Re: TSB 18-012-11 Rev.A 2011 builds
So I had a chance to test out the TSB 18-012-11a update as my wife and took a ride to the mall today with our two month old. Now that I had a chance to really test it out around corners, accelerating from a stop, driving up hills and in stop and go traffic, I can tell you that it drives much better than before. 1st and 2nd gears hold longer which makes the pick up so much better going into 3rd gear. No more short 2nd gear which was allowing it to shift into 3rd way too soon at low rpm which made it feel like you needed more pedal effort to pick up speed. Because of the improved performance, the Jeep feels lighter and much niftier....doesn't feel like a heavy vehicle. Before the TSB, the Jeep felt big and heavy due to the dead spot in torque....that's mostly gone. Much better driving experience. Driving in stop and go traffic has much improved as I mentioned that it doesn't shift into 3rd gear as much and as soon. Highly recommend the update if you haven't already.
