Hello everybody. I have a 2003 suburban ls 1500. I recently started experiencing a shimmy from rear end while drivig between 40-50. It happens when I apply light pressure to gas pedal but once I reach 50+ or let off gas it goes away. I do have custom wheels & tires but had them rotated and balanced a week ago. Tires are in great condition, recent alignment and proper air pressure. If anyone can help, I'd be grateful.

depending on how bad the tcc shudder is;you could try a complete trans fluid exchange with gm dexron fluid. do not use aftermarket fluid.

A guy I work with drove the truck and immediately knew what it was. It helped that he had been a tranny mechanic prior for 15 yrs. Then google to back up his explanation.

Really? Whats considered a bad shutter to you (currently not a violent shutter)? What % chance would you give that this would work being that its been going on for close to a week?
