The BST 600 NAG1 Transmission is an OEM upgrade. When moving up to a 426 HEMI or adding a Supercharger this is the transmission you need. Replacing the weak factory clutch packs gives this transmission the ability to hold up to 600RWHP. Shifting is noticable when you need the power but yet retains a factory feel when cruising.
All of our transmissions are backed by a 1yr warranty when purchased with a new torque converter.
NOTE: A Core Charge is applied when added to the cart. The listed charges are refundable if cores are sent back with in 30 days of receiving your shipment.
