Thanks, I don't have 1-2 shudder. My shudder is when the TCC disengages during WOT, it doesn't shudder anymore though because I killed the converter though lockup still engages and dissengages. But I know exactly what is wrong with the transmission, I specialize in building these torque flites for performance and heavy duty use. But I used a cheap converter which I knew wasn't the best decision but like I said I only had so much money left.

The broken converter explains why the vehicle doesn't always engine brake and why the vehicle rolls down some hills. Thing is the converter didn't start to whine until recently, but during the time it wasn't whining when the vehicle didn't want to engine brake, I knew that it would be the converter. But anyways, my WOT 1-2 shifts are slightly delayed but that isn't a biggy.

I'm 1 mile from 133K miles!
