Trans filter - Change it or not?

[packmule1911]

I've read some day to never change the trans filter on an XJ. Can't figure out why not. Some also say that the fill tube is a big problem, and that you can't always get them out, etc.

I think I should change the fluid and filter since I got the Jeep last November, haven't done this maintenance yet, and have no idea when or if it was done before. Plan to change the transfer case fluid as well.

What do you folks say here about this topic?

I've got everything I need to go ahead and do the job, but I don't need an all-nighter because it's more than I bargained for.

Thanks.

If you never change the filter, you can end up with one like this in basic black

I hear you. Seriously though, some people say to never do it, as if it invites failures rather than prevents them.

I think that's a foolish position, but cars are weird. I had an old SAAB once; talk about weird.

I think I'll look into the dipstick tube first before I decide to take the plunge since it seems those can be a problem.

I did mine last year and with both a new filter and fluid it shifted a little better (had a slip). With the dipstick tube, its two pieces. One slips into the other and has an o-ring to seal it. Once you get the pan unbolted twist is back and forth while pulling, that's how i got mine off.

I can tell you that I put 75k on mine with never a single issue. Then I changed the filter and the front seal on the tranny started leaking around 2k later...

Take that with a grain of salt

I thought the filter was just a metal mesh screen? If so,a new one would'nt make a big difference unless it's really clogged up with something. But if it's like the one 4.3LXJ posted...yes they get dirty and clog up. Mines an 01, not sure what filter I have.

They act like a fuel pump tank filter that kinda sifts out debris before going into the lines. Remember piping on these things are vast and small at times so you will want the filter to be good to go.

Mine was just a metal case so I can't tell you what material was inside of it.

Planning to get back to this task soon. Looked at the filter kit, and the gasket is a simple rubber one. Because it's rubber, does it need RTV as well?

[4.3LXJ]

No, but make sure the pan bolt holes are not dimpled. If they are, it will leak

And don't oversight the pan bolts. Remember the case is aluminum. ;)

If the fluid looks ok, do a change, if it looks questionable do it but don't drain the convertor, the debris may be holding it together,... but a filter is always good:bacondance:
