Setting line pressure in my 48re. Just have it on Jack stands atm, in D at idle I'm seeing 125 psi? When it shifts to third I'm seeing 190. I have the cooler lines looped but that shouldn't affect line pressure. Screw is 1/2 turn from flush.

With the pan off cycling the key the arm goes against the stop then just goes back a hair. Cycling the pedal I have full movement of the throttle valve.

I used a pdd DIY kit on the vb. Everything went together smooth. Goes into all gears fine.

At stall in D I was getting 140.
 
I put a long hose on it and did some testing and i couldn't get more than 190 psi line pressure I think its fine. it went down to 95 or so at idle now. Gonna order a cooler so I can road test it now.
 
Running 170-175 in od just like I wanted. Still 110 at idle maybe cause of new pump gears?

Having an issue with tc not unlocking while slowing down in tow/haul. Throttle pressure adjustment maybe.
 
It also doesn't want to downshift until I slow down with tow haul off. Transducer doesn't have that many miles on it. Think it's the throttle pressure adjustment. If I floor it at 60 it doesn't downshift sometimes unlocks for a second then locks back up in od.
 
I've randomly got a hiccup in OD 3 times today, revs up like its downshifting, but it's not slipping, then goes right back to normal. Wont slip under wot. Did a few pulls today worked great.

Has the GM solenoid already, failing transducer? It's still got the plastic one
 
It does slip now in 1st and 2nd forward clutch seals probably blown line pressure still good but 2-3 bind probably not helping it
 
It would slip in 3rd if rear clutch was slipping, text if you want quicker responses 7045269366
