Is there a possibility that the shift servo could be the culprit??? I am having the same problem with an 89 k1500 and I have changed the governor and now it shifts great into 1st and 2nd gear...It even chirps the tires when I step on it but I can't get it to shift into 3rd or Overdrive...I have been playing with the tv cable, which some people call the throttle valve cable, which I believe is the vacuum cable...But who can say for certain...Anyhow...I am worried that the clutch pack may be out...hehehe...But on the transgo jr shift kit that I purchased it states that it will correct the 2-3 cutloose...Anyhow...Who can say for certain???Maybe someone in here can shed some light on 2-3 cutloose...The fluid was quite dirty when I changed it but there was not much metal on the magnet...I sure hope the shift kit will remedy my problem...Or could I just remove the shift servo and clean it up and slap it back into the tranny??? Only time will tell...
