So, when it comes to automatic transmissions I am semi-literate. I know enough to know that I don't trust them. Now I've got a strange problem that I would like to run by you guys. My 2013 RAV4 in my sig has started to shift strange. I drive 120 miles round-trip from Lynchburg to Charlottesville VA and back for work each day. If you are familiar with Route 29 you'll know there are a ton of rolling hills. Recently, when going up hills I have started to notice one of the two scenarios that are both disconcerting: Scenario #1: While at highway speeds, the car will downshift to 4th going up a hill. When it gets to the top, it will either shift to 3rd or just free wheel (hard to tell) and rev to the limiter at 6500 rpm, then drop back into 5th or 6th. Scenario #2: Same situation, but the car shifts to 3rd over a larger hill. At the top, it will shift from 3rd, go to the rev limiter, drop to 4th, go to the rev limiter and then drop into overdrive. It is shifting like this almost all the time now at highway speeds. I had the fluid changed w/Toyota ATF and Lubeguard Red at 38k. It sees mostly highway miles. I will occasionally tow a small utility trailer with it, but I keep the loads very light and use the "Sport" setting to keep it out of OD. What do you think is going on? Any help would be greatly appreciated!
