Well after a week of driving around with the new TCM program, it is much better than before. It isn't perfect, but it is getting better the more I drive it. I think the adaptive learning of the transmission is figuring out how I like to drive and adjusting the shifts accordingly.

Prior to the TCM reprogram, the transmission held gears longer than I liked, so I had to manually upshift a lot. It also wanted to stay in second gear past 4k rpm under normal acceleration and usually wouldn't shift into third gear unless I lifted off the gas pedal or manually upshifted. Highway driving was just as bad because it rarely wanted to stay in overdrive. I'd manually upshift to get it into 5th gear and it would downshift back into 4th gear almost immediately at 60+ mph. Engine wear and mpg suffered because I was usually running between 3-4k rpms a lot on the highway.

After the TCM reprogram, the transmission wants to shift into the highest gear as soon as possible. Sometimes I'm taking off from a dead stop and the transmission shifts from 1st to 2nd to 3rd and then downshifts back to 2nd because I had to give it more gas to get moving faster. It is getting better because I've learned that it usually happens when I'm light on the gas pedal. If I give it a little more gas when I start to accelerate, the transmission will hold second gear longer before it upshifts into third and then it stays in third gear without downshifting to second. It still feels like the jeep is struggling to get moving while the transmission figures out which gear it should be in. I'm hoping as the transmission learns my driving style that shifting from 1st to 2nd to 3rd will get better, so it doesn't feel as sluggish trying to figure out if it needs to be in second or third gear. I've never had to manually upshift or let off on the gas pedal to get the transmission to shift now, so it is much better from that perspective. My jeep also stays on overdrive on the highway for longer periods of time, so now my average rpms while doing 65+ mph is about 2500 or 2600 instead of 3k+. Overall the highway driving experience is a significant improvement.

I haven't tried wide open throttle yet, so I don't have any updates for that. I usually don't drive that way unless I need to pass someone quickly. The SC is more for moving my heavy jeep than racing.
