The German manufacturer of auto parts and parts ZF is known for making automatic transmissions. They are installed on many European cars. The 3HP22 automatic transmission began production back in 1973. Due to good reliability and durability, the units were used on various brands of cars until 1990.

The 3HP22 three-speed transmission was mainly intended for German cars manufactured under the BMW brand. According to reliable sources, automatic transmission was used on them until 1984. Despite the fact that the development was carried out in the 70s, the engineers managed to create a reliable mechanism.

 

Features automatic transmission ZF 3HP22

Over the years of operation of the 3HP22 unit, accurate statistics have been collected. According to the data obtained, the average mileage is 200-250 thousand kilometers. The three-speed hydraulic automatic transmission is highly reliable. During the first 200,000 thousand km, the car owner should not worry that it may fail. In order to maintain performance at a sufficient level, it is necessary to regularly replace the lubricating fluid.

Since the introduction of the 3HP22 automatic transmission, which replaced the 3HP20, it has been used by the most famous European car manufacturers. The device is able to perceive large values of torque, up to 320 Nm. Due to the robust design, the automatic transmission was installed on cars with an engine capacity of up to 3.0 liters.

Despite the high reliability, the 3HP22 modification still fails. Most often this happens with the front clutch pack. As a result, the car can only move in reverse.

Drawing a conclusion regarding the 3HP22 automatic transmission, we can say that the engineers of the 70s of the German company ZF created a truly reliable unit. It is highly durable and is able to "pass" hundreds of thousands of kilometers without significant breakdowns.
