Title: NP203 speedometer leak
Post by: Destro on January 24, 2007, 12:36:00 am

Transfer case is leaking at where the speedometer hooks up.
I cant find anywhere that sells the seal or the whole speedometer piece. Does anyone know where to get these parts or a trick to seal it up? Has this happened to anyone else?? I guess GM discontinued the part and all the chain stores don't have a listing.

So the speedo plugs into the transfer case?  I have an inop speedo as well.  It seems fine in the cluster so I would imagine the cable is bad.
