How to control 4l60e on trans dyno?

I would PM performabuilt on that info. I know that they use a home brewed box to do this. We use what is known in the industry as a Tranx 2000 box. Currently under new ownership by SuperFlow Technologies Group. This box works for a lot of different transmissions and is much more sophisticated than what is mentioned above.
With our control box it enables you to control the duty cycle of the lock up function and also the function of the pressure control solenoid. The cool part is you can do this in small increment's of pressure. Like a few psi!
Also there are other tests that can be preformed. One that we use that requires a meter is to check the manifold switch for the temp sensor. You can also check the electronic functions of the solenoids. This is done with a built in meter that reads ohms, volts and amps. We also can check the pressure functions of the manifold switch to make sure that the computer will see the correct data for which clutch circuits are seen depending on where the manual valve position is.
There are other control devises that will literally only have four settings and is kind of old school from what is used in the industry these days. Most good trans shops own what we have. Here is a picture of our test stand. On the lower right side of the picture you will see our Tranx box. Not the best picture but it is all I have.
Here is a link to some more info on it that I got by doing a quick search. Probably describes it better than I did. Here is the link.

Here is another link to SuperFlow Technologies Group website. They make some really cool stuff. Check it out.

He didnt specify who he was talking to or what kind of dyno he was talking about. When I dyno'd my car, my tuner locked it in 3rd for the pull using a laptop and HPTuners..

The manifold switch data is not really going to help you unless you are looking to see where the manual valve is. IMO it is really only used for trans temp and so the computer knows where the shifter is. Now the power flow you posted on the second page will help if you are going to build a box to fire the a and b shift solenoids. The other things you will have to figure out is how to control the duty cycle for the pressure control solenoid and also the pwm lock up function.
Nice charts BTW straight from the hydramatic book. What edition do you have? Vince B

ok now after looking at teh operating conditions( range reference chart) above, i do have a question...
i dont have 1st gear no mater what position the shifter is in for that matter the truck doesnt even move when put into gear.. only has reverse so we know the pump is good (right??)...this is a trans that has been gone through several times that no one can seem to find a problem with...performabuilt suggested it was either the low roller clutch or forward sprag assem...my question is this, say it is the lo roller clutch, should i still have a 2nd, 3rd and 4th gear that work still? or would not having low gear not let the trans get up and go into the other gears froma dead stop?
