    As far as the overdrive goes, good info for sure. The D20 overdrive unit's big problem is that it can't handle much power (really torque is the issue), and the reverse/park function has to be manually pulled if you don't want it to roll away At least I think that's how it needs to happen at this point. They're interesting units...trouble with them is that reverse/park function. But seeing as you have the 401 I'd personally just as soon put in an overdrive tranny out of an XJ or ZJ; can pick up a whole salvage one of those for like $400 and get a good tranny out of the deal. Trouble for me is those don't bolt up to ETIHER the B350 or the D20...of course the flip side to THAT is that even from the factory they put adapters on either side of the tranny Anyway you get my .02 now.

    Speedo was corrected and very accurate. 33 MT/Rs btw.

    401 ran and sounded great, but used gas. Sigh ...

    The Gas Pig is what I called it.

    PITA as it is super hard to get the dam thing to take fuel.. which is required ALL too regularly !!

    I won't mention how I fixed this . . .

    Be cautious with adding an OD unit. Your drivability may suffer greatly.
    Gearing is important for balance drivetrain performance.
    Will load the trans more, which can result in heating the fluid.
    Heat is the enemy of trans longevity.

    Just some food for thought here, not going to push you one way or the other on the tires, but I used to be an all-terrain LT all of the way. Then when I got the '71, it had the P225/75R15 Hankook Optimo H724 whitewalls on it. Those are the equivalents of the Kinergy H735s now, and came in 235/75r15, too. I kind of figured that they'd suck in the snow and everything. Then last winter, B350 freshly put back together, I started driving it with them, and I was REALLY impressed. Since you're from ND you know what the snow's like around here; anywhere the body didn't hit I didn't have a problem going. Only time I got stuck (and trust me, I went through some unplowed lots that were drifted to 2.5' deep with 3' deep entrances) was when I slammed on the brakes on the icy backroad for a deer, and put it in the very steep ditch backwards. The snow there was up to the bottom door crease. They seem to do fine in the sand, and I haven't had any trouble with the little bit of mud they've been through. 1800 something pound per tire load rating, I believe, so on these more than enough for any towing you <should> be doing with these. So I've been super happy with these, and with the non-power brakes, I can modulate them REALLY well on the ice They do also offer a nice soft ride, look good, and are more aerodynamic thus get you better mileage

    Oh I forgot to mention I got all of those places without even airing them down These things are stupid capable. I love it

    Good information for thought, and that is what I was hoping to get, are the experience from those that have tried them....good or bad!

    Thanks and would like to hear more

    I put a GV in my Dodge Ram back in 2003-2004. I've had to replace it 3 times due to reverse going out. I probably would have changed it a 4th time but pretty much stopped driving the truck about 5 years ago. Lol. The GV uses clutches for reverse and the oil capacity is something like 1.1 quarts so changing the fluid when you're suppose to is critical. I'd rather change the transmission and tcase than put a GV on.

    Yep....as my rig I want to build mostly for road use pulling our camper and light trail use.

    I want tread that will get more comfort miles traveling from home and back, but with a little off road grip, than airing up & down for serious off road traction.

    The LT are moderate grip, and higher plies for load.

    I have a CJ5 for the crazy off road stuff

    I like the LT tire route. I am not going to lift mine for now and will probably go with AT tires.

    Not feeding anyone for free, as there are ways to pay for stuff now, as long as you have a cell signal.

    Thinking more just enough to limp back to the pump, so nobody is stranded

    Not going with the "big" tires, as they serve me no purpose, so the 31's IF I do go with them, would be as big as they would get.

    Thinking more of stock all season LT tires, so keeping the torque values on the tires, and not on horsepower.

    Carb is the nice word

    And not a fuel pump for engine use, just to transfer from reserve to main tank.

    Same as a pickup with a service tank in the bed.

    Say I have 20 useable gallons OEM tank, and 30 in reserve tank.....if I average a road trip @ 14 mpg....thats 700 mile range.

    Light trail off road use, the reserve can be set up to put gas in my own rig, or into other rigs with an external hose.

    Must be the farmer/rancher upbringing coming through me again
    Cussing? AGAIN? When was the first time?

    You're willing to fill up other rigs? If you're not making them pay more for it than you did (I mean, they're the ones who ran out of gas in the middle of nowhere), you are nicer than I am. Unless it's your own rig

    Overdrive - bolt on

    Thought is for general information as I had the thought to find one for my rig.

    Overdrive unit available (for hiway OD only-which is what I want) bolts on back of the existing TC, requires a new rear only drive shaft, and turns the 727 3-speed into a 6-speed.

    The bolt on unit electronically shifts in manual or auto shift mode with 1/2 gear increments, to the full gear shift of the auto trans.

    So your 3-speed will shift like this
    1 to 1-1/2 to 2 to 2-1/2 to 3 to 3-1/2

    Looks like the bolt on unit is right at $3200, then need shorter rear drive shaft, as unit is about 12" thick.

    Best part about it, they have an exchange program so when you change vehicles, you get credit for exchange to different unit.

    Units handle up to 1200 hp, then need hydraulic modification up to 2000 hp.

    Looks promising....just need to find those money tree seeds and get that sucker growing

    Honestly....would rather spend this kind of money for an O/D unit, rather than FI.

    I would think that would work. I haven't really dealt with duals before though; when the '88 got an S10 tank in the back, it all-out replaced the stock tank, so I don't know about tying them together or anything.

    You know, if you went with fuel injection of some sort, you could run electric pumps in BOTH tanks

    A thought on fuel range in my FSJ



    I read a lot about folks trying to get more range out of their FSJ's, by adding the "K-5 Blazer" 31 gl fuel tank between the frame, where the spare tire was designed to ride.



    As it looks we need to run a second fill spout, and then to plumb the lines so it can draw from both tanks.



    Idea.......



    Add the second tank, instead of drawing directly out of that tank to run, what if I simply install an electric transfer pump in that second tank? And a fuel gauge of course!



    When my primary tank gets low, I could hit the switch and transfer gas into my OEM tank?

    Exactly! I don't mind some upgrades, and if the electronics are legit better then sobeit, but I'm NOT okay with driving an entertainment system on wheels. That's why I'm not big on most cars post-00s era.
