Liberty transmission question

[jzjohnz]

Hello members,

I'm a newbie both here on this forum and also as a Jeep owner.

Couple of months ago I bought a 2006 Liberty with roughly 20k miles on it. It has the 3.7L V6 with auto transmission and 4wd. I don't plan on doing any 4 wheeling with it, but I do like the way this vehicle handles and want to keep it maintained as well as I can. One thing I've all ready done is replace the motor oil with a synthetic brand and want to do the same for the transmission.

I would like to know how, if possible, I can drain the auto transmission AND torque convertor so that I can replace the fluid with a synthetic one. I don't want to just drain the pan and then have the existing torque converter fluid mix with the new synthetic afterwards, as that would defeat the purpose of replacing the fluid as far as I'm concerned.

Any helpful comments would be appreciated.

Also, I've read that this model has had its share of problems with owners, but it's such a joy to drive I just can't believe that a vehicle like this would be as worthless as some owners say. If any of you have any first hand experience with some of these issues, please post them as I would like to know if it may be in my best interest to unload this vehicle before it starts to really cause me grief.

Thanks for your help. :???:

It is possible to change all the fluid in the transmission yourself but it's pretty involved. First remove the pan and change the filter, then refill the transmission. Then remove the transmission fluid lines from the radiator. Place the line going to the transmission in fresh fluid, and the line from the transmission in a drain pan. Run the engine until the fluid runs clear.

Truthfully a lot of shops have equipment that can make the change for you, with a lot less trouble.

You Have a 42Rle Trans. the only recomended fluid for that is ATF+4.

I'm planning on using Amsoil ATF and from what I've read, it meets and exceeds the required ATF for this vehicle unless I'm missing something. Please explain if I am.

I have heard that shops that have a system that will do this do not like to contaminate them with non-standard ATF fluids such as the kind I want to use (Amsoil ATF). I haven't really checked it out but I suppose there may be some out there that would be willing to do it.

It looks like I'm going to have to do this myself since I've checked with a couple of local shops who told me they won't use customer's lubricant.

After changing out the pan fluid, disconnecting the radiator lines and following the rest of your instructions, I assume that the transmission pumps, or circulates, the fluid from the torque converter to the radiator for cooling then back to the pan & then up to the torque converter again. Is that about the path it takes? If not then the new fluid will get contaminated.

Also, you say to run engine until the fluid runs clear. I'm assuming that "clear" means free of any foam or bubbles, or should I be looking for something else. They're both red in color so foam or bubbles is the only difference I can think of to look for.

I have a 2006 Jeep Liberty. And yes it has had some of the issues that you may have read about in the reviews. first it was the abs/esp lights that stuck on. They replaced a part and then it took them another day and a half to find a couple of shorts in it. One was underneath and one was inside the dash somewhere. And now my left rear window does work right. I currently have it taped up so that it doesnt fall down into the door.
Inspite of all this I love it. It will go anywhere.
You might want to rethink the no 4wheeling. This is what is excells at.

When I bought mine (used) the same window was stuck in the up position and I had to take it in to get it fixed also. Haven't had problems with the others (yet) and am holding my breath, especially now that the air is getting colder.
