This is a mini write up with more pictures than words.

Get all your tools and whatnot out so you dont have to run back and forth.
Image


Take off all the bolts untill you get down to the last one, socket is a 13mm
Image


Let that summabitch drain
Image


Hopefully you wont have SUCH a a ghetto way to catch your fluid
Image


Pull pan off after it drains, check pan for metal chunks..there was non in mine, just a little bit of dirt still cycling through from last time I did this. Eventually it will cycle out, THIS IS WHY YOU DO NOT DO MUD. No metal chunks, good stuff.
Image


Pull magnet off, clean pan with brakeclean or water, dry it, scrape off old gasket if there is one.
Image


Time to take filter off, it is under the pan that you pulled out, dont know exactly what size the torx bit is, it was one of the two in my 155 piece craftsman tool chest. But just have small torx near you.
Image


Check for wear and tear
Mine is fine
Image


Bolt new one back up
Image


Apply RTV or gasket rubber crap like I have
Image


Bolt her back up and put fluid into the tranny filler plug, on the V8 its to the back right of the engine block
Image


I put in 3 1/2 quarts, prob gunna add more.

Hope this helped some peeps.

You put gasket on the tranny pan?? The gasket i bought for mine said not to put any thing on there. Just to line it up and bolt it back in place. So i would check the instructions that come with the gasket that you buy and i have the v8 as well!!! And i thinki put 4qt of atf+4 back in mine!!!

naw... I'm good. I just remember when I finally cleaned all the mud off mine and vowed never to go "boggin" again I was covered it grease and mud from all of it splattering off from the pressure washer. Clean ZJ though. :mrgreen:

How old is that tranny fluid... Looks brand new. [smilie=bal_ask.gif]

Missed one step, once the cover is off you can either drill a hole where the magnet is and drop a nut in there then add a bolt with a fiber washer on there or get a drain bolt insert and put that in, that way next time you can drop the bolt to drain before you drop the pan. Much neater...

This is what they look like

The reason they don't put them in OEM on most is then owners would not drop the pan and change the tranny filter.

You don't have to put it on the bottom, the back would work too, that would only leave 1/2" or so of fluid in it.

2x on the drain plug idea, but when in need of a large drain pan, check out the rabbit cage supplies at Tractor Supply or similar store, I got a 3' x 3' poop tray that works great under trannies, radiators, etc. They sell bigger ones too.

I just checked the prices on the drain plug kit at AA, $1.99 in the rack where they stack the drain plugs. I'm actually considering putting them in my other jeeps differentials. Next month when I do all the diff fluids in the XJ and TJ's I'll see what the thickness of both the covers and the housings are.

Thankas for the info...However, if you want to do a "full" replacement of fluid, you have to have it pumped out of the tranny, t. converter and the lines. When you just drop the pan and refill it, you use about 4-5 quarts of fluid. If you have the system completly drained, which uses air, you will plan on using 15-17 quarts of fluid. It really sucks to drain a 1/4 of the fluid and change a filter just to add it to a system with 3/4 of the dirty, metal laced burnt fluid. But, great write-up nontheless.

I did this on my 98 ZJ.

Drop the pan, replace the filter, refill the pan with 4 quarts of fluid, then ...

Pull the transmission return line apart at the connection of the rubber line from the radiator cooler return to the hard line going back to the transmission. I believe I saw it near the wiring connection of the O2 sensor the other day when I was replacing the O2 sensor.

Put the end of the rubber hose into a clear plastic 1 gallon container marked at 1 quart intervals.

Start the Jeep, put the transmission in gear, count to 10-15 or whatever time you think will pump out a quart or two of fluid.

Check the level in the container, add the same amount of new ATF 4 to the transmission, repeat until you've used about 8 quarts of new fluid.

Warm up the transmission, check the level, fill as needed.

I basically did this procedure except I was adding a transmission cooler to the Jeep so I ran a temporary line out to where I could see the container from inside as I was putting the transmission in gear. I dumped out the fluid after a couple of quarts and repeated until the fluid was noticeably lighter in color. I used 12 quarts plus 1 additional for the extra in the transmission cooler.

Did mine a couple weeks ago and bought an O.E. gasket from Jeep that is reusable(to an extent) its a real nice gasket that seals well with no sealant applied, use them all the time at our shop. Also added a quart of Lucas trans fix to my trans fluid swap. This stuff works great and helps to soften up the seals in the trans to helps the trans shift better and leak less internal and external. Again we use the Lucas products at my shop a lot and have had real good luck with them. Just thought I'd add this for concderation. This is a really good post with very good pics, very nice!!
