Drivetrain 101

This kit is designed to be incredibly easy to install, and yield maximum improvement to the problematic AS69RC with innovative and exciting product solutions to real world problems. We’re thankful that you chose this product, and hope to be your first recommendation for all performance drivetrain needs.

As many know, the problematic 10R140 transmission is lacking in mechanical and hydraulic quality. This transmission was never meant to be a "premium" option, but rather a high volume, economical option that favors EPA regulation. Fortunately, Next Gen has been adamant about bridging the gap between this naturally inferior transmission, and it's potential for tremendous success and reliability.

In this Drivetrain 101, we thoroughly inspect and analyze the origin, strengths, weaknesses and pragmatic upgrades of the 48RE transmission. Further, we point out notable differences between the two, and answer other frequently asked questions!

From Escalades to Corvettes, the 8L90 transmission has been employed across a cornucopia of General Motors vehicles. As leading experts in the 8L90 transmission community, we are proud to bring you an installment on this unit in our popular Drivetrain 101 series.
