While the Elk was running,I checked the transmission fluid level, it appeared to be a quart low, so I added 1. I then checked it while it was running, it appears to be overfull. I then pulled the hose off the back side of the thermostat, where the fluid is returning to the transmission. When I pulled it apart fluid came out. So apparently the cooler has fluid in it. So I'll have to get a pump and remove some of the transmission fluid.
