but I just want some up to date answers.
I just recently found out that the previous owner of my xj was using ATF+4 in the tranny. From what I hear this should not be used and Dexron/Mercon should be. Is this the case? Also, if this is the case, how do I going about changing the tranny fluid in order to make sure all the right stuff is in there and the ATF+4 is out?
My XJ has 63,000 on it and from what I can tell ATF+4 was put in it at 30,000 miles.
Would really like some feedback as quick as possible, because if ATF+4 shouldn't be used, I want to get it out of there.
Thanks!

That's a Different tranny. My .02 TF, drain what will, and refill with the correct Dexron III fluid. Then repeat with engine oil changes. You will only get a few each time, but after two or three you will be about flyen right.

Then dex3. The xj's did have an optional Chrysler tranny but not the aw4.
Not a big deal. I like the triple flush method used buy acura. Drain the old ATF out, fill with dex3. Do this three times. Driving it apr 5 to 8 minutes between changes.

5-8 minutes...because this has been evaluated in a randomised placebo controlled double blind multi centre study?
Just do the drain and refill procedure and drive in between and keep doing this until the ATF stays red.
Or don't even go through the hassle of repeated procedures and do what I did and do a so-called forward flush and be done with the entire fluid exchange in 15 minutes at home. Wrote up the procedure somewhere in one of the threads, can't recall where anymore.
AW4 uses Dex III/ Merc. Anything else is at your own risk.

if you're trying to remove all of the fluid I'd use the unhooking trans lines method and fill with dex merc along the way.

Thanks guys. What is this drain and refill procedure you guys are talking about? I keep reading that the ATF+4 is not good, so I want to get it out of there and get some Dex/Merc III in there, but I heard that mixing the two isn't good either. I also am worried about doing a full blown flush as I've heard that creates other problems sometimes.
That's all there is to that.
I wouldn't do a what you called " full blown flush" either, and is not necessary . Especially those flushes they do in shops....leave those.
The forward flush is not dangerous or damaging to your trans at all, since you use the transmissions own 'pump' to get rid of the old ATF, while you poor in the fresh ATF at the same time. Nil hight pressure maachines or the likes involved. Once it comes out clean, you're done. Good thing about this: it's fast, safe and you change as much ATF as possible this way (say nearly all) in one single procedure. As long as you make sure you poor it in the same time it comes out; that way your pump will never fall dry.

Drain and refill: draining the ATF via the drainplug and refill with the same amount that you drained out (assuming correct level has been checked). Drive around for a few days or so and repeat this procedure. Keep doing this until the ATF that you drain stays a red/dark pink colour. Some will drop the pan on the last drain to replace the filter, but this is not mandatory. This method is fine and perfectly safe, but you will need the procedure done a few times, since you only drain part of the old ATF at a time.
That's all there is to that.

Also, I assume this mean's I'll have to purchase about the 3 times the amount of Dex/Merc III that I normally would since I have to repeat this process?
