2002 Infiniti I35. Transmission started downshifting easily without much pressure to the gas pedal *highway. Problem seemed to go away. Yesterday, wife was driving car and lost power ie, transmission seemed to disengage. Rested car 20min, drove slowly home. Checked fluid. Full not low. Car rested 45 minutes and it drove fine after that. Electronic shift sensor?

Okay, I baught an 01' tiburon last march. When I first had trouble with the tranny it wouldnt shift into fourth and no it wasnt the overdrive button. Then it started downshiftling like what your experiencing then I lost reverse. Ammco rebuilt the tranny. I would take it to them, they will inspect it for free. You may just need a tran fluid flush. You should know that in the automatics the tranny is the weakest part of the car. The engines are great, just everything around them seems to fall apart after 120,000 miles.
Ammco offers a free inspection service. However Just from experience - if you need a new auto tranny it is cheaper to buy one already rebuilt (with warrantee) and pay to have it installed than to rebuild the one you have.
Cheers to hyundai challenge : )

well the low cost way to go first would be to try and change the trans fluids. If the problems still remains the it may be an internal problem

The procedure goes like this. First get in the car and lock all the doors. Secondly insert and remove the key repeatedly until the turn signal indicators on the dash flash twice simultaneously, it should be like seven or eight times. Then turn the key on and press the lock button on the remote and the lights should flash again. After that turn the key off and manually unlock and open the drivers door, then shut it. Wait a few seconds then try the remote.
