This was an intermitent problem on my 2001 Grand Cherokee, as stated before I had repllaced bot spped sensors in the tranny. About a 10 minute job for both, vehicle ran fine for about 4 months then started with the hunting for a gear , would bog right down when you floorred it and damn near quit!!!!!!. Put my computer on it again, and low and behold had a bad input speed sensor. Sooooo, I changed the crank sensor, which is part of the speed sensor system, brain, and it has been flawless every since. I am a very experienced mechanic, and replacing this took about 3 hours , as the old one was just about rusted in place, even thought its plastic!!!!!!!! Remove the starter completely before trying to get it out, took several doses of kroil to get it to move, eventooully got it out with a mini prybar and 10 in vise grips. This should save someone a lot of trouble. Eliminated the up/down shift, harsh downshifts, the xtra little kick in the *** on the upshift, bucking stalling and bogging out when trying to pass. Thank god, I finally got it fixed. !!!!!!!!!!!!!!!!!! Time for a beer now.!!!!!!!!! Mikey from EmseaMotorsports
