The range of 4-speed of automatic transmissions А340 (also known as AW30-40LE /-70LE according to Aisin classification) has been on the market since 1985 on RWD and 4WD Toyota Land Cruiser with the engine capacity from 2.5 up to 4 liters. The А340 unit is a middle class transmission which stands next to the range А40 of the class "mini".Toyota used the А340 series for all other powerful cars: Pickup, 4-Runner, Mark II, Hilux, Hiace, Previa, etc.There is a large number of modifications of А340 Series for engines with 2.5-3.2 liters capacity.The AW30-41 modification and 30-43 is still in demand as not expensive, low-maintenance, robust gearbox for "work horse" cars.

Technical issues and repair guidelines

Each modification in this transmission family had some updates in the electrical part (linear solenoids) of the valve body and torque converter.This transmission is quite simple, balanced and has a huge resource reserve. The repair of this gearbox usually takes place in cars with high mileage and includes replacement of worn-out spare parts. It is almost always the case that the torque converter of this transmission is handed in for repair. Operating with the worn-out lockup leads to the output shaft beating and excessive side load on the pump, seal, and bushing.


Operation of the A340-equipped car with contaminated fluid results in wear-out of bushings through which the oil leaks out leading to main pressure losses. Almost all bushings are replaced together with rings and gaskets included in the repair kit. Firstly, the pump bushing gets out of service. Because of damaged bushings the pump may have performance efficiency problems leading to the oil pressure shortage in packages, therefore friction components of packages primarily involved in operation start slipping and get burnt.Commonly, frictions (with steel discs) of Forward package get burnt. The brake band is standard for all modifications. It is replaced when the car comes to repair with burnt fluid. The replacement of solenoids is common for old cars (produced before 1998).
