96 cherokee o2 sensor messing with trans?

96 xj 4.0 4x4. auto trans. recently it would rev up while driving then kick back into gear. only did it once or twice in like say a 60 mile drive. the check engine light came on threw a o2 sensor code after the converter.. well tonight while driving down the highway it kicked out of overdrive into like 3 gear, came to a stop had no power like it was stuck in 3rd. pulled over turned it off and back on and had full power. would a bad o2 cause this?

On my 96 the forward O2 sensor went bad. It caused the engine to buck and lose power intermitently. The trans would down shift due to the engine running bad and losing vacumm. Check the codes. If it is an O2 sensor, I suggest replacing both. At least mine had 2, one on down pipe and one after the cat.

It's the crank sensor!

You always should chase every code that occurs, but that symptom does NOT sound like an oxygen sensor issue to me.

You would need to determine if this is an electrical or a mechanical transmission problem if this continues. Consult the factory service manual for how to do this.
