I need some help from my fellow Tundra owners. I have a 2008 CM 4x4 5.7L with about 37K miles. I am experiencing a problem that I think is transmission related. When going up a fairly substantial incline going about 15-20 mph, when decelerating from 20 down to about 3 or 4 mph while on the incline and while still giving it some gas slightly so it is decelerating slowly, the truck suddenly jerks like somebody ran into the back of the truck. I have had it into the dealership, and so far they have replaced the driveshaft, without any luck in fixing it. Now I’ve been getting the runaround by the dealership and corporate case workers without any solution foreseeable in the near future. I would like to see if any of the other TS members have this problem, if they have gotten it resolved, or if some folks maybe are not even aware that they have this problem but after testing it you may find that you have this problem too. So to test it, accelerate up a hill so you are going about 15 mph, let off the gas pedal but not entirely, let the truck decelerate to about 3 mph while still giving it some gas. See if you experience the truck jerking sensation, if you have the problem you will know it immediately. It is easy to duplicate for the dealership, and they cannot deny it is a problem. Thanks, and please provide feedback here in this thread.
