1986Comanche

its pretty odd for a dealer to do ANYTHING if they didn't get paid for it. especially if it involves swapping a 5speed for a 4 speed with the same gearing? that's just a complete waste of time unless the one is exploded. :dunno: thats weird man. you said they also swapped motors at the same time? I'm not sure when they swapped motors. the truck was sold in mid-87 and I think it was a dealership vehicle when it was sold. maybe they beat on it and blew it up and swapped in what they had to sell it? the PO explicitly said he requested it built with an ax4 and v6 2wd. it came with 3.55 gears. lemme see if I can dig up all the info I have left... It probably has 3.54 gears since that is one of the ratios available in 1986 with the 2.8L V6 and 5 speed. I would say it was swapped out because the old transmission went bad and that's probably what they had laying around or they got it somewhere cheap, so they put it in just to sell it and most people wouldn't know about it, or know the difference really.

Yes, 1987s do have a fuel pump ballast resistor. I have a 1987 Comanche SporTruck 4x4 with the 4.0L I-6 sitting here right now and it has a fuel pump ballast resistor on the drivers side front inner fender.

Also there is no such thing as a Comanche Eliminator or a Comanche (S) in 1986. That VIN decoder is wrong. Those 6s do not mean anything by themselves. In other words each 6 does not mean something. They are together. 66 is the series of truck that it is. Every Comanche from 1986 to 1988 that is 2WD and has a longbed is a 66 series. Mine is a 66 series also because it is 2WD and it is a longbed of course. Every 1986 Comanche is a longbed. 65 series is the longbed 4WD Comanche, 63 series is the shortbed 4WD Comanche and 64 series is the shortbed 2WD Comanche.

Also, you might want to check out this Jeep VIN decoder. It is a lot better than the one you used. http://jeep.avtograd.ru/VIN/vin_en.asp

According to the 1986 Jeep Comanche Factory Workshop manual VIN decoder on page A-3 your VIN decodes as follows: 1 - United States J - Jeep Corporation T - Truck W - 2.8 Liter V6 W - 5 speed floor shift (2WD) 66 - 2WD Comanche 1 - Trim Package - Custom 0 - Check Digit G - 1986 T - Toledo, Ohio 022101 - Sequential Serial Number Evidently your Comanche came from the factory with a 2.8L V6 and a 5 speed transmission.

So, JeepcoMJ what is the VIN on this so called "factory" Comanche with a 2.8L V6 and a 4 speed? We want to verify this.

hey bud, I'm not sure really what your skills are or anything, or your history, but I can tell you, when I get a vehicle with a 4 speed manual transmission, I can tell. it was a factory 4 speed 2wd manual. now, I'm not sure if you understand something about jeep; any owner could basically order the jeep however they wanted, so long as the feature was a available feature. now, being that it's the same bellhousing, same transmission EXCEPT that the ax5 simply has a 5th gear and syncro (geonovast did a ax4 to ax5 swap using parts from my dad's old diesel transmission), they're easily interchangeable. the thing is, I'm the second (3rd since it was in my mom's name for 2 years) owner of the vehicle, and the original owner said he ordered it 2wd 2.8 4 speed because it never saw winter or highway use. he didn't need 5th gear so he didn't get it. just because it wasn't available in the brochure or on the showroom floor doesn't mean a build sheet couldn't be built for it. that's almost like saying that 1986 was the only year for a 4 cylinder 5 speed 4wd comanche (I've been told that's fact, when I owned a factory original 4 cyl 5 speed 1987 4wd comanche, and that trans is now in this 86). anyways, back to Pete's topic, yes I've seen 3 comanches with T4 or T5 transmissions, years 86 to 87, and 2 were 4 cylinders, the other was a v6. the v6 was a swap and the engine/tranny were from an 84 or 85 2.8 cherokee, so that doesn't count. I did not say they couldn't be swapped, of course they can be swapped they are basically the same transmission and that is the only way you'd have an AX-4 with a 2.8L V6. I would need a valid VIN before I will believe that it came from the factory with a 2.8L V6 and a 4 speed. That will verify it right there for a fact.

