Hey guy's school me on the electronic shift controllers. I have a 2004.5 Dually with a ATS performance transmission and shift controller on it. I leave the controller off but my transmissions shifts wierd. As long as you drive normal it shifts fine but when you keep trying to accelerate it shifts into high gear and kind of jumps when it shifts into what I guess is overdrive or the torque converter locks up. It never shifts into high gear until you are running 50 miles per hour. I know how to adjust the old tv cables but is there any adjustment I can do on mine. It really feels like too much pump pressure until I let off the gas pedal. Any advice would be appreciated. Joe

 

if it was mine i would be calling ATS since it is their tranmission they should know how it works and if there is anyway to adjust it.
