I've had the "rumble strip" transmission problem for a few months and multiple trips to the dealer. I haven't posted earlier because my problem and dealer visits aren't much different than other posts here. However I just got my truck back from the dealer today and the dealer said he only did tests and didn't fix anything this time because Toyota is redesigning the torque converter and will replace mine when the new one is available. He also said Toyota said it won't break or cause a problem in use, just has the shudder.

The dealer replaced the trans and converter on mine after a couple visits for tests. The problem wasn't very severe, only happening occasionally, and could not be "induced" very often so detection was a problem. After replacing the trans and converter the shudder happened more often, but made it much easier to replicate so they could do their tests. Their conclusion is that it's the converter, and the redesigned part will solve the problem, but they didn't say when the new design should be available.

I will say Heritage Toyota has been more than helpful, and there has never been a problem or a doubt even when they couldn't get the shudder to happen. They also gladly supplied a rental car to use anytime I brought the truck in. All good things showing Toyota and the dealer are trying to remedy the problem the best they can. But this is the first indication I've had that they actually know what the problem is. Hope they're right and the redesigned converter arrives soon.
