Hi there,

If the water was high enough to enter the engine, you may have ingested water into the combustion chambers, As water is noncompressible you may have suffered some internal damage (the knocking noise is a concern) Have all the oil's chanced as water in the transmission will be very detrimental. Have brake systems checked It is not just the water that causes problems but the large amount of silt that can be deposited as well. Advise your mechanic as to what happened and he/she should know what to do.
