I have the line to lube valve installed and it's supposed to do the same thing.
Probably not as good tho.
The weird thing is I disconnected the controller and it idles ok in gear. I didn't drive it that way. Just back and forth in the driveway.
175psi at idle tho and 230+ in reverse.
I also was able to lower the idle to 900 which I never could do.

 

That is distinctive how the high pressure made it seem like it loosened the converter. We need a trans expert now to tell us why or how it happens. I wonder if that was what I was seeing with mine without realizing it. I still haven't been able to play with trans settings because of school but I think there is a correlation and we can somehow control the in-gear "pull of the engine" by adjusting something.

 

(Chuckle!) Adjust by putting a manual transmission in. Control then falls to your right hand and foot.

Been following along and enjoying the thread. FWIW -- I debated on engine size/selection when I did my swap last year. Finally bit the bullet and put a 6.2L in. The pain only lasted a short time.

 

Decent power is a great anesthetic, right?

 

Comfortably numb....

 

Nice Pink Floyd reference...

 

the issue here is dry friction material that burns up and splatters the inside of the bellhousing when we use the manual transmission to accomplish this feature. An automatic can achieve partial-slippage without rubbing dry friction is the main benefit so it then falls to us to adjust the performance of the fluid coupling event so that it maximizes whatever features we desire. As far as having control of the car, I see a lot of settings in the HPtuner software and I don't understand half of them but I can imagine there are ways to adjust all manner of automatic trans-behavior, shifting character, where a manual trans is more or less limited to a unique finesse with a single button.
