Stuck in 1st

My 99 Turbo Diesel 3500 would only shift to 2nd if I let off the accelerator. Now its stuck in 1st. I changed the trans output speed sensor, no luck. I pulled a code of 1740. Could it be the governor regulator/pressure switch and how hard is that to change? I also pulled the codes po336-CPK and po-121 APPS. Help zapsurf,Fallbrook,Ca.
