    A front pump seal replacement requires that the transmission be removed from the vehicle.

    To replace the seal:

    • Place a drain pan under the torque converter and remove it from the transmission.

    • If you quickly rotate it so the transmission end faces up, very little fluid will leak out.
    • Remove the old seal with a chisel, hook puller, or slide hammer seal puller (Figure a).
    • Install the seal on the installer and drive the seal into the pump. (Figure b).
