• Some worn valve & pump bodies cannot be salvaged


Due to the complexity of some valve or pump bodies, existing reaming processes can't be used to repair worn components.


The Sonnax valve body reaming fixture allows for consistent reaming results, ease of use and access to bores previously unserviceable with standard bench style tool kits.

Various transmissions locate some valve bores in the pump body rather than the valve body. These larger pump bodies do not readily fit onto the standard VB-FIX base plate. Sonnax offers an oversized pump base plate, VB-06, that allows large passenger vehicle pump bodies to be easily mounted and clamped to the VB-FIX for repair.

Special tool kits have been designed to service a specific valve train bore, and must be used in conjunction with the valve body reaming fixture VB-FIX. Part numbers for these kits begin with an "F-" to distinguish them from the traditional Sonnax tool kits that can be used as standalone tools.
