What is wrong?

I think that also would depend on if the F134 and trany/tc were from a CJ or out of a pickup or stationwagon.

 

To properly adapt your v6 to a T90, you also need the long input shaft. To install this requires a complete tear down of the trans, which is a good time to rebuild it. Refer to the Novak webpage referenced above, lots of good info there.

 

AS posted by 04sd2, this jeep came originally with the T-14 tranny not as I said T-86aa. The adapter he linked to has the proper bolt pattern for both the T-14 and T-86AA but if you do use the T-90 with the J truck input shaft then the adapter will require re-drilling to match the T-90 bolt spread. Also if you want to use the modified T-90 (longer input shaft) you have to count the internal teeth on the input shaft which has to be 18 as the J shaft only comes in 18 tooth. The shaft size on the J shaft is bigger so a new clutch disk will have to be used. If you go the route with the T-14, you will have to know that tooth count you have in the transfer case. The T-14 works with the large mouth D-18/D-20 transfer and has a special output gear specific only to the T-14. Lots to ponder.

 

Don't just assume its a 69. My CJ5 is also titled a 69 but is more than obviously a 67 or 68 with the T86AA. I think the best solution to the arrangement is to find the long input shaft and long adapter and hope the trans is a T90A. If it is the C version, I would find another T90A or convert it. The other solution is the T14 but that will no doubt involve finding a large index D18.

I don't think you can use the T14 adapter with the T90. The bearing retainer won't index properly and the shoulder that the throw out bearing rides on won't be long enough. I think you need to get a T14 and a large hole tcase or get an adapter to go from the T90 to a GM bell housing and a long shaft. I got a new shaft and a used adapter from Herm.

seems to me . the fix would be find another , bell housing with adapter , or 71 bell housing with adapter cast in . T14 transmission and large hole transfer case as a unit. would make it more like stock .like you want

 

I am not sure what to do. I want to go the cheapeat route because it will only be a play toy and will not see much mud or rocks. I do have some other parts that I could use. I will post pictures tomorrow to get some advice.

 

Ok, I have an update. I have several different options I think. I need some advice on what the easiest and cheapest route to go. I have a T98 adapter that was on my jeep and some point. I have a 10.5 inch clutch and 7 inch long input shaft on my T90. I also have a bellhousing that originally came off of my T90. What is my cheapest and easiest option as I am on a budget.

You know, it is entirely possible that your 69 came from the factory with not a V6, but a F-Head 4 cylinder and some one swapped in the 6. Is the front drive shaft fairly thick, like the rear one, or is it about half the diameter of the rear one? The thick one is for a F-Head and the thinner one is for the V6.

 

I can see how that could be possible, however, with the factory engine mounts, the wiring harness being original and the 2 stick transfer case, I believe the engine is original and the transmission and transfer case have been changed.

Mmm. I think it's more likely that it started out as a F134. Pretty sure a F-head Jeep of that era had a 2-stick transfer case.

Well, this is an ugly home-brew setup, but what's wrong with it other than the floor pans not matching? Does it run and drive ok? If you want to save money, leave the drive train alone and modify the floors.

I don't see anything related to T-98 here. If you have some oral history of a T-98, the Jeep could have had a F134/T-98 combo, which was replaced with whatever the seller could find.

Are you thinking the adapter you show is a T-98 adapter? That looks more like a GM-to-T90 adapter. The T-98 adapter is nothing like that - it's a flat plate, about 3/4" thick. And it only works with the F134. That's a F134 bell sitting on the ground in your pictures.

I suggest you take a step back and post some more pictures of what you've got now. Engine compartment, drive shafts, etc.

 

The bell housing you are showing is for a 4 cyl engine not V6 and the T-98 adapter (is it front or rear) is not pictured? It's very obvious that the parts you are showing in post #29 were never working with your 225V6 engine. The frustrating part is that you have to locate and purchase the required parts necessary to make this a drive-able rig. Have you thought about finding a cheap parts jeep? That may be your cheapest route.


Tim had already posted while I was in the middle of this post so he covers all that I said. Check frame vin to confirm engine type.

 

I have a 1968 CJ5 factory v6 and will be replacing my t14 with a t98. It will not happen for a couple weeks tho. But eventually will have a t14 ready to bolt up to a 225 V6 for sale. I did install a twin stick kit on my D18 transfer case.
