The truck is new to me. From what am told and the way it runs it has a programmer. It also has a big head wastegate and gears. The Truck can boost between 30 & 35psi. My problem Is if I lay into the throttle at about 70mph the truck will take off like a bat out of hell, but than when it hits around 80/90 it jerks real bad than and loses 5th gear. It don't lose power or throw black smoke. It just loses 5th gear. It doesn't even throw a check engine light.
So does that mean my tranny is going into limp mode? If so, how do I fix it?
The tranny has an ATS torque converter from what am told (its purple). If it was a gas engine and tranny I would say it had a shift kit, but since am new to diesel and allisons I dunno...
So what do u guys think?
