GET THE COMPUTER CHIP CHECKED FIRST!!!
I had the same problem, for 1st and 2nd gears. I spent $1300. on a new transmission, only to find out it was a computer chip that was bad -$80 problem!!!
Get a 2nd, 3rd, 4th opinion at different garages so they don't try to cheat you!!
If second is the only gear that does not work, there is an internal failure. The transmission will need repaired or replaced.
Do a VIN search and the VIN will tell you the original options.
The LS has a five speed transmission. Therefore it shifts from first to second, second to third, third to fourth and fourth to fifth. Four shifts.
First Identify what transmission you have and get a rebuild kit for that transmission. Second purchase a Rebuild manual for that transmission, should cost about $30.00 Last and most important take your time and follow the instructions from the manual step by step DOUBLE CHECK EVERYTHING
Transmission valve body dirty.... if you need more help look to loosenut: www.topspeedautogroup.com
The band that controls second and fourth gear has failed. Usually about a $400 repair at a transmission shop.
you could either have a bad syncranizer or the throw out bearing is up
Release the break for a second then move into reverse. works every time on my 97.
I would guess you are low on transmission fluid.
They are the reccomended shifting points for a manual transmission. When you reach 'I', shift out of first, to second, and so on.
The shift link cable could be broken, or the 1st/2nd shift fork, inside the transmission, could be damaged.
a noisy second gear in your transmission is that your second gear might have broken gear tooth which is mostly the problem with my cars.either the second gear on the counter gear or the second gear itself.
