need some trans help..tf3 won't upshift

I haven't done a tf-3 kit but it's my understanding that it converts it to full manual shift. I think their point is you can reverse it and put it back to auto shift as opposed to some kits that require major mods that can't be reversed. If you've air pressure checked it the problem must be low pressure or something not installed right in the VB. Do you have a pressure gauge to do some pressure checks with?
