2017 Silverado E92 vss shows 158mph

[kgraves]

I have a 2017 silverado engine and 6l80e trans (from a 2014-16 truck) in a swap and the VSS displays 158mph. I reprogrammed the TCM with my MDI2 and SPS to the VIN from the ECM and checked the VSS wiring from the sensor to the ECM.

Any suggestions? VSS 158 MPH.hpt

Thanks

If this is a 2WD 6L80 the OSS/VSS is in the transmission. In factory form, you have this speed sensor data going to the TCM, then on the CAN bus to the ECM. It then goes to the BCM and then the IPC.

How is your set up wired?
