I found a post from "GCLimited", He describes how he did a Battery disconnect, and how that improved his 8-Speed trans operation, the thread has responses from others who also tried it with positive results....So, still being very skeptical, I figured what the heck, it's easier than taking my Jeep back in for service at the Dealer...So I disconnected the batteries neg. terminal, at the battery itself, let the car sit for 30 minutes and reconnected the battery. I was not really expecting much, but wow, was I surprised. The first drive after doing this was entirely different. The car remained in 7th gear when going about 40 mph until I almost came to a stop...Before it would keep downshifting, as soon as my foot lifted from the gas pedal, and the car felt like the brakes were being applied between every downshift.... Now it feels more like all the other automatic transmission cars I have owned and driven....The thread seems to indicate, that this fix has been lasting for the people that have done it so far......We will see, but it has corrected my one biggest bitch about my new SRT....as a long time mechanic on cars, airplanes, boats and motorcycles, if someone had told me this in the past, I probably would have thought they were nuts, but really it has worked for my GC SRT, and I recommend anyone having 8-speed trans problems give this a try, it's simple, quick and painless...hardest part getting the battery clamp to come off, suggest a small screwdriver to gently spread the battery clamp just a little, so it will easily lift off.....anyway my thanks to GCLimited for his post, hope this works as well for others
