loud rattling noise when idling.
A automatic has a flex plate and a tork converter.. A manual trans has flex plate and fly wheel...
Yes
The flex plate connects to the crankshaft and bolts to the torque converter. The flex plate also has a ring gear that meshes with the starter. If the flex plate is in good condition it can be re-used. Check the gear to make sure that none of the teeth are worn. If all teeth are still in good shape and there are no cracks in the flex plate it can be reused. very commonly found in older ford f250
remove engine or transmission replace flex plate (flywheel).
Yes, a 168-tooth flex plate can work with a 700R4 transmission, provided that the engine it is mated to is compatible with that flex plate. The 700R4 typically requires a specific flex plate to match the engine's starter and flywheel specifications. Always ensure that the flex plate is designed for the engine and transmission combination you are using to ensure proper fit and function.
To my knowledge the only small block flex plate that doesn't interchange is the small block 400.
