Welcome, I'm Chris (aka Moose).

  • Although I work here everyday, please understand it is not all day and rarely morning time.
  • To get the most from me and the best experience, please give me the best details you can.
  • The website will offer you a phone call option for more $$. Some I do fulfill and some I do not.
  • Thanks, let's get started.

Most likely there is a connector to the transmission unplugged, damaged or a wiring crushed concern. The speed sensor is on the rear of the transfer case and the gear position indicator is on the transmission. Use this wire diagram and check those wires related. https://www.dropbox.com/s/guofkdof2n61bfe/42vss.pdf?dl=0

Now that I have posted a partial or complete answer, you will see you can rate me. The deposit you have already paid is not transferred to me until you rate me. I would like to receive nothing less than 5 star excellent ratings. So if we are not there yet, please reply and let me help more. If you're not pleased, let me know because rating bad does not result in a refund, there are better options. Rating now will not close this post nor prevent replying. Thanks Chris
