1996 gmc 1500 transmission problems

My 96 gmc 1500 want shift out of first gear until u get up to about 30 miles an hour and running about 4500 rpm. Then about 55 it will shift into 3rd gear. The check engine light is not on.I had it scanned and it did not show any codes. I'm thinking it's internal. In the valve body or filter or something But I'm not sure if any body could help me out it would be appreciated it has the 4L60E tranny

It's got 190000 on the truck and not sure on any recent work done to it I bought it with this problem and I think the speed o is working I was told bye a Tecnician that if the speed o meter was workin than the speed o was fine then they told me to see if I had twelve volts going to the pig tail plug on the passages side of tranny and if it had twelve volts on it and still not shifting right then I need to pull the tranny and have it fixed and it doesnt show any codes

that information on a 4l60e would be inaccurate. if the 4l60e does not have +12v going to the trans, it will have 3rd gear take off, and manual 2nd only, and not shift.
does the speedometer drop out at all? from what ive seen with what your describing, 9 times out of 10, its the v.s.s. which depending on whether its 4x4 or not, will determine where the v.s.s. was put.
best thing to do would to borrow a scan tool with a live datastream, and see if the datastream shows if the v.s.s. is reading properly along with vehicle movement. if it satys at zero without coming up with vehicle speed, then all of a sudden pick up, then more than likely its going to be the v.s.s.

It doesn't hesitate at all and it starts off in first and won't shift two second until you get up to about 30 mps and comes out of second about 50 mps could it be the shift solenoids or would the show up on the codes when I had it scanned Thanx for info how could I check the v. S. S.
