Ok so long story short got my hands on a HD T-case from an 03 slammed my case in its place just a few bolts kept what I could. ( new case in junkyard bound wreck my case busted chain link slapping case) I never slowed down to see that the plugs on the encoder were different. So here I sit 2001 2500 Suburban 8.1 with a brand new ( built in november of 19 case and I cant shift it with encoder. I cant find the schematics on line for either truck, I have re-pined the new one plug harness(03) with the female connector from from old harness(01) up at the fender. No Joy.... I still have a 6 pin (01) that is replaced buy a 3 pin (03) I have no idea what, where, or how. I CANT FIND A DAMN THING ABOUT THIS. Please any help. I NEED SOME JOY!!!!!! Btw... Im full time RV well travel trailer and my tower is my burden.......

 

Is any one out there?????

 

Can't you just replace the shift motor?

 

no I wish the input shaft from motor to case is different 01 round end rectangle. 03 is 12point round.

 

Is it possible to just replace the motor? I have a 2000 t case shifter that is 4 wire, but looks like the motor is removable.
