need some trans help..tf3 won't upshift

So I just got done installing a tf3 kit in a valve body I had. Put it in the trans along with an eBay special "super servo" and an hd front band strut... The servo seemed to fit pretty snug in the bore.. enough that I was questioning if it moved free enough...the trans is slow to engage into reverse and low and requires some rpms which would point to the stooooopid servo sticking. But when I drove the car it would not upshift? Any thought's?
