How do I know which variant fits my 2021 GMC Yukon XL?

Check the tag on your unit before ordering. Please verify the tag on your unit before ordering. A VIN shows the part your vehicle was built with, but if it has been replaced, the tag on the unit in your vehicle may be different, and the tag on your unit is what determines fitment.

What tells the transmission variants apart for a 2021 GMC Yukon XL?

The listed attributes are the same across variants, so the tag on your unit and the interchange tag IDs are how you tell them apart.

Fitment data from the ETE catalog, our own completed orders, and Hollander interchange data. Numbering systems are listed separately and never merged. When a record lists more than one variant, the tag on your unit is the final word on fitment.
