Transmisson, I have a 1997 Limmy 4 wheel drive low milage my problem started 2 year ago . IT started when I could not get the key out . The Chev Dealer Ship said It was my battery so they changed IT . That did not help so they said It was my shifter linkage so they replaced it . Now I can get my key out but now I have a nother problem. A month earler I was in the back yard and i put it in 4 wheel drive and put it in low manualy because it was wet, NOW I come to my problem. After worked on it i was in the mountians and started down hill I put the transmisson in 2nd to hold back IT did not seem like IT was doing ITand when I got to the bottem I found out I did not have a 2nd gear IT would not pull. You can put It In Low 1 or 2 and I have no gear push it up to 3 rd and it goes in gear and works like IT should 3rd or Over Drive now They say It Is the transmisson I have took It to another dealer they do not know other than replace It , I have took to 2 other transmisson rebuilder and they both said it is not machanical they agree it works like it should i have all me gears and it changes like it should they said they do not think rebuildind it will correct the problem , They think It Is electrial It does not work In 1 or 2 It try to pull a little but not enough to move the jimmy . I am the 2 nd owner of thes car Itwas owned by a elderly ladie . (so what do you think) I am lost and I have worked on autos all my life I have never worked on auto trans moatly straight drives SO HELP
