2006 GMC Sierra 1500 transmission complaints
Page 2 of 2: complaints 11 to 13 of 13, newest first, as owners wrote them.
When the transmission shifts from 2nd to 3rd there is a hard clunking, also when it down shifts from 3rd to 2nd. I have had this 2006 gmc for only 10 months and I purchased it new. I took it to my local dealer for the problem and they told me that this is normal noise for a four wheel drive. I have had many 4x4 gms in the past and not one of them has had this kind of a shifting problem. I have purchased three new gm's in the last 4 years and I have had problems with all of them, I think I'm going to trade it in for a toyota.
Seats popping noise when weight shifts (start,stop,etc.)first attempt was to replace the seat back. Second was to replace the entire seat minus the cover. Third time in the service manager wanted to contact the area gm manager for direction. The gm area manager told the service manager to make no repair and direct me to call gm. This truck also has been in for service to the brake rotors to be re surfaced with only 4,600 miles on the truck. The transmission has re calibrated two times one for the lock-up torque converter,and once for a hard shift from first to second gear. The truck has a harder shift now than before.
