Manual Torque Converter Lockup

Man, I can't but think that is not a good idea. If the load is light let it lock up as it will reduce heat. But I understand what you are saying and I believe what you really need is gears. That will make it drive the way you want it to and not be shifting all the time.

I am running 3.55's and I plan to regear to 4.10 in the very near future. My camper only weights 3,600 lbs dry but I've also got a CJ7 crawler that I haul alot as well. With trailer it pushes the 5,000 lbs mark.
Any idea how my mileage will suffer when I go from 3.55's to 4.10's? I get around 15.5 mpg now.

I have 3:92's with 33" rubber (275/60/20) and I can tell you for one that the 3:92's aren't even enough for the 20" wheels. I regularly tow, actually is all i currently do with my truck and it does lag a bit off the line and up hills with weight.
and 15.5mpg with a 5.9L?? ohh, you got a 2wd.....yeah so, I would go for 4:56's for pulling power and happy medium of 4:10's for power and best MPG's. i think the 4:56's will run you slightly lower mpg's than the 4:10's with that trans/engine combo but i could be wrong???

I would get one of these:

and throw in a set of 4.56's. They wont hurt your mpg's, or at least they have not on mine, my mpgs went up after installing them. You also want that low end grunt that they'll give you. The 4.10's would be better than the 3.55's too but IMO the 4.56's are what you are going to want. The less strain on the engine the better the mpg's are going to be since it is not going to be working as hard. With that said I can only vouch for what my truck has done, I have know idea what it will do with yours.

yeah, with those 31" tires/wheels, i would say 4.10s would be the way to go. if you plan on going bigger in the future though, might as well get 4.56's. i have 4.56's and 33"s, and i just got 17.3 mpg hand calculated on a long trip. so as said by numerous other members, dont fear the gear. it wont hurt your mpg's, and it will make driving so much more fun.
