First post here! I have a 1999 GMC Yukon SLT 4wd with autotrac and ltd slip.
I was driving down the highway the other say at about 70 mph and notice my rpms changing erractily. Well since then it has gotten worse. The truck now wont go over about 45 and that is with the gear selector in 2nd... Most of the time I have to put it in 1st to get it rolling. Reverse still works fine but the other day after continuing to drive it messed up i almost completly lost every gear. truck would barly do anything. On trans shop said it needs a rebuild other said the transfer case is locking up. Been reading forums and im thinking it may be other things now but i havent found someone with an identical problem... But I hope you guys can help me and maybe I can get this thing running right again. thanks in advance.
