It depends on many factors. Is the vehicle an automatic or manual transmission? Is it stationary or driving and not shifting gears? If it's an auto and moving and not shifting the possible solutions are low Transmission Fluid, low line pressure, clutch bands may need adjustment or replacement. If it's a manual clutch may need replacement, shift linkage may be disconnected Please look at the website www.jbody.org for more vehicle information and a great jbody community of car enthusiasts.
Auto or standard?
97 Chevy Z71 truck will not shift into third gear.
If your speedometer isn't working then that gear needs replaced before it'll shift
Replace plastic bushing.

yeah i wonder mines 2002 Chevy cavalier and it just says "err" yeah i wonder mines 2002 Chevy cavalier and it just says "err"
wont kickdown into passing gear
Nope...Maybe if you change out suspension parts...but your tranny and computer will NOT like the change. It wont know how fast it is rolling and when to shift its gears....I can see a "check engine light" in somebody's future....
Could be a linkage problem..
It's Broken ya tard!
could be a rusted out tranny line or a disconected vacumm line.. or possibly the madulator valve went out.. or even more possibly your tranny is shot.. i would try looking at all the lines and if they are all intact try replacing the modulator valve which will cost less than 15 dollars at any auto parts store.. and if all that didnt help it to shift i would scrap it or find another cavalier with the same engine size and do a complete transmission replacement..
transmission wont shift from low to high very good
