i recently purchased a 1995 k1500 4x4 with the 4.3 auto. The truck had the orignal motor that runs excellent doesnt burn oil or leak a drop. My problem just started with the tranny would suddenly stop shifting ang stay in 2 or 3. When this happens the truck wont shift up or down even if you try manually. Sometimes if its stuck in 3 and go 2 second it will go to 2 and wont go back. If i stop the truck and put it back in park and shut it off for a minute and restart it will be fine again till i have to slowdown it get hung up in gear. The tranny was replaced at 180000. It seems to me to be a electrical issue thats not telling the tranny to shift as there will be days its fine. Do you think it could be the transmission shift module???Please help

The module is a possible cause. However, it will usually cause the check engine light to come on. It could deal with a shift solenoid.

Let me know if the light is on.

Light isnt on but a friend of mine hooked it up to his computer and it read a speed sensor error?

He said that it didnt make sense as the speedometer was working.
