calling all T-18 freaks

Went out looking in junkyards for an NP435 and had marginal luck only found one without a shift leaver and the guy was kinda uncooperative about taking it down to show me ...so I will wait .
BUT ...I came across a T-18 that was in a 1989 Jeep cherokee
(VIN # J9M18NN137114)...the engine is a 360 it has a 5"
adapter between the gear box and bellhousing the case has "13-01 "on it
What I am wondering is will this go in a CJ with a 258 and how much adapting would it take to hook it to a D300 T case.The shift handle spins around in the top though
So what are the odds of making this work
TIA

Ray-

With Time and Money one can make most anything "work", right?

When I bought my CJ T-18 I was told by the guy I got it from that it was costly to change the long output shaft to the short shaft. I have seen other posts on this board that say the opposite. The bottom line may be at what price you can get the tranny for.

It seems to me that all adaptors have a starting price of about $500 and go up from there but that may just be me. I would check the Advanced Adapers web site. That may give you some "ball park" numbers.

Good Luck!

Yeah
I wasn't looking for the T18 I went looking for NP435 ,figuring if I pick up the trans and have the adapters shipped I am more likley to get it in one piece. I have an Inquiry in with Hicks and am waiting on their reply.
However working in the trucking buisness I am leary of having anything heavy shipped ,especially cross country.but if I have to I have to.
thanks

You might want to look for a 77,78,79 bell housing. It should bolt right up to your 258 and might be cheaper than a new adapter. You could bolt a Ford T-18 to it and would only have to adapt the back end to the D300. You would also need a special pilot bushing and maybe a new clutch plate. Just a thought.

i wasn't aware that the cherokee's had the t-18 available in 89 but that doesn't mean that it wasn't. there have been some posts recently about 80's modles with the tf727 tranny and it is said that a dana 300 will bolt to them. well the 89 should use the same x-case and if so why would a dana 300 not bolt to the back of it? also the t-18 will bolt to the back of your 258.

I was just on the NOVAK site checking out adapters....this trans is still hooked to the 360 bellhousing so it may hook up .The 5 " adapter between trans /bell housing may push it back too far I was just curious if anyone had any solid info on this ...seems everything I read says not to try to use the Jeep T-18 for whatever reason there is.I am still not sure of the condition of the trans.
It looks like the NP435 and the novak adapter may be my cheapest way out with no driveline mods being needed.So I have to keep up the Quest.

I also plan to clock the D300 slightly and do a twin stick setup almost like described in JP magazine ....except for the way they have the notches ground into the shift rails don't seem quite right.I think I can come up with a better setup than that seems like if it gets to bouncing around the sticks may pop out of those notches

Any other Input would be appreciated.

what jeep do you run? if it is a cj7 then the long input shaft will work fine. i helped a buddy put a amc401, jeep t-18 (long shaft), dana20 combo into a 87 wrangler and he had plenty of rear drive shaft and it had the 6.32 first gear. if you are sure that the vehicle is and 89 then the dana 300 should bolt right up. you might call advance adapters because they should know this info for sure. if it is so then i think this would be a great setup for your jeep. make sure that it is has the 6.32 first gear though. not all t-18's did.

Are you sure it's not a 1979? The only Jeeps in the 80s to come from the factory with a T-18 were the 1980 thru 82 J20s. But if it's an 89 with a 360 it didn't come that way so whoever put the 360 in could have put the t-18 in. Anythings possible.

High 5
I wasn't aware of the tranny combo either but that is what it is and the year and engine size is from the VIN #

just for informational purposes
I do have the 1980 T.S.M. here with the power train options listed ...
in 1980 the CJ-7 was offered with 258 and 304 with an optional automatic and D-300 T-case(it does not specify the type of auto trans)it also has optional 3.54 gear ratio with 3.07 being standard axel ratios

in 1980
The T-18 is only offered as standard trans in the J-20 truck with the 360 V8 but not in California.
it is not listed as an option in anything else Cherokee,Wagoneer or J-10
Hope this info helps someone with an Inquireing mind/wwwthreads_images/icons/laugh.gif

Jeep Bob
I don't think with Jeeps anyone can be positive of anything/wwwthreads_images/icons/laugh.gifthat is why I posted the vin in my original post and its condition looked way to good to be a 79.
I am still not sure why the shifter handle spins around in the top.

I am fishing around for a cheap way to replace my grinding SR4 without getting real heavy into driveline Mods.I just want something strong and reliable and was pretty set on the world class T-4 till my kid blew her scholarship now I need to hustle up a replacement trans on the cheap.So i went looking and found this laying there and figured someone could figure it out.

It should be easy to tell by the size of the Jeep. The Cherokee was downsized in (I think) 1984. Before that it was the same size as a wagoneer with the later grand wagoneer being the big one along with the downsized wagoneer and Cherokee. Which side is the front pumpkin on? It should be on the driver side. If it is and you're sure it's a t-18, then it could be one from an early 80s j20 with the np208 transfer case. Other wise if it's on the passenger side and it's a t-18 then it's bolted to a dana 20. You can get a bellhousing from a t-150 and get the short input shaft and bolt it in with a few modifications if you don't mind using the dana 20. I think hicks has the input shafts for about $100.

