Ever since we bought our 2015 RAV4 at 15,000 miles, the transmission has regularly disengaged at hilltops, allowing the engine to race before downshifting after cresting the hill. I brought this up to the service advisor at 28,000 miles. He said this was normal behavior, not to worry. We're...
Delay gear shift, but only in the morning when the car is cold and only in the first gear. once the car warm up 3 or 4 minutes it works fine all day.
I changed the fluid and filter, but still the same problem.
