1-2 shift harsh
Posted: Thu Apr 23, 2015 4:30 pm
1-2 shift feels like it slips then bangs into gear at 3/4 or WOT otherwise shifts fine. I have tried hard and firm tunes no change, also messed with pressures increased and decreased no change. I have heard it might have something to do with speedo calibration? it's off 2-3mph according to gps. I want a hard shift but with out the slip- bang into gear. Im also hearing some knock at WOT between 4k-5.5k, on 91 tune running 93 in the tank. I know I can just retard timing a few deg's or add fuel there. Main issue is the shifting...any help would be great!! thanks
