    I have a 2004 360 F1. When shifting from 1st to 2nd there is a slight hesitation. I can feel the shift, but the engine seems to hesitate for about a second and then engages. This only happens in the 1st to 2nd shift. Anyone else experience this? Any ideas on what would be causing this? Thanks

    I've experienced that on my 2003 360 Spider. I did an F1 fluid change and readjusted the PIS setting in order to fix the problem. Make sure the gearbox and engine are hot before making the PIS adjustment.

    PIS too tight, or worn sychro common.
