Avalanche transmission won't shift into 2nd 3rd or 4th gear

Asked by John May 20, 2019 at 06:25 AM about the 2004 Chevrolet Avalanche 1500 RWD

Question type: Maintenance & Repair

I have a 2004 Chevy Avalanche. Two wheel drive.
Transmission stuck in first gear. I can drive it but
it'll only go up to about 30 miles per hour Terry and
will Redline if I try to go any faster. It won't shift. I
had both shift solenoids replace. Take it back for
Diagnostics and got a couple erratic speed sensor
codes. Not sure if that would stop the
transmission from shifting
