I just had my trans built three weeks ago full billet.
The first 2 weeks no problem, now I get P1756
targeted pressure 35 to 40. When I first start truck it
shifts perfect, once warm and I stop for a light wont
shift between 2nd 3rd until 2900 rpm. If I turn off and
start again, shifts perfect until I stop again.
I clear codes with smarty, but still shifts the same.
I would rather not give persons name that built tran
until I talk to them on Monday. I was just wondering if
anyone else had a problem like this.
