Comparing the pumps on Ford 6F35 generation 1 and 2

The change

For the 2013 model year, the Ford 6F35 transmission received a high-volume pump which increased the intake channel in the stator shaft support from 0.432” to 0.520”. The pump body intake channel was also increased to the same matching dimensions.

The reason

Higher pump volume was required to accommodate the 1.5-, 1.6- and 2.0-liter turbocharged engines. Parts affected include the stator shaft support and the pump body.

Interchangeability

Neither of the generation 2 pump components are interchangeable with the previous design due to bolt pattern change, filter dimension differences and front seal retention.
