my buddy put his truck back to stock with a stock 60E. the truck starts out in 3rd gear because for some reason my shift solenoids are not turning on. However with my scan tool i can go into the DVT(f12) tab and command both of them on. When i do that the truck starts off in 1st gear like it is suppose to. So to me that tells me that the solenoids are not bad and it must be something else.

its not throwing any codes. does anyone have any ideas as to what it could be? something in the tune maybe?
