Mine is at 253K and no tranny issues except when the fluid gets a tiny bit low. They are very sensitive to low fluid, it seems. ( yeah, it's time to replace the pan gasket on mine).
The stalling can also be from low tranny fluid too.....but go thru Zeejay's list below and see if you can sort it out. (96-98 models have lots of PCM issues. I'm on my 6th OR 7th PCM, but at $300 each....it's cheaper than buying another Jeep with problems I dont yet know about)
Might want to take a look at this too.
Change the tranny filter and fluid, then click the link below for Zeejay's list. Go through it step by step.
