Hmm. Well, perhaps I should retitle this thread. The shudder's almost entirely gone! In fact, the day after I started this thread the severe shudder stopped happening almost at once. It's been five days now. It still occurs once in a while, but the severity and frequency of the shudder have greatly reduced. I can't tell you how wonderful it is to start the car, push down on the accelerator and have it smoothly accelerate to 40 mph without the slightest shift or shudder.

Perhaps I'm just not well read enough on this car. Does it have a "breaking in" period? If so, I guess I can consider mine broken in at 1,500 miles.

Anyway, I'm thrilled to say that the shudder is just a shadow of its former self and my buyer's remorse has vanished along with it. I love this car!

Moral of the story? Got a problem with your TCH? Come on here and gripe about it and the next day your problem will vanish!
