I bought a Sonnax self-regulating reverse boost valve and installed it and noticed that the inner white spring is loose inside the outer purple spring, it can slide back and forth by about 3/8". I did not notice this when the took the stock valve out. Perhaps it's just because the boost valve is bottomed out in the boost valve sleeve. I just want to make sure I didn't make a dumb mistake.

Also the ATSG manual only shows one spring but mine had two?

 

Anyone?

 

How did you install that stator bushing with the notch and grooves?

 

I do 4l60es all the time, and their reverse boost valve is VERY similar, the inner spring does float around loosely...
