Since shifting causes lots of wear, I just put mine in S4 and wait for the top of the hill.
I hear that installing the supercharger gets rid of this issue. 
Some sort of aftermarket programming change may work as well, but I am planning on staying stock so haven't explored that option. |
I know it’s not an option for everyone but with a supercharger the transmission never unlocks out of 5th. It’s so much more enjoyable to drive. Last summer we drove down to the Smokies and the 4Runner always stayed in 5th, no matter the size of the grade. I’ve driven the same path with no supercharger and it constantly hunts between 4th and 5th. I used to just leave it in 4th on grades to avoid all of that. Before the 4Runner I had a first gen Tacoma and it did the same thing. Then I would just lock or unlock overdrive. It’s just something I had become used to driving a Toyota.
