Over the years, much ado has been made over the name Jeep having been derived from its military nomenclature, GP, for General Purpose. This can be disproved easily by noting that until mid1942, the Army designation for the truck was command reconnaissance, not general purpose (that would come later). No doubt the demise of the 1/2ton Dodge Jeep as standard equipment contributed to the use also. When Willys began using the term "Jeep" in advertising, MinneapolisMoline balked. In June 1942, the House Committee on Military Affairs substantiated MM's claim to the name, citing numerous references in newspapers and magazines dating back to before 1940.

The term "GP" meaning "general purpose" has been repeated so many times it's considered fact.

When Willy's received the contract, the goverments was concerned about their ability to produce sufficent quantities (who wouldn't be in the middle of a war) and Willy's was forced to hand over their blueprints to Ford, which was also given a contract to produce the 1/4 ton truck. The Ford version was knows as the GPW. Original Ford documents explain the origin as "G"=government contract, "P"=the designation for an 80 inch wheelbase, and "W"=Willy's design. Thus the term GP entered the nomenclature, but it did not mean "general purpose".

This mistake pervades even in encyclopedias:

I have an 84 Scrambler (CJ-8) with a factory T-176.

The data above shows that there were no manual trannies after 1983, maybe a typo?

[butch6924]

I know the original poster requested that all info be typed in and then linked for reference but there is just too much on this site and I wasn't sure what exactly would be best to post here.

http://www.film.queensu.ca/CJ3B/Index.html

There's a ton of info on early Jeeps, a good timeline of Jeeps, and a cool page with info about international models produced under the Jeep name.

From 93-95 all the ZJs built used a D35 in the rear. The 44 didn't show up until 96, and only behind the V8s. The 96 and up ZJs with 4.0 I-6s all had D35s in the rear. It's also not a standard Dana 44 axle.. it uses an aluminum center section and shares NO parts whatsoever with the iron D44 that comes in numerous other Jeeps. It's called the D44A, not a true D44.

just to add a little to this. the 42re was used on both i6s and v8s since 93. at least in 93 it was used in the v8s, i have one under my hood.

V8 gearing seems to have been sparatic. one thing is for sure, the 'tow package' gave you 3.73's. other than that it was the luck of the draw whether you got 3.55s or 3.73s. i6 are all 3.55s.

I have a couple of observations on CJ transmissions. I worked in a dealership in the early ‘80s and never saw a CJ7 or CJ8 ('80 up) with a t-176 (sr4/t5 with I4 and t4/t5 with the I6) unless it had a V8 (I only saw one of those). If you got an ’80 up Stock CJ with a V8, You got a rare bird (in Calif. anyway). I never saw a t-18 (or a 3 speed) in a CJ after ’79. CJ5s with the I6 after ‘79 (never saw a CJ5 with a V8 after ’79) all had the t176. It never made any sense to me they would put the stronger trans. in the lighter CJ but it is all I ever saw (I think it had to do with the lower 1st gear in the t4). I also never saw a t5 in a CJ5 (but I don’t think Calif. got any CJ5s after ’81, maybe ‘80). Maybe this is a Calif. thing like the serpentine belts on Calif. I6s after ’81.

[dyne_ii]

whats the curb weight of a 1990 Yj?

[JohnnyJ]

about 2940lbs

[rustywagoneersdotcom]

86 FSJ's started switching back to Dana 44 rear, which they kept til the last 90 / 91 model year trucks were sold.

[willysjeepseller]

I have been searching for information on the J6000 trucks didn't they have 70's front and rear or something like that. There doesn't seem to be much info out there on them.

[JohnnyJ]

I've never heard of a J6000. The highest number I know of is the J4000.

Joe Schaefer explains the J-Series numbering systems:

>> they (Jeep) went to the J-10 and J-20 series in 1974. The 200/300 series
>> ended with 1965 but that's also when the 2000/3000 came out so they had the
>> 200/300 and 2000/3000 series in 65.
>> The 4000 series came out in 70 and ended in 73 with all the other 1000
>> series badges.
>> Keep in mind the earlier 200/300/2000/3000/4000 all referred to wheelbase
>> length and all could be had in 1/2 ton and 3/4 ton models(some 1 tons).
>> Models broke down to 4500/4600/4700/4800 etc. The later J-10/20 referred to
>> GVWR tonnage. All J-10's are 1/2 tons and all 20's are 3/4 tons but the J-10
>> could be had in two different wheelbases. Confusing isn't it?

The only D70s I know of were in the rear of the military FSJs (M-715 and its derivations) and Gladiators had them from start of production until 69 and they were only on dual rear wheel trucks.

[willysjeepseller]

I think they were pretty rare. If you search you can find a few for sale but that's about it. I think they were a camper special.

[WA-HCRC]

what is the transmission code for the new 6 speed in the rubicon? i was thinkin about gettin somethin trick since my ax15 is startin to get pretty haggard.

[carnuck]

Just a few notes: The J100 was the Wagoneer designator and J200 the Jeep truck. J300 was the camper special, usually with dual wheels.

232 was available well into '71 (they changed the 6 cyl bell pattern at the end of the '71 model year). 258 was available with the small pattern bellhousing ONLY in '71. After that, they shared the larger bell pattern with AMC V8 (likely due to the smaller clutch in the smaller bell getting toasted too easily and bellhousing cracking from the extra torque).

Rear D44 had 2 piece axles.

Front axle was closed knuckle EXCEPT a few drum brake 5 on 5.5" pattern wags made between '71 and '73. (I've seen only 2 personally)

The J pickup was always wider axle than the Wagoneer. Front was the same width as Wide Track Cherokees, but the rear WT Cherokee width is between Wag and pickup (due to the constraints of the rear fenders, even with flares)

All Widetracks have flared fenders, but not all flare fender rigs are Wide Track.

232 was available till late '71 (when the 6 cyl bell pattern changed) Anyone with a '71 or older smaller bell 6 with TH400 auto should contact me. <G> (I know some people who claim it NEVER came that way)

999 auto was available with the 6 cyl in Cherokees and pickups '80 to '86.
T18 4 speed is @4:1 first gear and T18A is @6:1

Front axle was RH drop till '79 and LH drop '80 to '91 except a couple leftover custom ordered rigs in '80. Rears were RH offset till '79 as well.
