My '05 CRD has about 250,000 miles on it. I had a Euro torque converter and new front pump installed when I got my GDE Eco tune at 150,000 miles. Even with the Euro TC I would occasionally get some TC shudder when towing heavy loads uphill but it would stop as soon as I backed off on the accelerator. Didn't happen often. Several times over the last week or so when driving at highway speeds (not towing; just driving) the vehicle will shudder pretty violently, kind of like going over really deeply cut rumble strips. I'll pull over and stop and then when I drive away again everything's fine. I'm just holding a more or less constant speed when this happens, not accelerating hard. Does this sound like a bad torque converter? Trans fluid level is good and fluid looks clean, although it's now got 100,000 miles on it. Any other ideas what might be causing this? It's a pretty severe shudder. Very alarming.
