NEW! VW, Audi 01M, 01N and 01P Bore Sizing Tool
In some VW and Audi 01M, 01N and 01P units you may find that after installing the Sonnax oversized TCC apply valve kit 119940-04K, the TCC apply valve sticks or doesn’t drop all the way into the bore without excessive force.
Get the finish and roundness you need to allow the valve to move freely with the new Sonnax bore sizing tool 119940-BST. This handy tool will eliminate any pesky valve sticking issues by successfully resizing the bore to ensure the correct bore-to-valve interface is achieved.
