I tried posting in the drivetrain forum, and got no responses. maybe i'll have better luck here.
1989 YJ with 4.2L and 3 Speed
My jeep won't shift out of second. i did a filter change and it shifts perfectly into second but won't go out of it. and it seems to take a little while to engage in reverse.
if it's ruined would a transmission from a newer jeep with a 4.0 liter bolt up to the motor and transfer case??

As far as I know, only an automatic from a YJ (of any year) will be a direct swap. The YJ uses a TF999 which is a 3 speed with no lockup convertor. The AW4 (found in similar year XJs, ZJs & MJs) would need some input for the lockup convertor feature.
yeah. i was hoping to keep it simple. but of course that can't be done. haha. i wish knew y it just stopped shifting. it went from perfect to not even trying for third
I run a TF999 in my YJ. To me it sounds like you have done the basics on trouble shooting. How many miles on tranny? Was the fluid bad when changed? Was there a ton of metal in the bottom of the pan when you took it out.? The magnet in covered in metal? If you had any or all of these I would say the tranny has seen better days and it is in need of a rebuild.....
115,000 miles. the fluid was as expected. probably a little burnt. magnet was covered in goop, yes. no large metal shards. it just seems weird that it would go from perfect to needing rebuilt just like that. it didn't slip or anything. then it just stopped shifting into third.

Sounds like there is not enough fluid in it. Not familiar with the jeep automatics, but have dealt much with the turbo 350 auto. When they are low on fluid, they won't shift properly. Also, after you fill them to level, need to run and shift them to pump the fluid around, then check the level again. Don't want to overfill though. Did you pull the pan for the filter change? did you put a new gasket on the filter?
the old filter was pitch black. even if i held it up to my work light i couldn't see anything trhough it. i figured that it would start working after i put a new filter and fluid in it. but i was wrong. i have put about 150 miles on it. and it still won't shift. the fluid level is right. it's just not shifting...
how come all the other sites i have seen say that it has a 904 or 909 transmission in it?
i was thinking about trying to rebuild it myself. where would i get a rebuild kit from it?

as far as i know it is all origonal.
and yeah from what i read automatics are pretty simple. but they just seem scarry to me. this will be the first one i attempt on. i guess i'll see how it goes lol
i was planning on doing some research tonight. seeing if it seems do able. i just wanted to know which trans i have. cuz ppl on here say i have tf999 but everywhere else i see sais 904 909
Automatic transmissions
TF904 - TorqueFlight Automatic behind the I4 '94-'95, prior to this, the YJ was not offered in an automatic with the I4
TF999 - TorqueFlight Automatic behind the I6
According to our information your transmission is also referred to as a A904 if that's the case we recommend our super kit (less steels) part number TRS12007CF
fits 72-98 $109.00 plus
I gave the website a look. and i don't think they sell those kits anymore. i found the automatic rebuild kits and they don't sell one for jeeps? at least it seems that way to me.
hmmm well i'll deffinately give that a shot. because the transmission worked perfect then. i took it off roadin. when i got back on the pavement. only 1st and 2nd worked. so if thats all it is. then i'll be all set because the transmission WAS in good shape.
