Customer Question
I need to talk...

I need to talk to a CVT transmission expert. I can't get any answers from Priuschat and I don't want to take it to a dealer. So here goes: My 2010 Prius (87,000 miles) is experiencing problems with the CVT changing speeds. First I changed the ATF fluid (it was black) thinking this would take care of the problem. The car is now at 100k miles and still the problems exists. Example: I will accellerate to 45mph and take my foot off the pedal, the rpms stay high as if the cvt is stuck in the low end. Any ideas?

Mechanic's Assistant: How old is the transmission? Have you checked the fuel filters?

My guess is that it's the same age as the car (7 yrs). Yes

Mechanic's Assistant: Are you fixing your Prius yourself? What have you tried so far?

Yes, I have performed most of the maintenance so far.

Hi Im David, thanks for visiting the site. you need to take it to a shop to have the transmission control module scanned for fault codes. a generic code reader will not read transmission fault codes and normally a transmission fault will not turn on the check engine light. there are many things that would cause his issue and anything short of knowing the fault codes would be guessing.

you're welcome. and the transmission fluid being black before changing it is cause for concern.
