Jeff. Just trying to find the reason your rear servo quit. In your post #262 picture #8 it is clear to see there are 4 threads on the adjusting screw outside of the jam nut. The picture in post #313 is a bit fuzzy & I cant quite focus on the adjusting screw. Did it back off? Or is there something going on with the band or it's anchor?
With regards to your valve body, when you seperate the 2 halves can you post a picture of the main VB where the valves & steel balls sit? Have your TF-2 installation instructions near by.
Cheers. Gaz
