My 2010 4Runner shifts up to 5 th gear when I’m at a slow speed, 20-30 mph. The engine bogs down as you would expect when going to slow for the higher gear….like when you fail to downshift when driving a manual transmission and you slow down. I have to gas/rev the engine to get it to downshift. It started doing this at About 120k miles. I had the transmission fluid serviced, but didn’t help. If I use S mode and manually shift, it seems to work fine. This only occurs if I’m in Drive mode. The engine light is not on, no dash lights are on.
