I wonder if it does it in 4WD?

We're back from Sedona. Here's what I learned:

If I start my truck moving with the shifter in 2nd gear, that's the gear it stays in - period! No 1st gear at all.

I observed my torque converter lock up in 2nd, 3rd and 4th gears, depending on the load and speed. Once in a while, it would shift from 3rd with the torque converter locked directly to 4th without unlocking the torque converter and that would feel "harsh". With the speed control on, coming down a hill, as long as the torque converter stayed locked, I could feel engine braking, but if I tapped the brake to disengage the cruise control, the torque converter would also unlock and the feel of engine braking would disappear.

The TC would lock in 4WD, which I used on a few "unmaintained" roads for improved traction and control. But, now I have a VERY dirty truck!
