'94 Chevy Truck: 8.9 et, 408 twins
I have a 30k gvw cooler with a 10 inch fan mounted to it.
I just went out and commanded lockup and it seemed to work for a bit and then unlock. The TCC slip would range from 200 to 700 at times. but mainly its about 200. I dont know much about the TCC duty or any of that other mumbo jumbo, but if anyone does I can tell you what the numbers are. If I hold the gas steady, it will stay locked up fine unless I go up a hill. If I put it on cruise it locks in and out.
