Transmission trouble in a 2009 Toyota Prius: Looking for tips and experiences

Hey, I recently had a similar problem with my 2012 Toyota Auris. It was really annoying, always this jerking and grinding noise. In my case, the transmission control unit was actually defective. After some diagnostics in the workshop, the transmission control unit was then replaced. It was definitely a serious problem, not as easy to fix as I had expected. But once that was done, the car ran like clockwork again. I would suggest you go to a trustworthy garage and have the transmission control unit checked. Maybe it's faulty in your car too. It's a serious matter, so don't hesitate to have it checked. A repair or replacement could save you a lot of trouble. Good luck with that, buddy!

Hey, thanks for your reply! It's reassuring to hear that it could actually be the transmission control unit and that everything ran normally again after the repair. Do you happen to remember how much it cost you at the garage? And has there been any other problem since then that could be related to this? Any information would be appreciated.

Hey, you're welcome! So, the repair of the gearbox control unit cost me just under 1000 euros. No small matter, but the car has been in top shape ever since. And to answer your second question: I haven't had any problems related to the transmission control unit since it was repaired. The car is now purring like a kitten again, so it was definitely worth the investment. Hope that helps you a bit, buddy!

Thank you so much! I'm reassured to hear that everything worked smoothly again after the repair and that no further problems have arisen. 1000 euros is a bit steep, but when I think about it, it's definitely worth it if the car runs smoothly again afterwards. I will definitely visit a trustworthy garage to have this assessed. Thanks again for your help!
