At high speeds (70 mph plus), I'm getting a weird humming noise/vibration coming from the Atlas 2 speed. I can feel it in both sticks and if I shift them slightly, the sound/vibration changes a little. The sound completely disappears when 4HI is engaged. Also, the rhythm is not in sync with the tires or driveshaft. It vibrates for about two seconds and then it goes quiet for one second then repeats…

I called Advance Adapters and they said to take it back to the shop that installed it and have them check the linkage. Just thought I would check here to see if anyone else has had this happen…

One more thing, my stock T/C exploded about a year ago while driving 80 mph…
