As for the math on the trans:

Right now, with .71 OD in fifth gear my RPM at 75 MPH is 2190.
If I did the conversion (at about $2000 even doing everything myself) I would have a .61 sixth gear and would drop cruising RPM to 1878.

Might make sense with 4.10 rear gears, but makes no sense with the 3.73.

I have no trouble getting underway with the 3.10 first gear.

Happy with it just the way it is.

Serviced the trans yesterday using TranSynd. Wish there were a way to tell for certain what fluid was in it. Had a really crappy aftermarket spin-on filter on it, but I don't THINK the pan had ever been off. Just to make certain I get as much of the old fluid out as possible (without using a very expensive pump set up) will drive it a few days, then do a drain and fill one more time.

Man, the underside of this truck is clean.

Also, it drives great with the new Bridgestone V-Steel tires. Gary made me a helluva deal on those, and I am very thankful.
