how to change shift cable on 04 trailblazer
I had the same problem. I found that my 2nd and 4th gears were worn to the point of non existance.
Is it an automatic or standard? automatic and fluid is not pumping when engine is running
im having the same problem now as we speak. i was told it was the shift solenoid located in the transmission.
Stick shift or automatic? any other gears work?
did the clutch cable come off? (if its a manual) that or there is a problem with the transmission.
You should check for codes first. it is an electronic transmission and changes gears based on information received from various sensors. If the throttle position sensor is bad, it will not shift gears correctly. mine wouldn't shift into second until 30 mph and wouldn't shift into 3rd until 55 mph.
If your car/truck is having problems shifting, it may be your transmition. You may want to get that checked out.
