BMR's TCC007 transmission conversion crossmember lets 1998–2002 LS1-equipped F-Body cars accept a 4L60E transmission with proper mounting. The fabricated crossmember replaces the stamped OEM unit with 1.25-inch DOM tubing and CNC-formed plate to eliminate flex and simplify swaps. Intended for street, drag, and handling setups, it improves repeatability and drivetrain support while maintaining a bolt-in installation.
