4th Gen Prius, Prius Prime Transaxle - P610 Deep Dive (P710, P711, P810 Similar)
The Evolution of the Prius Transaxle - A Deep Dive into the components, service, and operation of the P610 1NM transaxle. This transaxle is used in the fourth-generation Toyota Prius sold in the U.S.A in the 2016-above model years as well as the 2017 and above Prius Prime (Prius Plug-In outside the U.S.A.) The new 2018 Camry Hybrid P710 transaxle is similar to this P610, but larger to handle almost 45% more torque from the new A25A-FXS direct-injected engine.
