This is a 700R4 transmission bare K case only. No internal parts. Usually used for 4X4 vehicles. It uses the heavy duty aluminum torque converter cover. I have a couple of K case complete 700R4 cores also and one more regular case complete core. I also have alot of GM differentials and transmissions and some transfer cases for sale.
