#10T. You get the 4L80E to Tahoe 4L60E transfer case adapter, custom made 4L80E to 4L60E transfer case output shaft, 4L60E to 4L80E wiring adapters, LS1 motor to 4L80E crankshaft spacer and a #10C custom built 4L80E crossmember that moves the transmission mount to the correct position. You saw it here first. Even the best built 4L60E transmission in a heavy 4WD supercharged Tahoe wont last long, a built 4L80E transmission is twice as strong as a built 4L60E transmission.
