While driving up a grade at 50 mph, vehicle began to shake/shudder/vibrate. I had to tramp the accelerator to engage the transmission to work through the situation. This has happened at least a dozen times. Dealer has not been able to replicate the condition. The catalytic convertor is being replaced on 7/16. I do not know if this is the cause of the problem.
