Grand Cherokee vibration fix

by Bill Cawthon on

For those that have purchased a new 2011 Jeep Grand Cherokee: A problem has surfaced – it’s a vibration at speeds between 45 and 55. The problem is a shift control module in the transmission that hangs up and doesn’t let the transmission shift into the next higher gear; consequently the vibration starts. When you accelerate, the vibration goes away but at 45/55 it holds steady. If this happens to you, go to the dealer: they are aware of the problem and it’s about a 40-minute fix.

Thanks to Bill Wetherholt for the tip!

Bill Cawthon grew up in the auto industry in the 1950s. His Dad worked for Chrysler and Bill spent a number of Saturdays down on the plant floor at Dodge Main in Hamtramck. Bill is also the U.S. market correspondent for just-auto.com, a British auto industry publication, and a member of the Texas Auto Writers Association, which has named the Jeep Grand Cherokee the “SUV of Texas” several times and named the Ram 1500 as the “Truck of Texas” two years running.

Bill has owned five Plymouths (including the only 1962 “Texan”), one Dodge and one Chrysler and is still trying to figure out how to justify a Wrangler. He also has owned at least one of every 1:87 scale model of a Chrysler product. You can reach him directly at (206) 888-7324 or by using the form.
