Let me go to the library tonight, I printed the pressures but when I got home, the sheets were not with the prints, the library has a central location stuff is printed to and it must have gotten lost, be back later.

You those psi numbers ? Would that be high or low ... idk if its suppose to be zero and blue like that one or what but anytime somethings wrong on my obd its red i juss dont know why i get those numbers idling... my guess is secondary pump something is broke ..or channel plate warped or pcs

Here are line pressures, whine noise cause and low pressure cause.

You need to check pressures with a gauge

The 0 psi for 2GR/TCC or torque converter clutch is odd when you look at 91 on 3GR/TCC.  

I found my 4T80E manual by accident today Ill look at pressures.

I don't think this is electrical

Check the channel plates closely for blown out gasket material I found this doing my ISS speed sensor.

No deff not electrical. And i already got everything off and taken apart and radiator out to drop motor and trans . Im juss gonna open up the side case and inspect the pump system . And i replaced the bonded gasket on the lower valve body but thats the only gasket i replaced still gotts drop the trans and open it

I didnt find any pressure info in this manual, Ill check the 96 service manual, I know its not a 06 manual but I want to see if I can identify the pressures you posted above

I know, I am concerned about the 0 psi pressure above and whether that means anything

Ok I found something, these adaptive pressures should be zero or close to it when the tranny is new.  These are adaptive pressures used to offset slip, if slip or worn part is detected, the pressure is increased to stop the slip.

You got those pressures on a lift correct?  Was the battery ever disconnected before you obtained those pressures?, 

I am trying to determine if these pressures were 'set' from driving the car or from when you had it on the lift.

As you can imagine if these adaptive pressures came from when the car was on the lift, how trying to drive the car on the road would induce slip, those pressures would have pinned at 127 psi

Did you read the description of WHINE above?, the whine can determine pump issues, based on how it whines.  There is a filter after the pressure solenoid that you need to inspect.

So this means what exactly my tranny is slippin ? Because of somethin right im going to inspect the solenoid and pump hopefully a repair will fix it .

I think this confirms you are skipping.  When you disconnect the battery, these adaptive pressures return to zero.  

So the question is, did these set on the lift or while you were trying to drive the car.

Regardless, you are slipping, though.

Can you describe the whine, did it vary with RPM?

Ive had the battery disconnected multiples times. The whine is as soon as i start the car and its there right in the side case and yes it matches the rpms.  Last time i had the car runnin it whined in park stopped in reverse and whined again in drive. That was a first cuz normally it juss whined until i turnee the car off

Then as you saw varying with rpm is related to the pump system.  Keep in mind that the pump might be good, but, filters are clogged eith debris leading to the pump starving it

You can disconnect the axles and left strut and drop and tilt the carriage to the left, disconnect the steering shaft (one bolt) so as not to bend it

Use 4 long 'all threads' in the 4 carriage bolt holes and use washers and nuts to drop it down, I think they are M11 or M12, but I forget., check.  The all threads should be about 12 to 18 inches long.

I actually don't mean those filters, I mean the strainers that are little tiny wire cones usually that are after things like the pressure solenoid motor.   I will look around, for strainers or pathways that can starve the pump and cause it to cavitate.  

This photo was from when I got into my side pan to change my Input Speed Sensor (ISS), you see the all threads, into the carriage bolt holes, by backing down the nuts (while making sure you aren't backing out the all thread, you can slowly and in control drop the carriage.   Notice that the car is held up by good jack stands.  BE CAREFUL and SAFE.

I disconnected the exhaust system before the CAT also.

Here is my ISS speed sensor thread, from when I tilted my carriage to get into the side pan.  My screen name back then was Scotty.

There are other side pan threads ill link to.
