Dumb Question. Pilot Bearing? Is there a pilot bearing or anything on a 4l60e? Sorry for the dumb question. I bought a motor and trans separate and I have the trans w/ TC, and the engine with flexplate, but thats all.

The inside hub on the back of the crank is occupied by a pilot bearing in a manual car. The very front tip of the trans's input shaft rides in it for support. In an auto car, this area is used for the front face of the torque converter, the center of the converter rides there to support it and to keep it centered. You should not run a pilot bearing in an auto car bc it can interfere with the converter fully seating into the backside of the crank. Not running one in a manual will cause the input shaft to destroy itself in a short amount of time bc of lack of support on the end of the shaft. This will likely take the clutch and slave cylinder with it. Good luck
