The shifter transmission bracket is designed for the K20A/A2/A3/Z1 transmissions. This shifter cable bracket bolts directly to the top of the gearbox case and is responsible for securing the shifter cables. Some used transmissions are sold without this part which is required for the shifter cables or simply replace your old, rusted bracket with this fresh new OEM Honda part. We recommend using this bracket over aftermarket options because of the Honda's geometry and strength.
