My truck with 40,000 miles on it would shift real hard , with a bad clunk , mainly when I was coming to a stop , and then as I would accelerate . Took it to my local dealership . They ended up changing the valve body . It now has 45,000 mile on it , and is starting to do it again . Going to the dealership again this morning .
It's just frustrating , when you pay this kind of money for a truck , and it has these issues . I hate to say it , but I have owned Toyota's before , with never an issue .
