Just like the title says... the truck won't shift out of 1st at any throttle position unless I take my foot completely off the throttle, then get back on it. Once it's out of 1st and past ~28mph, it shifts 2-3 and 3-4 completely normally. It will try to kick down into 1 if I go WOT/WFO under about 45mph. And if I floor it at low speed, it'll hold 1st all the way to redline, and won't shift.
Is this a governor issue? I replaced the solenoid and sensor back in 2010 with dealer parts. I'm ready to order the Suncoast governor kit, I just want to make sure it's (probably) not something else...
