Obvious Improvement in Transmission Performance

By Weave, a  Verified Buyer from Anderson, SC on  February 27, 2025
Recently took possession of a 2019 GMC Sierra 1500 w/10-speed automatic transmission. Definitely noticed some transmission slipping and hard shifts from time to time. Have read all about the problems people have been having with this transmission. Changed the transmission fluid out for the Amsoil Signature Series ATF and immediately noticed a smoother, more consistent transmission performance. Would definitely recommend anyone with the GMC 10-speed transmission make this change!
