I recently destroyed the torque converter in my V8 swap thinking it was a weak unit. I removed it today and found out there was no oil inside. Being not an expert of 4l60, Could someone tell what can cause the oil not to go from the tranny to the TC? (Solenoid? Sealing?...) to know what to look at and what to order. BTW, I tried TO turn the stators inside the TC, and there is no résistance at all, I think it is completely dead (Is it the correct way TO check the TC)thanks.
