The most common problem associated with the drive gears of the oil pump of the FORD 10R80 transmission and the similar in design GM 10L90 transmission is noise during the operation of the transmission from the torque converter. But according to the assurances of the manufacturers themselves, the noise is associated with the design of the gear teeth, namely the rectilinear arrangement of the teeth. This design of the teeth is less durable than helical gears, since the contact patch in gears with linear teeth is smaller, which in turn affects strength.

There are cases when the teeth on the drive gear are damaged, which ultimately entails the complete destruction of the gear. This problem is more common in transmissions installed on vehicles with diesel engines than on gasoline versions.
