Hi welcome to will answer your question the best I can,

Here is a repair sheet for your mechanic so he can sort out this issue.

For the P0449.

System Inspection
Canister Air-Filter Inspection
1.Disassemble the Canister Air-Filter and hose from their respective positions.
2.Check the Canister air-filter for contamination.Disconnect CCV connector.
3.Is Canister Air-Filter contaminated with dust?YES▶ Replace as necessary and go to "Verification of Vehicle Repair" procedure.NO▶ Go to "Canister Closing Valve(CCV) inspection" procedure.
Canister Closing Valve(CCV) inspection
1.Return vehicle to original condition.
2.Ignition "OFF".
3.Disconnect the hose connecting Canister Closing Valve(CCV) to canister.
4.Blow air to the canister side of the valve and verify air escapes to the air filter side.
5.Turn ignition on and jumper a wire to GND(back probe) at terminal 2 of the ECM connector(CCV valve should click).
6.Blow air into hose and verify air does not escape.
7.Repeat this procedure 4 or 5 times to ensure CCV reliability.
8.Is CCV working properly?
If hose was pinched or restricted:
1.Fueling would be difficult if not impossible.
2.Restriction or blockage could cause pressure to accumulate in tank triggering a P0451.
YES▶ Check for poor connection between ECM and component: backed out terminal, improper mating, broken locks or poor terminal to wire connection. Repair as necessary and go to "Verification of Vehicle Repair" procedure.NO▶ Replace CCV. If CCV was stuck closed, inspect all lines and canister for liquid fuel. Replace any contaminated components and blow out lines.Go to "Verification of Vehicle Repair" procedure.

Sorry, Just got home from work. I don't know what the CCV would have to do with the engine whining sound or the eradioc tranny....Since code PO425 is not associated with the Santa Fe, I'm thinkin PO 449 is not the right code either.....???

Take a drive down to your local autozone and get a free code read out then repost the codes here for me.
