Noob question 727 really low shift points

Dave Haertel said
Ok, so when I got the car, I got nothing to go on, literally guy lied and said it was a 360, it's actually a 340, told me the trans was perfect, drove it up and down the driveway, but when the car was delivered, trans fluid was empty, NSS was backed out almost full, so I've got nothing to go on with this trans, or the differential for that matter. I'll crawl under the car this evening and get a stamping number or something so I can at least look this thing up and make sure of what I have. I'll post more this evening. It's parked now, so it won't go anywhere until this is done, I put about 50 miles on it between work and errands yesterday, hopefully I didn't trash the whole thing.

Side note, this was in a shop, they had their hands in it, pulled the pan and reset the NSS and refilled it, wouldn't this be something they'd check and let me know about? If it's supposed to be there, based on the type of valve body, that would drum extra labor for them, right? Just thinking out loud.

I'd be surprised if I found a shop that knew what it was (or wasn't):D
If you do a Google search you can find lots of images showing what used to be there.

I would get under that thing, or look down there with a flashlight and see if it's got the lever and what is or isn't there and take it from there.
On the trans, there should be a lever like this fingers pointing at.
Some had a knobbed stud like this and some have a hole the end of a rod goes into.
In any case, this is the throttle pressure control.
(the farther back to the rear of the trans the more pressure it gives in the trans to make shift appropriately timed and holding pressures higher for clutches and bands)
This is why it can burn them up if nothing is hooked up, because the trans thinks the car is just sitting at idle and doesn't need the raised pressures.
