Transmission problem
2002 Chevy Silverado V8 Two Wheel Drive Automatic 140000 miles

I have the 6.6 l deisel with allison trans. There is no shifting in drive, like it's stuck in 2nd, no low and no 3-4. I got reverse. Thinking it's a transmissiion solinoid, but where is it located if I'm correct. Am I?

Do you

You need to have it scanned for trouble codes with a Tech 2 or equivalent scanner. You could have a bad gear selector switch or a bad solenoid.
Let us know what the codes are.
