About the UB80E
The UB80E was introduced for the 2018 model year in the Toyota Camry with the 2.5 liter four cylinder engine. Its use expanded to other Toyota models such as the Avalon and RAV4 and then the Lexus ES300. In 2019 the UB80F, an all wheel drive version, appeared in the RAV4.
Four driving and two holding clutches give eight forward speeds and one reverse gear. The UB80E is fully electronically controlled, with six clutch control solenoids, one line pressure control solenoid, one lockup control solenoid and an on/off lockup solenoid, for a total of nine solenoids.
It uses a transmission range sensor, input and output speed sensors and a transmission temperature sensor, all managed by a common computer that controls both the engine and transmission. The torque converter clutch can lock up in any gear. Shift paddles allow manual shifting, and a sport mode gives more aggressive shifts.
Notes
The UB80E is a clutch to clutch type shifting transmission and therefore does not use a one-way clutch nor does it use any brake bands allowing each gear to have two components on and four off.
Do not confuse this transmission with the UA80E which is usually behind the 3.5 liter V6 engine which operates very much like the UB80E including parts that look similar but are not due to dimensional differences that do not allow interchangeability.
