Trans fluid level is fine and I did the 2nd gear clutch test earlier this week and I didn’t see anything out of the ordinary with the 3 speed sensors.

Or maybe it actually slipped the trans……
I’m definitely thinking the shop screwed something up or didn’t put the parts they said they did in it. There should be no way I can limp a trans good for 750hp with a truck that makes 400hp

I had the same issue with my built trans when I first got it installed. Atleast ppe did good and shipped out a new tc right away

So turns out the issue was a bad converter. Shop also pulled the transfer case apart to check it over and they also did the pump rub kit while it was apart.

What about the converter caused the leak? Bad hub so pump seal wasn't sealing, pinhole leak somewhere, hub not true, etc??

First transmission I had built had a pin hole in the converter and would leak when it got warm. They had to pressure test the converter to figure this out.

Was it a precision ML white converter? Mine had a bad weld I guess a bunch of them did that came with built PPE Stage V transmissions.
