aemsee Posted February 13, 2007 Share Posted February 13, 2007 If it is an auto and an AW4 ( which it SHOULD be) there is a 14mm drain plug near the back of the pan. Just take it out and let it drain for as long as possible to get as much fluid out as you can. Overnight is best. Watch for the copper sealing washer that goes on the plug. Sometimes it sticks to the pan and falls off later. Be sure to use ONLY Dexron in the AW4, NOT the Chrysler 7176 fluid. Link to comment Share on other sites More sharing options...
whatis42 Posted February 13, 2007 Share Posted February 13, 2007 I'm planing on doing this tomorrow if its not raining. What about the filter does that need to be replaced? Link to comment Share on other sites More sharing options...
Twisty Posted February 13, 2007 Share Posted February 13, 2007 its a good idea to, but its prob ok if its not. its just a very fine screen that filters out particles. if you drop the pan get a new gasket (some come with filters) and clean off the magnets at the bottom of the pan, and REMEMBER to put them back.

carnuck Posted February 13, 2007 Share Posted February 13, 2007 Make sure you count how many bolts hold your pan on before going to the autoparts store. There is 2 different ones available. Link to comment Share on other sites More sharing options...
GirsMJ86 Posted February 13, 2007 Share Posted February 13, 2007 i always have mine sucked out through the filler pipe. gets all the fluid out along with all the sludge and crap. makes it shift a lot easier and just better overall. i don't think i will ever drain it the old way again. i also use all synthetic fluids in mine so that helps too. if its never been done i would get it done at least once with how old these trucks are.

Eagle Posted February 13, 2007 Share Posted February 13, 2007 Sucking the fluid out through the filler still only gets about half of it out, because it doesn't drain the torque converter. Doing it that way is no better than just using the drain plug. The filter is not easily changed like an oil filter on the engine. To replace the tranny filter screen you have to drop the pan. The lower part of the filler tube is welded to the pan, so that has to come too. The upper part of the fill tube is pressed on with an o-ring between the two halves. Usually, in an older vehicle that o-ring is so hard that you need dynamite to get the two halves of the tube apart, and you'll most likely trash the upper end. A good Jeep dealer keeps them in stock, because they don't bother trying to save the old one, they assume it's trash and replace it with the filter. I did one that had 165,000 miles on it. It was an '88 XJ and I worked on it in 2003. The old filter would have been fine. I'd suggest not worrying about it unless you're having a problem. As to synthetic tranny juice ... girsmj86 is the first and ONLY person I have ever heard of who has used synthetic in an AW-4 and not experienced problems. I think you're better off saving your money and using conventional tranny fluid. Link to comment Share on other sites More sharing options...

I don't think the fluid is all out. Almost half the total volume of fluid is in the torque converter. I know I'm a stick shift guy and autmatics aren't really "my thing," but my understanding is that the only way to get that out is to drop the tranny and pull off the torque converter. Otherwise, even dropping the tranny pan only dumps what's in the pan, not what's in the converter. Link to comment Share on other sites More sharing options...
