Default 700r4

I've just completed my 700R4 conversion, and everything seems to work fine.
Apart from the lockup. The 4th gear switch stay closed at all times. (the 4th gear is working ok).
Before assembly I tested the switch to open at 30psi. Anyone who can confirm if this is correct?
If so, then I assume the hydraulic pressure might be to low?

I've hooked up the TV cable to my stock Qjet so that the TV plunger is fully seated at WOT.
Is this ok or do the Qjet also need an adapter to alter the length of pull on the TV cable?
(I will test with a manometer asap..)

TV fully seated at WOT is what my tranny guy recommends, and from the feel of my shifts, I think it's correct....

For proper operation and longetivity, your TV cable geometry should look something like this:

Thanks all!
According to my measurements the Qjet should comply to the correct geometry. The radius might be slightly to large which may cause too low idle pressure.
Have those of you with Qjet had to decrease this radius?

The oil smell a bit strange, guess I have to do that pressure test right away...
