But with the problem I have everything goes away when put back to stock. Bill has advised me not to reflash. Your symptoms will have to be addressed by Bill I think. Yes my hex is a TEJ one but yours looks like a newer version, mine looks more 1st gen for the 06 year.

Btw what gears and what size tires?

Hey, it has 3.73 gears and 33" tires. I plan to take another short drive tonight to see if it is still the same, would it make any sense to unhook the battery to reset the computer? Also, I reviewed the recommended interval for trans fluid change and there is a huge difference between severe duty, every 30K, versus regular duty which is 150K. That seems like quite a difference. Thanks
