check motor mounts
If it happens intermittently, it is caused by a broken tooth or teeth on the engine ring gear. Thus when the starter solenoid throws the pinion gear backwards, the pinion and ring gear will not engage. In some rare cases the pinion gear can come off or the solenoid itself fails, yeilding the same result. You can test this by putting the car into gear and moving it slightly to move the ring gear (in some cars). Sometimes opening the drivers door and jumping up and down on the door sill can rock the engine enough to move the ring (again in some cars). The car might start. The only fix for this ultimately is to replace the ring gear.
different parts inside the gearbox will have driped dry and make more noise after starting from cold this noise should go away fairly quickly as the running gears move the oil around the gear box
That would be your transmission. It may be slipping, or you may be lossing a gear. Have it checked.
It will move for you, in fact the higher the gear the easier it will be to move. When you push the bike and begin to rotate the rear wheel with the trans in gear you are rotating the crankshaft of the engine, jumpstarting the engine for all intensive purposes.
Symptoms of a bad converter vary. The vehicle may not move at all when in gear. The vehicle may exhibit engine stall when put into gear or may not have power during takeoff. Also shudder may occur when under load. Noise in the transmission when put into gear forward or reverse.
Check to make sure that the fluid is full. With a helper and the vehicle sitting still in park, move the steering wheel fully side to side while one of you listens at the wheels to find the noise.
slipping clutch? get a new one
There's a few reasons: When a automatic transmission vehicle is turned on, the small but the seemingly small burst of energy it takes to start the car by means of combustion, it may rock the motor mounts and cause maybe a moving.. or bumping sorta sound. When you move the gear lever in any position, the energy from where in neutral, the torque converter, which keeps the engine running while in a gear, or switching to another selection of gears, has to mesh with the flywheel of the engine so that you can press down on the accelerator pedal/ brakes and causes the noise of the motor mounts absorbing that energy. However, the noise shouldn't be a very loud noise, if it seems loud it could be either a motor mount(s) going bad and needing replaced, to possible transmission problems.
Nothing funny here....bad clutch disc.
Assuming the vehicle doesn't move when you put it in gear, it sounds like the clutch is blown.
The lubricant in your joints creates bubbles our of gases. When you joints move the bubbles pops. That is the noise you hear. Also, something the tendons are a little ruff and make noise as you move the joint.
1) reduce throttle to idle speed 2) move gear shifter to Neutral position 3) move gear shifter to Reverse position.
