That correct Jake. That is the info shown on that screen. Just went for a test run & changed the values from anywhere from 30 mph to 150 mph. I could get the lockup to activate at 40 mph but it would disengage after about 10 or 15 seconds. I was able to repeat this result 3 time & that was it. I also tried in performance mode to see it that would change anything but it did not. Finally I set it up for WOT & the TCC does activate but only when hitting WOT from about 60 mph . From a standing start at WOT the TCC does not engage but again I dont know if it should. I also checked the TCC solenoid for resistance & I was showing 14.5 ohms . Finally I checked the oil level & it was low by about 1 quart. I will be talking to the guy who rebuilt the trans to see what he thinks. G.L.
