Default 200r4 pressures

So I installed a pressure gauge in to my 200r4 Tran and the needle never stays at a steady reading ,it is all over the place .
Example in park needle bounces from 125 to 175 .in drive is bounces from 175 to 275ish .I took a vid of it but this site will not allow it to load.
Any idea what is causing this .Is it the pump or the T.C.

You need to set the TV cable with a pressure gauge . Also stockish type 10 or 12 vane pumps pulsate. I had a 26 vane in my racing 7004

Pressure seems too high in park, what idle speed? Pressure should not be jumping like that. What pressure do you get with the tv cable unhooked at idle?

About the same .Idle speed was at 1200 ,If I pull TV cable all the way out and zip tied it like that and Drive around the block it does shift a tad better but still shifts so hard it chirps the tires .This is a newly rebuilt trans .I bought what is suppose to be a stage 2 setup .I dropped the pan and checked the TV valve and it is free and moves in and out just fine .
