CNE Posted February 18, 2007 Report Share Posted February 18, 2007 Well, I finally made the hour drive to the nearest 1/4 mile track today. I also ran my best 1/8th mile time today too. 60 ft. 2.02 1/8th. 9.27 @75.36 1/4 14.57 @91.69 Best 1/8th 60ft. 2.02 1/8th 9.18 @75.18 The quickest 1/8th run, my trans would not shift out of second gear so I had to let off before the 1/4 mark. So, anybody know why the tranny will shift if it is left in D, but will not shift 2-3 when left in 3, or manually shifted? Is it a tuning issue, since my tranny is built but I'm still running stock tune? Help!!! Quote Link to comment Share on other sites More sharing options...

That's what I'm wondering, I'm still on the stock tune so I can't change the shift points. The 1-2 shift is fine, but 2-3 shifts too early if left in D, so I tried to manually shift it and it won't shift. It shifts fine if left in D, just too early, around 4800 rpm. The 1-2 is around 5800.

Common performance shift points with stock LQ9 are 5800 for 2nd & 3rd, 5600 for 4th. Quote Link to comment Share on other sites More sharing options...
CNE Posted February 19, 2007 Author Report Share Posted February 19, 2007 So it's shifting too early 2-3, I wonder if the PCM is seeing the stall and thinking it is slipping. It should be holding though at that rpm. Quote Link to comment Share on other sites More sharing options...
