To adjust the TV Cable skip the book method and do this: Press the 'D' shaped lock button on the adjuster and loosen the cable setting (The black housing that the metal cable is in will move forward). Now, have someone floor the gas pedal while you check to see if the throttle plate is open all the way. Usually they are off a little and will wiggle. Do whatever you have to do to get it open solid. Now, with the pedal still floored, press the 'D' button and pull the cable casing (the black tube) back as hard as you can (putting maximum tension on the metal cable) and release the button. You now have the engine, tranny and gas pedal all in sync at WOT. Mark the cable casing so if for some reason it gets moved you can know where to put it again. The problem with the 'self adjust method' is that it bends things and puts them permanently out of whack. It is also the full TV setting, which is theoretically what the GM method does.
Line pressure will depend on what has been done to it and what tranny is in the car (not always original). In O/D and D you should see a minimum line pressure of @70 (again, depending on what is in it, it could be lower or higher) and when you stall it or pull the TV cable it should at least double, but expect 160- 170 but as high as 200+ to 250 with oversized boost valves. D2 and D1 should stay steady at a max pressure but depends on boost valve but at least 160-170. Reverse will be higher at minimum and max than the drive ranges. I hate to be so vague but there are so many variables. What you want to se though is that line at least doubles and that pressures are steady at all ranges.
