These mid generation changes and lack of field testing is exactly why things like this happen. This is what happens when decisons are made by businessmen and not engineerss.
The 6 speed was driven around the world for 5 years in a demo 200 before being released. I doubt the 8 speed went through any rigorous testing.
I wouldn't go that far. I have no doubt that Toyota tested it extensively before plopping it into the most reliability-conscious vehicle in their line-up...but it does sound like something was missed if reports of multiple transmission replacements are to true.
