Set transmission selector to 3. Presto, no more OD. Same as pressing the button.

 

as simple as that? so if i'm doing 70 i can shift to "3" and it won't do a kind of "money shift"? i was always too scared to try at that speed. after 5 years and I'm still learning new stuff! thanks

 

You don't have to floor it. Just apply more throttle until it kicks down, and go. You'll get a feel for how much it takes.

Regarding what he said about overdrive:
Without a transmission, your axle would be powered directly by the engine. The higher your RPMs, the faster you go. If your engine slows down, you slow down. That would be a 1:1 ratio because they're directly linked. Instead, your transmission has multiple gears, and each one is a different ratio.

The lowest gear (1st) has the highest ratio. For the sake of easy numbers, let's say the transmission's input shaft (from the engine) spins 5x for every rotation of the output shaft (to the transfer case). That's a 5:1 ratio first gear.

It shifts to second, and now it's a 3:1 ratio. This let's it keep spinning the tires at the same speed, but you see your RPMs drop to match the new ratio. Now as your RPMs climb, you go faster than before because of the different ratio.

It shifts up to third gear, and now the input shaft is spinning at a 1.5:1 ratio, relative to the transmission's output shaft. Now you're still accelerating, but your engine RPMs dropped again because the ratio changed.

You hit fourth gear, and now the ratio is 0.8:1 and the output is actually spinning *faster* than the input. That's overdrive.

Those numbers are totally made up for simplicity.

 

I don't know what "money shift" is, but 3rd gear will be fine for any highway speed. Conversly, if your TV cable is properly adjusted, you'll only need to push the throttle down about half way to get it to kick out of overdrive into passing gear. But either way works fine.

 

3rd gear is 1:1 in AW4s, for reference.

"Money shift"? It will jump RPM as the vehicle's momentum forces the engine to turn faster... is that what you mean? It's just like downshifting on a manual.

 

I assumed he meant a very expensive shift, as in one that would cause damage

 

Yeah, I thought maybe that too, but didn't want to take it for granted if he meant something else.

 

Yeah just watch out for that 1-2 setting...dumbest idea ever. I only allows 1rst or 2nd and the transmissions reasoning is psychotic(on mine anyways). 3 allows gears 1 through 3. I like on my ZJ that the shifter goes D->2->1 and there's a button to disable 4th that way you can "force" what gear you actually want. Also keep in mind the faster you press the gas peddle the more likely the transmission is to downshift too. That's part of the kickdown cable function as well. If it gets pressed quickly I think it opens valving(similar principle to a shock absorber press it hard and it puts up more resistance, opening the valve, press it slow and it'll easily extend) and also depending upon throttle position.

Edit: senior members please correct me if I have anything backwards/wrong. Haven't researched this stuff recently and I there's not enough coffee/monster in the world to keep me functioning fully while I'm travelling for work.

 

im in charleston SC, 29405 to be precise. Id love to take it off your hands but the might unicorn isnt going far from home until I get the thing looked over (suspension and suspected diff leak)

In all honesty, I thought about doing a milage change to make the one local match, but I just dont trust junkyard cars. My jeep mileage is "exempt" anyway, but I kinda want her to ear that million miles honestly lol.

 

thank you for the detailed reply, helps a lot. i do understand how a transmission works, but the overdrive part is what confused me.

i guess it's a term more used with manual transmissions, but yeah it's like if you try to shift into 3rd but go in first instead, basically grenading your engine/transmission. i think the 1-2 setting is somewhat idiot proof and doesn't shift in 1st if you're going too fast, but i never actually wanted to try for myself with the "3". i'll adjust my cable tonight and see if it makes a difference at highway speeds because right now i might have 1/3 of the pedal pushed in at 70mph, and when i press it all the way to the floor it takes a second or two before anything happens (especially if i'm on an incline)

 

alright, back home i pop the hood and the button that you need to press in order to adjust the tv cable is stuck there, it won't budge. does pb blaster help with plastic too? not sure if i should force more than i did, would hate to break it

 

Had that same problem on my dad's. I let is soak in PB for weeks and still wouldn't budge with all my weight and a screw driver to center my efforts. Was afraid of breaking it.

Remove the cables from the throttle body and removed the assembly. Underneath is a piece of that button where you can get a bite with some needle nose or small pliers. Looks like the rust swells in the plastic and freezes the moving metal part. Use your lube and go slow. Might have to use alternating pliers and button pressure from above but it'll break free. Be patient.

 

while you were posting i was checking exactly this and i noticed the metal clip under it which is indeed pretty rusty. so just so i get this right, do i need to remove this metal piece and put it back on or it can't be removed, just break it free from the rust with the pliers?

 

It's connected to the top button (sorry for lack of proper termage) and will pull the button down when you pull the tab down

 

alright i get it now. thanks a lot!
