[QUOTE="Frank_C, post: 597373, member: 3580"] I started a thread about a similar problem with my PI converter a few weeks back. New pumps are $550-$700 from what I could find. Mine slips bad enough, that the tcm commands full unlock almost immediately. And my line pressure checked out fine. I called PI and asked what the purpose of the spring was. They said it was to keep the pump from bleeding off pressure in the converter. There was a specific name for the valve, but I can't remember it at the moment. They also said the TransGo kit comes with a spring that raises the pressure limit before it bleeds off, but the spring that comes with the converter is stiffer, and should handle a bit more pressure. Might've been called the converter pressure limit valve? My truck is still out of commission from this issue. It slips on every tune other than Eric's tow tune, and I have IDP v3.01, and Gearhead's tunes. [/QUOTE]
