Occassionally we have had to put in a torque converter due to shudder on lockup. Are you sure your problems aren't related to the MDS kicking on and off?
Hi RamTech, I had the drone issue with my 2011 Ram 1500, had the Torque converter replaced for the annoying drone with a R8051146AB (Re-man converter). Then the shudder started to apeared when the torque converter locked up, brought it in. So the dealer replaced the torque converter with a RL051146AB (new) torque converter. But when I am going on an exit on the highway ( coming from 100 kms/hr) to coast down to the exit speed limit 70kms/hr, then to maintain the exit speed (70 kms/hr) by lightly applying throttle on a down hill grade exit, the shudder appears. What the heck is going on? They replaced the torque converter with supposedly a new one, doesn't shudder as severe, or as often as the re-man converter did. But why is it still a shudder there, like running over rumble strips? Just wondering if you came across with an issue like mine. My dealer refuses to change the converter again, and it did not act up when they were recently diagnoising the truck for the shudder again. It is aggrevating, so as soon as I came home off the exit ramp of the highway (110 km/hr) to coast down (slight down hill to 70 kms/hr), and maintain speed (70kms/hr) with light tap from the throttle, the shudder would happen.
