Their are a few possible causes of this. One their is not enough tranny fluid in it or the kick down cable is not hooked up properly. the kick down cable also runs the vacume to the transmission.

Check theese and give me feed back to further assist you.

SOURCE: Have a 95 GMC truck and the speedometer, odometer,

Check fuse 20 on Insturment Pannal fuse block.

Testimonial: "That's amazing I was expecting some generic answer. I checked it and it is good. I think I'm going to have to bear down and take in to the shop."

SOURCE: 4L80E trans. Lost passing gear/overdrive suddenly

Bad transmission, that's not a good answer. Bring it to the shop [so we can guess around], not a good answer either.

A good mecahanic will respond with something about the solenoids.

I have repaired the 4L80E on my tow truck, I have to do that almost every year, the last time it ran perfectly but when I push the pedal to the metal, it shifted from 3rd gear to 2nd and stays on 2nd gear until I turn the ignition off and start again.

The transmission was totally rebuilded so the answer "Time to rebuilt the transmission" is not acceptable.

I took it back to the shop and the mechanic replaced both solenoids A and B, that was the only thing that hasnt been replaced before, it was just a guess but works

So, I am not a mechanic but my sugestion is to replace the two speed sensors and solenoids before you take the tranny out of the car and be carefull who are you taking the transmission to because guessing is not always the best course of action

The two speed sensors are easy to replace, the solenoids are inside of the valve body but you may be able to replace them without removing the transmission from the truck
