How do I know which variant fits my 2018 GMC Sierra 1500?

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 2018 GMC Sierra 1500?

The attributes that differ between variants are: Average R&R, Bell Housing, Fluid Included, Fluid Type, Pan Bolts, Pressure Control Switch, Pressure Switch In Case, Shift Type, Tail Housing, Throttle Cable, Transmission Family, Transmission Speeds, Yoke Style.

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.
