Hi, The 4x4 transfer case has 2 speed sensors in it, They are for the ECM to monitor the front and rear axle speed, Your problem is most likley with one of these sensors, They get contaminated with metal residue as they are a magnetic pick up sensor, You can remove and clean them, They are individual single wire sensors attached with a single bolt.. Take a look, It can't hurt,, Good Luck, Clay.

thanks clay,i did get it repaired with the sensors thanks again
