We installed 2000 suburban transfer case in our 2004 Z71 4x4 Chevy tahoe and our Tahoe still won't run. The encoder motor is the only difference in the transfer case. My husband the encoder motor so it would work and reinstalled the transfer case. Started the Tahoe up and still won't go anywhere. When shifting back to park, reverse makes an awful noise. Any help would greatly be appreciated. Thank you for reading.
