jeep 4.0 stuck in limp mode, AGAIN

ok, so to add to my overheating issue, really not that big of an issue, my tranny just decided to start bein retarded. Sun afternoon i put in a new transfer case, bolted right up, plugged it in, did a little rock crawling. Tues i decided to change out the tranny fluid and filter only cuz it hasnt been done in about, 70,000 miles or so. (yeah i know) so dropped the pan, drained it into a bucket, well some of it, changed the filter and put it back together. Forgot the ATF at the store so picked sum up from a convenience store down the street, BIG MISTAKE. Put the ATF in, warmed it up, ran it around the block, added a bit more and went rock crawling again to check things out. All seemed ok. Wed everything is fine. thursday morning wake up, start it up, leave the house and only get first gear, nothing else no matter wut i do. switched the ignition off and on while driving a few times to see if it helped. After 10 times or so, it stopped doing what it was doing and drove fine rest of the day. Did it again this morning, (friday) so look at my atf and says "not suitable for cars made after 1963." WTF!!??Who the hell stocks this stuff!?!? so go to the store, buy the good stuff, drop the pan change it again, no help. Stuck in 1st gear entire day, do sum reading see that people have problems with governor pressure sensor and solenoid. replaced them both and now, only have 2nd and 3rd and thas manually shifting. And even first if shifting from neutral to 1st. Took it to have codes checked, no codes came up, so nothing to clear off the computer, tried disconnecting battery for an hour or so and still nothin. O/D light stays on and stuck in LIMP mode. So after my long story and even longer week, this is how it ends up. Any ideas out there what to do next???? Cuz im stuck anf frustrated as hell!!

Transfer Case
Mounted behind and driven by the vehicle transmission, the transfer case transmits power to the front and rear driveshafts in 4WD Jeep vehicles and offers high and low range.
