Just courious, has anyone tried to cost start a MT Gladiator?

I have not. It would be difficult with the auto transmission, since it won't go out of park unless the engine is running. There may be an override to release it, but with everything computerized, it's no easy task.

MT = manual transmission

MT = manual transmission

That's why I specified automatic in my response. The MT has the same potential issues with everything computerized.

The AT will come out of park but it will auto-park if there's no weight in the driver seat because of that whole Grand Cherokee killing Chekov incident. You can't push start a typical AT because the input shaft drives the fluid pump and a transmission in "Park" is actually a transmission in neutral with a parking pawl engaged. Pulling the transmission out of park will disengage the pawl so you can roll it but you'll never generate the fluid pressures necessary to get the transmission to shift from neutral to a forward gear.

If you can't push start the MT, that's a massive oversight on Jeep's part because the redundancy of being able to bump start a dead truck is largely why I prefer them for trails. I have never seen an MT that could not be bump started.

I agree it's one of the reasons I prefer an MT and it is a feature that has come in handy many times over the years. I'll have to give it a try later today.

If you put the truck in run with 2 button pushes of the engine start, throw the manual in first and push, it should start. The only thing, that i feel like may be a problem, is that the stop start feature on our jeeps may hinder it.

That's the standard method, turn the key to run, put the trans in 1st or 2nd depending on gearing, push or cost down a hill, pop the clutch and go.

I'll see if it works the same with push button start after work. Couriosaty may get the better of me and I leave the house at lunch to test this.

 

[LostWoods]

Do not try to bump start these trucks in first. Holy hell that would be hard on the drivetrain with that 5.13 first gear. Get them rolling in neutral then clutch in, go for 2nd, and slip it out with a little gas until it kicks and you should be good to go. Just be smooth with it.

 

[Nick]

I couldn't break away for lunch. Once I finish up what I'm doing for work I'll give it a shot.

The other reason you can't roll start an auto is the clutch packs need pressure from the pump to lock up, you are not rolling an auto fast enough to induce flow.

Push to start won't activate the starter without the brake switch engaged. It will energize the ignition.

On my JKUR you do not need clutch disengagement to activate the starter relay, I'd be interested to know if they carried that forward

 

[Nick]

Yes you can bump start these MT trucks. #LostWoods is correct you don't want to be going more then a couple mph to do it in 1st gear, like as soon as you start rolling. 2nd is much more forgiving and 3rd takes at least a 5 mph roll. I used about a 25° hill for coasting to test.

Though I wonder, if your (edit) battery is BATTERIES ARE really, really dead, can you even put it into run with the pushbutton!?

I wonder if the "push the button with the FOB" method would make a difference in that case?

The fact that we actually do have two batteries might make that a mute point. What are the odds both batteries are ever stone cold dead?

 

[ACAD_Cowboy]

If the battery is flat dead as it is, you can't energize the ignition and the alternator won't make power until it's spun enough.

Assuming you have some power, the push to start should still function since you're not trying to crank, just turn on some relays.

And here we see why Toyota is smarter than Jeep and uses a standard freaking key with the 6MT Tacoma. This is a pretty substantial perk of a manual when out in the boonies and it's not hard to have too low a battery with lights and other electronics left on accidentally.
