The Gen 4 engine/6l80 was avail with a manual transfer case, that used a simple switch wired to the E38 exam to signal lo range.... We should be able to reflash the ecm for that T/C.
To get the low range shift schedule to work.
I have included the bcm in my LC9/6L80 swap along with the cluster, (it fits decent in the 80 dash) I plan to use an arduino to supply the needed signal on the can bus for low range signal, it works on the jeep swaps so I signed on. Stay tuned this winter....
Your work in the BCM integration is inspiring, I too will be using a BCM, for all those items, I will also be including the Silverado instrument cluster for full gauges and DIC.
To improve low range shift points I plan to use either an arduino to send CAN messages or use a TCCM to do that job...
Sorry for lack of new pictures my 80 project is on hold for summer, I have posted a few of the pan and diff clearance.
I have yet to Learn how to put a link on my posts to my build.
Stock suspension at is point so no lift.
LC9 5.3/6L80 on the stock TRANS crossmember, engine height was based on...
My 6L80 install with O.E. t/c location require shifter relocation but only about a half inch, easily handled with a piece of alum bar stock.
As for the firewall, I hammered a fair amount, but I wanted a nice bit of clearance and ease of maintenance.
I moved the right rear coil forward a bit as...
I will post pics of the clearance once I get flywheel covers built and installed.
I'll pull the front springs and set it on the stops. I may have to extend the stops to make sure nothing hits.
I hope to save from lifting it in the end. It's much higher at this point but need to get the nose back...
@bloc the late (2013) 5.3 vvt (LC9) Silverado pan clear the pinion flange and driveline with some trimming of the ribs on the side of the sump. (I have no lift yet and have trimmed the blob off of the bell housing and believe I'm close at full jounce to tapping the driveline on the bell...
