Default shifting into 4th early!!

my car has been shifting into 4th at around 116 at 6500rpm according to hp tuners data log. i am running a 26in tire with 3.90 gears. all the formulas i have used said it should go into 4th at 129 at 6500rpm. my trans recently lost 3rd and 4th gear but never seemed to be slipping at all before it just died. does that sound like a trans or converter problem to you guys? by the way i am running a 4000 vig converter.
