727 kick down

[x6xdemonx6x]

What activates this the only to get my jeep to kick down is to shift it manually...i do know there is a hard line from the tranny (might be the tcase i can't remember now) that has been cut and had a section of vac hose slipped onto it buts connected to nothing. Aside from that and it only idleing at 500rpm on start up when its really cold it runs and drives fine and the 4wd works great. Got a holly 2 barrel carb on it want to say its a 2300 but not positive it is manual choke if that helps. Its a 91 waggy

Go to this site------http://oljeep.com/edge_parts_man.html

Check out the TSM for the '82 model, also the parts book.
This will show you the information you need.

[x6xdemonx6x]

will give it a look. Does it matter that mine is a 91 model i forgot to mention that yet again lol

727 doens't have a kick down. It is a 'trottle valve' lever.

Adjustment is important.

Also, someone has been doing some mods to your engine. A 91 would not have a manual choke.

pulled fully forward at full throttle.

If someone has been screwin with your engine. They may have disconnected that throttle linkage. If it's missing parts, you can get a Lokar kickdown cable kit. When we got my brother's Cordoba, the redneck bum who was PO had wired the secondary linkage so it would open all 4 barrels at once. When he did that, he also yanked the throttle linkage and tossed it in the trunk. So, he cooked the tranny. If you're missing parts, unless you can find a donor, it may be easier to get the Lokar or other aftermarket kit and use the cable linkage.

thanks for this pic from a glance it looks like i am just missing part number 6 and the fastener i'll have to crawl under it and make sure the rest is there also though.

wonder if i could wire something up to get it by for now the tranny and tcase have been gone through and rebuilt so the last thing i want is to burn up the tranny.

For a TEMPORARY fix, you can move the throttle pressure arm till you feel an increase in resistance. That is the KICKDOWN stage. Back off just a small amount and tie it down till you can find the linkage. The 727 line pressure is adjusted by this valve and if left at the 'end' you risk smoking the clutches and possibly a band in a hurry since at rest, the line pressure is much lower than at teh mid point.

Keeping the throttle pressure at the midway will cause the shifts to be held longer so you may have to adjust it a few times to get it right.

A coathanger might work in a pinch if you could bend the trombone slider part (#15) to work right.

[x6xdemonx6x]

ah i was assuming 15 was the throttle cable part so i am missing that part to I was thinking a section of hanger through the arm into the linkage on the carb.

[Tatsadasayago]

You can use the carb side linkage from many 70s era dodge cars, trucks and vans that came with the 727. The only real differences between linakes is whether the engine is big or small block and 727/904. For the 360 AMC I would go with the 318/360 trombone and rod. Be sure to grab all the spring washers, return springs, hardware and clips you can scrounge!
This is an alternative choice should you not be able to locate a 727 FSJ at your local salvage yard.


Good Luck!

Nice drawing Hunter!

The kickdown point is at the right end of the 'Trombone' so some sort of stop needs to be fashioned.
A 1/4"-20 nut/bolt and large diameter washers would provide an adjustable stop in this case.

[Murphy]

Thanks. The bottom carb throttle post just pulls on the trombone, but you're right, there will have to be some kind of flat piece that keeps it next to the carb throttle but still lets it slide. There should be a groove for an E-clip or small hole for a cotter pin to hold a washer on the bottom throttle post. If there isn't then maybe a tiny bolt and an oversize washer with little jamb nuts or something. You don't really need the adjustable stop if you bend it to the right length. Just re-bend if it is too short or long.

[x6xdemonx6x]

got it warming up to go test drive it now and see if my idea works...interesting little tid bit i decided to connect up my cruise since its there and i wanted to see if it would work after doing so the jeep wouldn't stay runing and ideled like crap then back fired up through the carb apparently i did get it set right lol. some how managed to keep my eyebrows

[x6xdemonx6x]

alright with a coat hanger rod i got it adjusted enough to atleast kickdown and it seems to shift fine still...another interesting side effect my jeep runs cooler according to the indash gauge according to my after market gauge its about the same...i was thinking with it somewhat shifting the right waywont that increase my mileage also cause before this thing was sucking down gas like there was no tommarrow (i know they all do that but this one was bad)

[x6xdemonx6x]

more or less what i did only a little simpler. Went from the linkage to the carb with a str8 piece of hanger. Moved the linkage till i felt the resitance backed it off a har and cut to fit. Works good till i accidently dislodged it while romping around.

I had issues with my kickdown at one point. It also controls the 2nd to 3rd shift. I doubt it will make a big difference with mileage, there are so many other things that contribute to that. These rigs are rolling bricks.

[x6xdemonx6x]

what was thinking as far as mileage goes is that if the tranny isn't kicking down then its forced to work harder to get up to speed and maintain it (to a extent) causeing it to burn more fuel...but i could be wroung was just a thought.

[Murphy]

Oh you're right, it should help, at least a little.

[x6xdemonx6x]

i've got a 88 chrysler with 318 and i think a 727 tranny i was going to pirate the linkage from but it would appear that its quite a bit different

[Murphy]

If you don't have a junk yard close to you that has the right one, then it shouldn't take long or cost more than a few bucks from someone parting one out. Keep your eye on the For Sale forum, you'll get her fixed up before long.
