hi, thanks for your comments. I did some testing. First of all, the 3/2 valve itself is brand new.
Second, i put a new vacuum line to the tranny.
Third, i unbolted the vcv, and played with the spring. it was passing no vacuum at all. I banged on the sucker with a wrench, which seemed to free up the spring inside and boom, vacuum again. I've got a replacement vcv on order. I guess the springs wear out on these and they don't return correctly to supply full vacuum. No point bypassing the 3/2 valve if the vcv itself is flawed.
As you can see mine is a very simple setup.
