Got a leak at the transmission on your Buick Regal?
This National left transmission output shaft seal is the genuine fix you need.
It's specifically made for the 2014, 2015, 2016, and 2017 Buick Regal models equipped with the 6T70 automatic transmission – left side only, so make sure that's where your leak is!
National is a trusted brand for seals and bearings, so this isn't some cheap knock-off.
It comes with original packaging and any necessary hardware for a proper install.
A leaking output shaft seal can lead to low transmission fluid, which is bad news for your transmission's health.
Replacing it is a smart move to protect that expensive drivetrain.
This is a direct replacement part, meaning it's designed to fit perfectly in place of your old, worn-out seal.
Before you order, definitely use the Amazon 'Confirmed Fit' feature or double-check your vehicle's year and trim to be 100% sure.
A proper seal install will keep the fluid in and the dirt out, ensuring your Regal's transmission shifts smoothly for miles to come.
A great part for DIYers or professional shops tackling common GM transmission maintenance.
