I just got a 2010 Tundra and when I put the truck in "manual" mode it always says it is in 4th gear. the tranny does not shift though, no matter what gear it is actually in. it will also not put the tranny in a higher gear than what it thinks it needs to be in, so it pretty much is doing the automatic shifting anyway. all i can do is down shift with it. is that normal for the tundra or should i take it in?
