Slight shudder on take off on my 2009 TRD Sport (100,000) when I bought it, it’s so slight you have to pay close attention. So I had the plugs changed, transmission fluid changed with filter and drive line checked out ok. The guy said drive for a week and see, I still feel the shudder but there is nothing wrong that he could find. He said it wasn’t a worry and come back in a week and he would test drive with me. The only other option was a drive shaft balance, but not sure I want to spend the additional money if nothing is wrong. Thoughts.
