Well I picked up the Tranny/TC today. Nowhere on this huge chunk of metal could I find something saying T18A but appears to be a T18A. I marked and rotated the input shaft and it took 6 rotations to make one full turn so I'm assuming it's the (6.32:1 first gear), therefore a T18A. (There is a stamping on the cylindrical portion of the front output shaft that says (T-18-6) though (Last Pic). I'm guessing this is from a 78 model by looking at one of the tags but I can't be for sure.

The owner of this combo said it came from a CJ but here is my confusion:

NOVAK shows a line diagram for a Ford T18A that has a rectangular patten but with a knotch out of the rear left corner? (Which is how mine looks from the pic that I took of the gears)? http://www.novak-adapt.com/knowledge/t18_t19.htm

Off-Road.com's site shows the exact same model number embossed/stamped on the article's tranny as I have embossed/stamped on my tranny. Makes me think I have a CJ T18A since this guy physically pulled his tranny from a 79 CJ5? http://www.off-road.com/jeep/tech/convtrans/cjt18/

I had a T18 and it had the 13-01 on it too... Looks exactly like the one you have. Main difference on them is where the reverse gear is located. Jeep transmissions had it on top, towards the passanger front tire IIRC...

Whats the question??

That T-18 and Dana 20 came from a Jeep CJ, but I am not sure which year. The lack of the large bump on the driver's side of the case indicates it's from a later year- a quick check of the shift forks will tell you. The early models had bronze forks, and the later ones had aluminum. Also, the early T18s used an 'over and up' motion reverse, and the later ones used an 'over and down' motion to obtain reverse. I know it's a jeep case because the bell housing bolt pattern gives it away. Only jeep used the funky design where the driver's side bolt tabs were cast in close together, and the passenger side tabs are in the normal position.

The small gear on the input shaft looks like a 6.32 low version. The 4.02 first gear models used a much larger gear on the input shaft.

Nice find!

Thanks for the info, managed to scoop it up for $250 complete as pictured and in Hawaii which was a miracle since it's such a small island and everything is picked over or sells fast~ :D

77-79 CJ's had the T18a as an option. I have had several people tell me that they were only behind the 258, but mine is a 304 with the T18a. The PO had all of the documentation from the time that it was bought from the dealer till I bought it.

The factory did make the T-18A behind a 304. I personally have seen two of them.

The tranny in question belongs to a 78 CJ

I have one from a 78 cj7 with a 6

The IH T-18 uses the same bellhousing patern.

if the drivers side upper and lower bolt hols are closer together than the other sides its definately out of a CJ

What you can't read today?:flipoff2:

It appears identical to the one I pulled from a 78 cj7 with 6cyl. that had the correct vin # for it.
good luck

I always thought the IH cases used studs screwed in the case- I remember these cases not having the ears that line up with the holes in the bell housing.

Same as my '78 CJ-7 Golden Eagle.

quote from that link:

"IH T18

The IH T18 was available only in a close ratio (4.02:1) version. This transmission is a good unit, but not recommended for conversions due to its unique input shaft and front, stud-mounted style front face. "

IIRC, the front of the case has no ears on it, but rather four holes to screw the studs into.

It's been a while since I rebuilt a T-18, but I did do a few of them and remember something a little different about them that did not make them usable for a jeep or ford applicaiton, unless the user wanted to swap in an IH motor.

1979 was the only year for t-18 and 304.

Ok, it's right there in print,,,, This does not Jive with the IH T-18 I had in my possesion in the past. Possibly the one I had, had been modified. It was the same bell patern ( same ears ) as the CJ tranny to bell mating surface. I purchased the tranny from and IH guy, who had never owned a Jeep.

that's odd.

Was it a low ratio (6.32) first gear?

1979 was the only year for t-18 and 304.


Not true.

I have seen and driven one '76 and one '77 model CJ, both with factory equipped T-18s and 304s. Both were also the 4.02 first gear, not the 6.32 first.

I have another fried with a '79 CJ7 and his did come with a 6.32 first T-18 and 304. He bought it new and showed me the window sticker:eek:

that's odd.

No it was a wide ration, much to my chagrin. I had it mounted to the D20 and the factory T-14 bell. and was I ready to install it, when I discovered that little bit of info. This is how I know it was exactly the same pattern. Now it could have been a Jeep tranny but that seems unlikely.
