Hey guys, iv got a z71 Tahoe and iv lost 3rd all together... I have tested the shift solenoid for 3-4 and its good. I can manually shift up to 3rd. But have nothing. 4th is fine and is everything else. The only other thing is every so often when I start it she kicks the transfer case into 4h or N. I'm about to pull trans out but am hoping I am wrong and I don't have to rebuild it. Is there a known sensor that causes this problem? Thanks.
