    So just to clarify: You are having problems shifting from gears 3 to 4, 4 to 5, and 5 to 6? But downshifting (6-5, 5-4, 4-3, etc.) is OK?

    Hi Kent

    Thats correct ....the downshifting works perfect!! The problem its upshifting 3 to 6.....

    You also say that sometimes the upshifts from 3-4, 4-5, 5-6 work?

    Is the QS actually making any ignition cut?

    If you have a multimeter tester, test the quickshift sensor to make sure that it's making a full connection on the upshift. It should have a full continuity reading when you apply significant pressure to the sensor; if it's cutting in and out, then it's a bad sensor, but if it's staying full on, then that rules out a bad sensor.
