Just wanted to say thanks!
I can't remember who it was that posted a TSB for the third to fourth gear torque converter lock up changes, but it made a world of difference for me.
One of my biggest complaints with my '08 liberty was when it felt like the acceleration would just die off when causually driving up a slight incline or load. Used to drive me crazy, but the TSB flat fixed it. Now I'm a happy camper once again. I took it in to Ed Voyles with less than 800 miles on my warranty (my Jeep doesn't see the dealer much) and expected a little resistance, but they were more than happy to do it, no questions asked.
Thanks again to who ever posted that TSB, it sure lets me enjoy my liberty that much more.
