zj trans slipped, then restart and go another 1/4 mi

Hey everyone! New here, but I did check the forums for this problem...The day before my trans slipped, I used my zj to move my broke 69 ford and a saturn across my yard. I had to jerk on the truck to get it to slide on its stuck wheels, using 4lo. Didn't get hot, and drove fine the rest of the day. When I drove home from work the next day, it took off ok, but seemed funny on the shift into 2nd or drive, and just revved like it was in neutral, after 1/8 mile. (I saw thread like this here- but it was never resolved) I stopped for a count of 10 seconds, restarted it and drove another 1/8 mi, and it did the same thing. I stopped, did a 10 sec count, started it back up and it went a lil ways. I started turning it off and coasting for 10 secs in neutral, and restarting. Did this for 2 miles, till i got to a big hill, then got a buddy to tow me home. After sitting 3hrs before the tow home, it acted no different. When i go into reverse, I hear what sounds like a p.s. pump low fluid growl (its NOT the PS pump)I didn't stop long enough to "cool" anything. It seems to me that fluid is not circulating enough-a restriction either at the filter, or a check valve I read about by the cooler, maybe? I had an escort as a kid that flaked off oil crud into the pan. Same deal. When the oil light came on, I shut it down long enough for stuff to fall off the pickup, then drove a ways. The xj trans fluid (atf+4) looks and smells fine. Any ideas? I'm severely strapped for cash at this time, but as a jeep and sooby owner, I am very mechanically inclined, and willing to try anything. gonna check trouble codes now..thanks for any input!

did you happen to do much jerking by going from neutral to drive with your foot on the gas? or going from drive to reverse to drive without letting the wheels completely stop spinning?

Nahh, I stopped doing that when I was a kid and broke stuff all the time. The only jerking that was done was from the slack in the chain, which was intentional. Think it's a fluid pumping problem, due to the growling it made when in reverse, but right now I'm dropping a motor back into my outback, and just giving the ZJ dirty looks outta the corner of my eyes. I have a 1990 xj with no title, but it runs. Are the automatic transmissions the same? Oh, forgot to mention- the ZJ has 254,000 mi on it, and it's all original. When I got it last August, it always seemed kinda sluggish on the throttle, like something was holding it back, and it just took more gas to get it to do anything. I thought it was a sticky brake caliper (my jeeps always came down with that prob) but in neutral, it coasted fine. I downsized the tires a size, back to stock (narrower and a lil shorter) and seemed to roll and drive much better.

grinding isn't good and indicates hard part damage. i'd suspect you'll find metal in your pan when you drop it to investigate

the xj and zj do not share transmissions. the aw4 xj trans can be swapped in, but it's a fair bit of work to make it right.
