If you mean the idle speed adjuster, this will have no effect on the shift points. You may need to study up on the vacuum modulator, which screws into the RR of the bottom of the AT, just above the pan. There should be a hose attached to it. Is that hose there and is it connected at the engine end? Make sure the hose isn't kinked, blocking it off. If all this is fine, the VM may need to be adjusted. This adjustment is unique to VW AT VMs. Your AT rebuilder may not have known this. The technique is simple and is covered in the Bentley manual. They should be willing to do this for you if it is necessary. New VMs ALWAYS have to be adjusted, so if they replaced yours (likely) and didn't adjust it (quite possible) then this is likely your problem, IF the hose is in place. Replacement VMs come with a note explaining that they have to be adjusted. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org
