Hi,

Yes, it is set up specifically for your vehicle. If you don't use the original one, it will cause likely cause drivability issues.

Additionally. make sure the gear ratio is the same in both transmissions. I believe the part numbers you provided indicate different ratios. You will likely need to contact a dealer for that information. It isn't something I have in a manual.

Let me know.
