I have replaced my 6R80 auto with a TR56 magnum xl. At the time of the swap the car/tranny had 41k miles. No probs with tranny. I have everything but the oil cooler lines. Asking $1800 for everything. Figure the tranny is worth $1000 and all else is worth $800 (torque converter, support, pedals, wire harness, oil cooler, drive shaft). Shipping will be extra. Thanks.
