Is the transmission in the 2006 Tundra supposed to stay engaged while decelerating/coasting? I've been driving my parents' Tundra all week and it seems like if I take my foot off the gas it drops speed a lot quicker than I think it should. I can feel when it downshifts while I'm coasting too. It's a strange feeling compared to my 2001 Silverado that seems to be able to coast for a long time without dropping much speed. It could be normal, but it seems like the Tundra encourages staying on the gas longer than in my truck. I wonder if that could be contributing to my 4.8L V8 getting 17mpg where their 4.0L V6 is getting 16mpg. It has been in OD the whole time too.
