Last week I changed the cps on my 2002 with a 3.5, It had the typical tach and starting problems. It was very easy, you just have to get the starter out. after the repair everything was great without a relearn. It idled smoother, the tach went back to normal, I even gained 1.5 mpg better gas mileage. the best part was the shifting was not as harsh as it was, it was very surprising. If I knew it was going to do that I would have changed it years ago. But today a little more than a week later it is starting to shift hard again. Has anybody else experienced this? Does it have something to do with the computer relearning something. Please let me know.
Its common issue with 3.5 trans you need to scan with tech 2 or trans scanner and if you get MAX adapt code its deff trans need to be rebuild.
