Just got my DTT VB & TC installed and all I can say is WOW!!! My hats off to Stephan and Bill, they know what they are doing. My tuck pulls like 18wheller and hauls a**. I had a 95 CTD and it had a Dunright TC and Shift Kit and It was OK, But no comparison to this set up. There is no limit to what this truck can do now. I do have one question what transmission fluid do the majority of yall run?? They put dexton 3 in it. And most people say they use ATF +3 or +4. So what is the norm?
