BMW 3-Series Automatic Transmission Valve Bodies

A valve body is a part of the automatic transmission that carries out regulatory functions. While receiving pressurized fluid from the oil pump driven by the torque converter, the valve body is actually what allows the automatic transmission to feature that high degree of automation. Due to its complexity and pressure that the assembly works under, the valve body is generally considered a rather capricious part that sometimes becomes a weak link letting the entire system down.

Your BMW 3-Series is a quick car featuring pretty decent performance, unless the valve body in its transmission is worn-out. Any issue compromising the capability of this vital AT component can lead to an array of unfavorable changes in the vehicle's behavior. And there is, unfortunately, no other way to get the problems fixed except for the replacement of the malfunctioning valve unit. Most recent generations of the 3-Series employ ATs from ZF Friedrichshafen – a respected and well-known car parts manufacturer. And in order to address the issue, such an assembly has to be repaired using only the highest-quality components. In our BMW 3-Series automatic transmission valve bodies & components inventory, we have quite a number of them.
