A newbie here. Hope this is posted to correct area. I have a 92 Sammy that I shifted the transfer case into nutural then can't shift it into 2H. The shifter goes into 4H and 4L but the driveshaft doesn't turn when lever is in 4. The guy who built my motor said it could just use a new shifter sheet. Could that be it? Or could there be something major wrong with the T case? Any information will be great.
