Hi Stella,
Check your owners manual. It will depend on what type of transmission you have!

Dear Stella,
The best place to find this information is in your owner's manual. It looks like it calls for 75W-90 gear oil. You can use regular or synthetic.
You need to use what the manufacturer recommends so that you don't cause damage to the parts.
