Q: How to remove and install a Chevrolet C1500 and K1500's transmission?
A: Take out the transmission. The manual transmission of your car will also need the clutch and pressure plate to be removed. Penetrate through the driveplate (for vehicles with automatic transmission) or into ring gear of starter (for manual transmission vehicles). This way, you will lock the crankshaft and then remove the bolts that hold it in place. During loosening/tightening of these bolts, hold onto the crankshaft to keep it from turning. Since this is quite heavy, let it rest on another part as you remove the last bolt. Pull back directly on the flywheel/driveplate until it comes off from the crankshaft. Installation is similar to removal. The driveplate should be installed with torque converter pads facing towards the transmission. Ensure that you have aligned hole in flywheel/driveplate with either dowel pin or untapped hole in crankshaft. Use thread locking compound on bolt threads and tighten them to specified torque in a criss-cross pattern.
