I have a short bus that is now the party wagon. It is a 1995 Vandura 3500 with the 6.5l diesel and i think it is the 4l80e 4 speed automatic. About two weeks ago the 6.5 took its leave. It now has a huumw 6.5l with a 12 volt pump and tps on it. The difficulty is that the shift points are a bit different. I was wondering if anyone knew the factory setting method for the tps. Its on the side of the injection pump and operates on the throttle shaft. I know I can do the reset and drive method to get it close but there has to be a setting procedure. If anyone has the GM method let me know please. I do not have a manual set for this truck. Thanks in advance! Andrew