To the best of my knowledge the T-4 and T-5 were never used in the Comanche. They were only available in the 1984 Cherokee when they had a production shortage of the AX4 and AX-5. My 1986 Jeep Comanche factory workshop manual does not list the T-4 or T-5 as being used. They only list the AX-4 and AX-5. Also people keep insisting that the 2.8L V6 came with an AX-4 4 speed manual transmission and they did not. They were never available with a 4 speed and it was never an option. The 2.8L V6 either had an AX-5 5 speed manual or a 3 speed automatic. The 2.1L Turbo Diesel was only available with a 5 speed manual. sorry to call it...but that's not correct. my 1986 comanche was 2wd and ax4 originally. it had a 2.8 and had never had anything done to it except blow the transmission, and replace the blown 2.8 with a rebuilt 2.8. after the tranny blew, it sat in a field for years and years until I came up on it, with the tranny laying in pieces in the bed. oh, it had 60,000 original miles on it at that point as well. Nope. That's not possible. The Factory manual states the AX-4 was used with the 2.5L I-4 only. That's it. The Factory Showroom brochure also states the same under 4 speed manual floor shift it states NA V6 or Diesel. I am sure they know what they built. It probably was an AX-5.

I have heard the front springs on some kits are different per side. The drivers side spring might be a little taller to make up for the weight of a driver being in it. The springs should be marked, but a lot are not. The taller spring should be on the drivers side and if it's not the drivers side will lean. You might want to check the springs out and make sure this isn't your issue. Hope this info helps.

No Fuel Injected vehicle has a choke. A Choke is for a Carburetor.

You're allowed to have a flatbed in PA. It has to cover the tires. The tires cannot stick out past the sides of the bed. It has to have proper lighting. Taillights, turn signals, brake lights, backup lights, and license plate lights if your plate is mounted to the bed. Other than that you should be fine. You do not have to R-title your truck just to put a flatbed on it. It is completely legal.

Your Comanche is actually a 1986. They didn't make a 1985 Comanche. The first year of the Comanche is 1986. They did build some of them in 1985 for the 1986 model year.

Here's a place I found when searching online for carpet for the Comanche. They do sell carpet for the Comanche and just about any other vehicle too. I have never bought from them, but just ran across them when searching. They list the carpet as being for 1986-1992 Comanche Pickup and have many different colors to choose from. Hope this helps. http://www.autocarpetoriginals.com/jeepproducts.htm

Have you checked the fuses to make sure they're all good?

Well, I'm glad the info helped and that you got your problem worked out. That's why we're all here, to help other Comanche owners out.

With a digital multimeter and by loosening the screws on the TPS and turning it. The holes in the TPS are slotted so that it can be turned and adjusted. You need to have the voltage or OHM specs to adjust it properly, but I don't have them off hand.

When you replaced the calipers did you put the correct caliper on the correct side? I have seen this done before and they will bleed and everything seems fine, but the brakes never totally bleed correctly and the brakes are spongy. The bleeders are supposed to be at the top on the back of the calipers not on the bottom. If the bleeders are on the bottom you have the calipers on the wrong side. Also your front brake hoses could be bad not allowing you to bleed the brakes correctly. They go bad inside and come apart and restrict the flow and act almost like a one way valve allowing fluid to flow one way, but not the other. If the hoses are old and cracked I would replace them just for safety.

Comanches never came with ABS from the factory.

My guess is that you have the wrong bulb or bulbs in the left taillight. If you have a 1156 single filament bulb in the taillight where a 2057 double filament bulb is supposed to be it will do what you are describing. Are all your dash lights blinking with the turn signal too? What the single filament bulb does is connect both the contacts in the socket and when the turn signal blinks it feeds back through the electrical system which would explain why your front turn signals and the other taillight are blinking too. It is feeding back through the parking light side of the system causing all the lights to blink like the turn signals and they are all in one on the Comanche parking lights/turn signals thats why they are double filament bulbs Both top bulbs in the taillight are supposed to be a 2057 double filament bulb and the bottom bulb is supposed to be a 1156 single filament bulb for the reverse lights. Hope this info helps.

The 1986 Comanche doesn't have a ballast resistor. My 1986 with the 2.5L TBI doesn't have one either. They started using the ballast resistor in 1987. I don't know if the 1987 and up 2.5L has one or not. I know the 4.0L has a ballast resistor.

I just looked at my 1986 Comanche and the line comes out of the top port of the height sensing valve and goes to the T. Then a line goes from the T to the rear brake hose.

The Comanche taillights actually call for 2057 double filament bulbs. 2 on each side in the top of the light and 1156 single filament bulbs for the reverse lights 1 on each side in the bottom of the light.

That makes me want to get my Comanche bucket seats put in mine and test them out. I got them out of the 1986 parts truck I have that had factory buckets.

I thought so, but remember reading somewhere that it was 1984. Just checked, and you're right. 1984 was the first year of the Jeep Cherokee, but not the Comanche.
