CJ7 TH400 Transmission Question

TH400 Auto 3 speed transmission
Quadratrac Transfer Case

After driving about 15 miles, transmission slipped but then reengaged almost immediately. Another mile down the road did so again and finally seemed to have lost all forward gears but had reverse. Flat bedded home. Next day started and drove short distance, progressed through all 3 gears but only short distance, didn't have time to warm transmission. Any thoughts why I would have lost forward gears only to have them return next day?

Might want to check the transmission fluid before you do a whole lot. I had a similar issue in one of mine years back and the fluid was almost gone. Had a leaking seal that I didn't notice as it was one of several Jeeps I had back then and where it was parked, I didn't see fluid on the ground as the leak was slow but after awhile it drained out enough...that was my issue anyway.