I got my Ford T-18 at the boneyard for $75 because the shifter spun around on the tranny. I knew the pin had just falling out, no biggie. (the pin and a ground off drill bit was in the bottom of the case!) My 79 had the Model 20 T-case and I wanted a Dana 300. I called "No Excuses" in NJ and they sold me AA's Adapter for $100 cheaper than AA, the very same adapter! In fact, it was dropped shipped from AA. Now I have some pretty nice low gears and a heavy duty tranny.

yes high5 is right.. if you are putting this into a cj7.. the long input shaft will work.. i have one in mine.. its behind a 401.. have plenty of room all the way around.. both driveshafts.. and the shifter comes out right in the middle of the floor opening.. i have always been curious as to why some put the short shaft on.. unless its in a cj5.. i dont see the use of spending the money.. my rear driveshaft is longer now than when it was stock.. and if its bolted to a 360.. just get the bellhousing with it.. and it will bolt up to your 258... to get that d300 in it.. you do need the adapter.. and its pricy.. or you could get a d20 transfer case.. not much different than the 300.. and it will bolt right to the t18.. that is what i am running.. and its probably whats behind that t18 already..

FYI I have a Granny T18 out of a 77 CJ with the bellhousing, clutch, dual friction centerforce, and a dana 20. The tranny was rebuilt by the guy I bought it from then he decided to run an differnt tranny. It needs a shifter but is otherwise ready to go. I bought the wrong shifter from Hicks and it's included, they said they'd swap it out I just never got around to it. I'd like to get $750 for it. Happy Jeepin'

Hey JPS4evr,
When you clocked the T-case did you redrill the adapter or just move it one bolt hole around ,while I am in there I want to do this also.as well as set up a twin stick.
another thing about this T-18 it has a gear on the output side it looks like it went into the T-case which is not attached,
I knew it was a T-18 by the bolt pattern going into the adapter to the bellhousing ,also 1301 # on the case and the cast iron shift tower,but I know there are a whole bunch of different model T-18 some work some don't .
I wasn't really looking for a T-18 so I just noted some basic Info. and the
VIN #,but if this will work I may just go for it ,I have to see what else turns up .the real low gears aren't real important to me just stregnth I don't want to do it again in my lifetime.
All this free flowing dialog is what this board is all about and the input is very much appreciated.
Thanks all

jeepgod,I'm a little confused (not that that's a rare occurence) but, and I'm not disputing what you have, if you take a short shaft T-18 and dana 20 from a cj and replace it with a long shaft T-18 and dana 20 how can the shifter come out virtually in the same place? I only question this because the last cj I saw that swapped in a long shaft from a J truck ended up with the shifter between the seats as W.C. stated earlier.

actualy.. it isn't that much of a mystery... the stock t-18 just about hits the dash in a cj-7 when it's bolted to a v-8.. with the 5" adapter, it moves the tranny back... only 5".. not really that far, and you can bend the shifter a bit so I think it actually fits better than the short one...jeepgods t-18 is in the exact same place my t-5 used to be in my floor pan

oh yeah, and a 2000 tj, 4.0, dana 44, nv3550

well.. i didnt take out a t18.. so i didnt know how it would work.. was concerned about with all the talk on here with the short shaft swap... but as i was building this jeep.. i had the tranny bolted to the engine.. so i just thru on the body one day to check it.. and whaala.. its right in the center.. but i do have to cut some out of the passenger side of the hole for the transfer case shifter.. it has a funny U shift pattern.. that puts it somewhat to the passenger side.. nothing a jig saw wont take care of..

Jeep Bob,
Actually jeepgod and elusive are correct ,I went out and measured my SR-4 from the bellhousing back to the T-case and it is 15" and the shift for the SR4 is on the tail adapter.the T-18 has the shifter on top of the trans and the AA booklet says the case legnth is 11.87inches plus my measurement of a 5" adapter between the bellhousing would only make it 16"and change,so it is possible .But not if you put a D300 on with another adapter on the tail .So in all likleyhood I will not go with this swap unless absolutley necessary.I think I will continue my search for the NP435 since I still have time ...this weekend has been kinda hectic

unhumen, you know the more I look at this the more I think it has something to do with it originally either comming from a wagoneer/cherokee or from a j truck or the previous combination mixed in with whether it was bolted to a 6 or 8. I think we're talking two different long shaft lengths. If you look at the AA catalog they list a t-18 from 1968 to 1981 behind a v-8 with an input shaft length of 14.12". Now follow my logic here but the only jeep offered with a t-18 in the 80s was the j20 so that would seem to imply that this is not the same length shaft from the wagoneer/ cherokee version. you're talking just short of 14" for bellhousing and adapter plus 11.87 tranny length, so now we're looking at a distance 10" farther back than your sr-4 which seems to put it between the seats. So what I must have been looking at was a cj-7 with the j 20 version of the t-18 not the shorter wagoneer/ cherokee version. I stand corrected.

unhuman,
Moving the case one bolt was too far. I redrilled the adapter and didn't use the bottom hole (too close the cast web) I made my own twin sticks and moved it over so they would come out the stock hole in the tunnel. That is to say I didn't have to cut the floor other than a 1" hole for the bolt to hold the shifter to the T-case. I made a new stainless tunnel cover and got the twin shifter boot for it, works good and looks great.
