This part facilitates the set up of a 4L80E automated transmission into autos manufactured by Common Motors that utilized the “G-body” platform. It’s a structural piece that bridges the automobile’s body rails, offering assist and mounting factors particularly designed for this heavier and bigger transmission. Its function is to make sure correct driveline angles and safe attachment, stopping extreme stress on the transmission and surrounding parts.
The need of this half arises when upgrading from a factory-equipped transmission (comparable to a TH200, TH350, or 200-4R) to the extra strong and electronically managed 4L80E. This swap is usually undertaken to enhance efficiency, enhance sturdiness for high-horsepower functions, or acquire the advantages of overdrive. The unique crossmember isn’t suitable with the 4L80E on account of measurement and mounting variations. Appropriate set up presents elevated power and longevity to the general driveline, significantly in efficiency or racing functions. Early options usually concerned fabrication, however aftermarket availability supplies engineered options for exact fitment.
