The Toyota U340F 4-speed automatic transmission was assembled at the Japanese plant from 1999 to 2014 and was installed on all-wheel drive versions of such models as the Probox, Porte, Ist and Corolla Fielder. This gearbox was paired with the 1.5-liter 1NZ-FE power unit.

Disadvantages of the Toyota U340F gearbox
- This is a fairly reliable gearbox, but it does not tolerate frequent hard starts and wheelspin;
- With active owners the lockup clutch wears out quickly and the solenoids get clogged;
- Driving for a long time with a worn clutch, vibrations destroy the oil pump bushing;
- At high mileage the Teflon rings often wear a groove in the rear cover of the gearbox;
- The oil pressure in the system then starts to drop and the clutch packs begin to burn.
