Expert:  edhunt0r replied 2 years ago.
The speed sensors are located onside the transmission and directly connected to the transmission control module which is in the transmission pan.You will need to contact the Manufacturer of the spreader to see if the have a way to adapt to newer vehicles that don't have access to the speed sensors.

Sorry for the delay in responding. I was in an area with poor internet. And the system had me locked out. Your vehicle had a design change. Below is an explanation of the change.Your RPO is: AVF - **UNIT BUILT AFTER AUG 14,2014MYD - 6-SPEED AUTOMATIC TRANSMISSION NQF - ELECTRONIC SHIFT TRANSFER CASE The RPO-AVF designation was used interim 2015 MY to provide a break-point for a variety of changes that occurred for K-truck applications. The transfer case digital speed sensor change is just one of many within the RPO-AVF designation. Refer to applicable service bulletins for additional information.Interim 2015 model year for Magna HD NQF and NQG transfer case applications with Duramax engine and Allison transmission (RPO-MW7), a NEW design digital speed sensor (4) is to be implemented.Non-AVF applications will continue to use the threaded-into-the-rear case design speed sensor (1). Applications with RPO AVF will include a non-threaded push-into-the-bore design speed sensor (4) that is retained by a bolt (3).To differentiate between digital speed sensor (4) and non-digital speed sensor (1) applications, the RPO AVF is used to identify digital sensor applications. Vehicle Speed Sensor (VSS)There is a VSS mounted to the transfer case on the rear output shaft. The VSS is a PM generator. The PM generator produces an AC voltage. The AC voltage and frequency increases as speed increases. The VSS is an input to the powertrain control module (PCM). The PCM sends this information to the transfer case shift control module via the GM LAN serial data bus.

Daniel, I appoligize for not getting back to you. I was in a rush for this information an when I did not hear from you till 10:46 pm . I already had the issue taken care of through a GM upfitter site. As you know time is not on our side in repair and new install. What I am saying is ,I thought the information would have gotten to me sooner. I am not a happy User of your web site. Thankyou, Scott

Hi, Sorry for the delay in getting you the proper info, I was in an area with limited cell service and internet service for awhile.
