Hi,
I have a 2015 L96 6.0 with 6l90 transmission out of a 3500 Silverado. It uses an E78 ECM.
I bought an L96 E38 harness with T43 TCM connector from an Express Van.
The question: would a 2014 E38 from an Express Van running a 4.8 6l90 work? I?m assuming I would need to segment swap it? Or VIN OS swap it to a 2015.
I have someone that will VIN OS flash an E38 for me. Would a 2014 E38 (hardware) work to flash to a 2015 E38 OS, both Express Van?
My biggest concern is the TCM. I?d rather not flash it and risk bricking it with an OS change. Instead, I?d rather get a 2015 E38 OS to match the transmission.
...the 2015 Express Van L96 also isn?t listed on HPTuners compatibility list.
