I just found my old TF2 instructions. There the TF1 kit is also covered:

The stock PR spring is used, setting is set as stock BUT the throttle valve is only cut on TF2 and it's spring is pink or yellow. In my VB the throttle valve is cut like on TF2 and the spring was silver/chrom. And it also writes to leave the 1-2 shift ball out on only TF2 kits. On mine that ball is missing.
I also got no hole in the line pressure limit ball and the spring looked to be original.
So I GUESS someone here didn't do his homework when installing the TF1 kit OR this is another kit that is similiar to the TFx kits...
