My program is set to shift the 2/3 at 6200 WOT and it finally does it at 6700. What causes this? The shift is solid when it does it, and it acts fine on the street. Fluid level is fine, and new filter was installed 300 miles ago (2/3 shift was slow then too).

 

have same problem...

messed with the shift points several times and can not figure it out yet!!
