Transfer Case in 2WD
2003 4x2, 2.3, 5 speed manual: I have enjoyed this little truck as a daily driver since it was new. If it had low range it would be a lot more useful. Any ideas on an economical trans case installation? I don't want a 4x4 conversion just the low range. By the way: MPG recently went up about 10%. Strange this happened at 45k miles. Same gasoline (Reg 87), tires, tire pressure, motor oil and driving habbits. This little darling now gets 30.5 MPG in mixed driving and I don't baby it. I drive it up and down mountains every day.

The tranny wouldn't matter, there's not much difference if any in the gearing of a 4x4 tranny and a 2wd tranny. If you also installed the t-case, then you would have 2wd low range. Then you would be adding more weight and drag that would effect your mpg. I would just install a set of 4:56 gears in the rear diff and call it a day. You could buy a lot of gas for the price of an under drive unit and the 4:56's wouldn't use much more gas if any than adding a 4x4 t-case and tranny with it's extra weight and drag. My 4x4 with the 4.0 and 4:10 gears gets 22 mpg local and 24-25 highway, I'ld do the gear swap, it's relitivley cheap and much more practicle.

---------------------------------------------------------------------------------
the only extra weight would the t-case( maybe 75/80lbs). theres no xtra drag when its in 2wd.. that 2.3 would be SCREEEEMIN with 4:56 in it.

in 2wd in a 4x4 t-case is a straight shot through. you arent turning any extra shafts,chains,gears. after 97 when the TTB stoped and the IFS took over then when its in 2wd you still turning the front axels(no hubs) the diff and so on. now he gas milage go down

The t-case it's self is an extra shaft, trust me, it does add extra weight and drag -vs- the t-case not being there at all. At anyrate, it's still a little extreme just for lower gearing, might as well just convert it over to a 4x4 at that point and really make it worth your wild. Get a front diff and d shaft and have a 4x4 if your going to that much trouble. I'm not saying the t-case adds alot of weight or drag, but when you have only a 145 hp engine it doesn't help the cause like a set of gears would. The 4:56's would be added performance in all gears with no extra weight. Adding gears makes the most sense in expense and hassle.

The low range will give him lower gearing, it's the same principle without the t-case and hassle and expense of installing one in a vehicle that doesn't have one or set up to have one. The new trucks have electric shift motors, so he'll need all of that unless he uses the old manual t-case, then he'll have to cut a hole in the floor for the shifter, he needs a different cross brace and the 4x4 tranny. A gear swap will give hime the desired effect without the expense or hassle. However, if he wants the added weight, expense and hassle, it's a free country, go for it.
