Hello I have a 2015 mustang gt with a whipple, broke my trans put new one stock one 6r80 in and changed the filter and fluid on the new one, when the car is cold it drives perfect but when the trans reaches operating temps I get a shudder mostly between 1800-2000 rpm. I put instant shudder fix...

7800, stock engine 121k miles

I dont have an actual boost guage but I have the stock one on the display (vaccum/boost) 2015 cars only and it seems normal same as it was before. how do you check for boost leak
