Default Re: Lurching 40 to 50 mph slight hill

Now at 12000 miles and vehicle still jerks at slight throttle once the torque converter locks. It is in the shop now to be investigated. The loaner has the same problem, if not worse, with only 1200 miles on it.

I am surprised that no one else has this problem since it appears to be a generic design defect according to what I've been told and experienced.

Perhaps driving on flat or slightly inclined roads at 40-45 mph is not common?

Oh, and to those who doubt, even my wife who is not a car nut notices the problem now. Also, I have driven probably 100 rental cars and owned about 20, none of which have had this anomaly. My guess it is related to the full time 4wd and how the slip shafts are arranged with the transfer case which is free to rock back and forth. Does anyone know of a shock absorber for the transfer case?
