Started to build the trans again, since the roller bearings arrived, and we got the friends GN to start up. So busy times are gone for now.
I have now gone trough the whole valve body and the th400 kind of "stage right" will not work.
The problem is, that the manual valve is operated from the other end opposed to th400 and therefore a new shaft that will block the reverse->exhaust flow at 1st is not simple to do.
The shaft could be lengthened to have the desired effect, but then it would want to go trough the oil pan at park.
For feeding, there is a double acting check ball before the rear servo release that allows pressure there either from lo or from reverse. That check-ball seat could be tampered to get it to flow from lo to servo release and reverse and from reverse to servo release.
But this feed is trough the modulator, so it will see lower pressure, so in worst case, I would have to ditch the modulator altogether. Not a big problem for a strip car only.
Am I way off the path with this thing?
