Knocking in any engine is really bad. Check the engine oil level. Isolating these noise are difficult. If you can start the engine if you disconnect the torque converter or clutch you can rule out the trans from the engine. If the noise is still there then your knockin is with your engine. If you don't hear the noise check the flexplate for cracking & then transmission. Start hear and get back to me.
