Please help !!I installed a ls1 into a a checy 4wd reg cab that had a 4.3 with 5 speed and manuel transfer cars.I purchased an auto tranny and electronic transfer case from a 2003 truck but the wires had been cut of the transfer case and i cant seem to find anyone to wire it so the 4wd will work.I would rather use that setup but im wondering is the manuel transfer case from my 4.3 compatible with the 4l60 from the 2003 truck.PLease help
