Cool. Can't thank ya enough Bill. Like I said, friday i should have time to tinker with it some. I will post back what I find.

And it seems fine at idle, while standing still. Its while in 4th gear that things start to seem really "off". Cruising at 52 MPH I found the rpms "hunt" some. They will shoot way up, then calm down, and bounce around a little. The converter will start locking and unlocking at slightly higher speeds. Also, converter will NOT stay locked. No matter what speed (took her up to 80 on the way home the other day to be sure) , if I remove my foot from the gas, the converter automatically unlocks.

If I turn OD off, truck drives almost completely fine. The issues are not any where near as pronounced.
