Probably a stupid question, but I need to know...

99' Sport 4.0 .... Gonna drain and fill, drive, drain and fill, drive, then pull the pan replace filter, drain and fill and drive......

Seems like the prefered method overall for diy....

Jakeshain

is it a manual or auto?

The Automatic does, but getting the pan down is another story.

My 98 has a drain plug but it wouldn't come out, was afraid to snap it off, so I dropped the whole pan and changed the filter too. To drop the pan needed to unbolt the dipstick and trans crossmember to pull the pan down

Get down on your hands and knees and take a look, it's that simple.

Auto..

Hey, thanks for the insight... I would have never in a Million years thought to do that! When my son gets home with it this weekend I will do just that...In the meantime I am trying to prep for the work that needs to be done...So for now, I'll just ask the quality people of this forum to lend a helping hand with a few simple questions...

Carry on...

Without having the jeep here to take a look, is it an Asspain to drop the pan on these things?

I loved the dialect. But dropping the pan is not hard just do it with cumin sense or get wet. By that I mean after you drain the fluid with the plug then loosen toward one corner to be safe.

My '99 with the automatic trans has a drain plug. I've done the drain, refill, drive drain, refill sequence several times now and it's working fine.

When it warms up again, I'll probably pull the pan and change the filter. I've scoped it out and notice a heck of a lot of pan bolts and I've heard that the dipstick tube can be a pain to deal with.

cool, thanks for the responses... I'll be doing the drain, fill drive, drain, fill drive, drain, drop, fill, drive thing this week...hopefully...

Use Dex/Merc III compatible fluid................

Or you could save yourself the hassle of doing all that and just do a fluid exchange by disconnecting the transmission line going to the cooler and having it run into a bucket or something with the vehicle on. You'll want another person adding fresh fluid as it drains the old fluid out. Continue until fluid coming out of the line is red. Don't run it dry.

Granted I'm a bit new and at times dense. What is the purpose of drain, refill, drive, drain, refill,drive? To make sure all the old fluid is out?

Yeah basically helps clean it out. Stirs and picks up debris on the first fill.


These can be a pain in the butt to get back together.
