Answer 2

its probably in limp mode,this is a mode set when the computer detects a problem with the transmission,it puts it in to limp mode to prevent damage to the transmission and it also stops it from shifting out of first gear,its like a fail safe,but it will have to be scanned in order to determine what caused this too happen,that's the only way to find out,any one with a transmission scanner can find out why this happened,good luck with it.
