Ok thats true, i should have most of the tools for it, and i know that i dont want a backflush done. It should be easy enough to do in a parking lot?

Hey guys, I'm not trying highjack the post. I got a same problem on my manual 1999 sahara. Should I try the same thing? Or there is difference between auto and manual trans.

Thanks

No, you will not need a jack. You will need a ” box end wrench like this one in the pic to remove the pan bolts that are in back covered by the skid plate. A torx bit, I think it’s a T25 maybe T30 to remove the filter. In addition, something to disconnect the cooler line at the transmission. Crescent wrench should work, that's all. Remember driver’s side. Crawl under there and look. Should be a metal hard line that goes into a rubber hose that then connects to the radiator. Disconnect the metal line from the rubber hose. Even if you have to cut the rubber hose to get it off, you can simply put on a new hose and use hose clamps to secure it. It will help if you first pump out the 3 quarts that are in the pan, so when you go to remove it fluid won’t go spilling out everywhere. Replace the filter by removing the three torx bolts holding the filter in place. Then reinstall the pan, add 3 quarts to the dipstick tube, then proceed in pumping out the rest of the ATF from the torque converter.

If you have a manual, then you do not have ATF or a filter to change.

The new ATF won't be coming out, only the old. If you put in more than 12 quarts to be sure you get all the old stuff out that's okay. So the answer to your question in no, do not put any that comes out back in.

Till it fills up your milk container to the 3 quart mark. You only want to do 3 quarts at a time, because that's all the pan holds.

You do not want to run the pump if no ATF is coming out. That will burn it up.

Here is my external filter I was telling you about. It holds about a quart, so at every oil change I replace this filter and add a fresh quart to the mix. It also aids in replacing the ATF in the torque converter, as you only need to remove the input line to pump the ATF into your empty milk container. No mess, very little spill and no more crawling around under the JEEP. Remember cool fresh ATF is the key to a long lived transmission.
