Hi all
finishing a transmission swap in 2009 Express van with 6.0. It was a swap over swap, because originally it was a 2WD with 4l80 transmission, then
converted by Quigley to 4x4 with 4L90 trans and hand (not electric) shifted NP262 (probably) Silverado T-case.
Has E38 ECM Now it has a 6l80 transmission mated to the same t-case thru custom made adapter and intermediate shaft. Used the harness and interface from TrueBlue Motorsports.
Everything works, did a slight tune to to spark tables, tweaked the TC lock DoD and other stuff plus figuring out how to make the TUTD work.
It works, drives shifts....
But i need to adress a 4WD Low. I need to get the ECM know that it is in 4WD low mode. This can be done by grounding the pin 2 at the black E38 ECM. But this only works
with an operating system out of a 4WD truck with floor shifted T-case. So please i am looking for that system or at least a VIN from that kind of truck.
or maybe a segment swap or merging two files together or something like that....
Sorry if some of my descriptions are not correct, but i am more a Mopar guy and chevy world is a bit new to me.
many thanks
