This video demonstrates the various technologies in the Toyota transmissions called Hybrid Synergy Drive, showing how braking energy is stored, how the engine responds to slower speeds and sudden acceleration, and what this means to drivers who want to reduce emissions. The video tells more in a few minutes than a two thousand word essay. Watch and enjoy.
After studying the subject, other than an overcomplicated and extremely long Wiki explanation, this video tells it all in a few minutes. Basically, A hybrid synergy drive transmission is a CVT transmission with one forward speed.
Learning more about CVT transmissions is one way to expand the lifespan of your hybrid transmission. My advise would be to follow factory servicing and scheduling and use factory automatic transmission fluid when you have your transmission maintained. The last thing you need is a transmission failure. GotTransmissions.com @ 866-320-1182.
