what tran do I have, pic alert

[73CJ5 Michael]

got this tranny-T/C today, guy says it is jeep, but don't look like that's what it fits.I'm fairly sure the T/C is a 21, and guessing the Transmission is a warner T-18 with the 6.xx first gear. the Transmission input shaft is (best I can measure) 9 1/2-10" long, the mounting bolts on LH side are 2 1/2 inches, the RH side are 4". I'm wanting to put this in place of a shelled 3 speed.... oh yea 73 CJ5 AMC 258 i6 / 4.2l engine

WELCOME
Pretty sure it's an '18'. My CRS is in 'bloom' at the moment.
Can you post the numbers in you last picture near the shift colume and any other numbers/markings on the tranny and t'case to confirm ID?
Pictures would be best--

thanks Lumpy Grits
I been studying novacs site ,,,..its an '18',,on the top cover is 13-01-097-907,, on the case LH side, just above the Borg-Warner is 13-01-065-906,,,what is throwin me is that different input bearing retainer an that different mount bolt pattern
so,,,what am I gonna need to get to put this in place of the trashed, I think T-14 , 3 speed? different bell housing, bearing retainer? sure like to get jeep going again
oops, my bad, the Transfer Case is a 20, not 21

Novak's C/S could help you, using the pictures and info you just posted.
It's where I would go next.
Let us know what you learn.

I have to second it is a T-18 . The front bolt pattern appears to match the 1977 to 1979 CJ T-18 . The stock T-14 bell housing I assume is in your jeep won’t work. I also believe that the 1972 to 1975 CJ T-18 had a different bolt pattern than the later ones. (Notice I left out 1976. 1976 was a bastard year with a switch over from the earlier close ratio T-18 ’s (4.1) and the wide ratio (6.32) at some point during the model year but nobody seems to know for sure when during the run that happened.) Easiest bell housing fix is to find a 1977 to 1979 CJ bell housing, either AMC I6 or V8 will work as the back of the motor bolt patterns are the same.

The next issue is that the stick out length of the front shaft. The stock CJ shaft is about 7-1/2” (Ford version is a little shorter) and yours has a 9-1/2” to 10” shaft. The T-18 is too long to push the Transmission back any further than 7-1/2” stock bell housing length in a CJ5 or the rear drive shaft will be too short. Looks like a new shaft swap is in order.

Also the Transfer Case shifter placement for the Dana/Spicer 20 on a CJ will be further forward to the front of the Transmission than what is shown in your picture. You made need to alter the floor to make it work.

OK, I'm back. I had to register again as my original password/login stuff wouldn't work at all, never got e-mail to reset password etc. if I hafta to register again prolly won't come back but will lurk here sometimes.
saddle tramp,
with a lot of research on this site and Novacs I have found that is exactly what I have, T-18 with a long input shaft, novac has a conversion input shaft.
thanks for the info on the bell housing I need. I think I can farmer up the Transfer Case shifter for the moment, novac recommended the 2 stick shifter.
next issue is the driveshaft length, the T-18 is about 4" longer than the 3 speed its replacing, with a 4" lift I can see this is gonna cause problems, has anyone put a reverse rotation '44 in the rear to help with driveline angles? will that even work at all?
thanks to all for your help

 

[Torxhead]

Michael, I would suggest a constant velocity u-joint with rotating the pinion angle up to match the driveshaft angle.

sooo,,,, nobodys tried a reverse rotation '44? just from some wag measurements, only gonna be room for a slip an CV really short tube,,, Yea I know a Reverse '44 is gonna be a custom build,,,then I can upgrade lotsa stuff,,,disc, locker, full floater....what ya'll think

Don't give up. The site has been having problems for a while. You should be able to log in if you have Tapatalk. As for your setup, I didn't see what you are putting this Transmission into. We have a 79 CJ7 with a T-18 out of a 78 J20 truck. It still has the long input shaft and adaptor with a very short rear driveshaft. We are using a double cardan joint, and at 65mph it runs smooth as silk. Just make sure the pinion is pointing straight at the Transfer Case output yoke and you should be fine. No need to mess around with the gearing. We have an Eaton E locker in a Dana 44 with standard cut 4.56 gears. Nothing fancy or custom.

what is tapatalk? I'm pretty sure I don't have that, just a plain ole desk top.
this is going in a 1973 CJ5 , AMC 258 i6 / 4.2l , with 4'" softride lift,,,, rear driveshaft is already got quite an angle and short, with the trashed T-14 3 speed. I'm adding about 4" length with the T-18 . really cant go with the J-20 adapter, then I think I could just connect the Transfer Case direct to the rearend, might have room for a short slip joint
what is a "cardan" joint? is that same, or another way to say a CV joint?
ifn ya don't know, a reverse rotation Dana puts the drive pinion on the "top" instead of on the 'low' side of the differential, and are really a stronger unit, was common in the mid '70's fords, that would really help with driveline angles. that's why I mentioned a custom built unit
if ya don't here from me again ....well,,,,the password didn't work,,,,
thanks again,ya'll been lotsa help,,,,

Tapatalk is for your smart phone. I have a windows phone, so it does not work for me, but a lot of other members love it. You're right, a long shaft T-18 won't work in a CJ5 . You can get the shorter input shaft as you already know from Novak, and other places. I know what reverse rotation is. Just seems like a lot of unnecessary expense. Just shim, or preferrably reweld the spring seats on your axle in order to achieve the proper pinion angle. You are correct. A double cardan joint is a type of CV joint where you have a double universal at the Transfer Case yoke. You rotate the rear axle so that the pinion points directly at the Transfer Case output yoke. Our rear drive shaft is only around 19" long, and works perfectly. Hang in there!

I'm back one more time,,,, also know as Michael V 73CJ5, Michael V, 73CJ5 Michael,
I'm sure getting good at registering
mriplaybass,,,I figured ya knew what reverse rotation is,,, I done some lookin around and that is really the wrong terminolgy,,its reverse cut, hi pinion and theres a couple others I cant recall right now,,oh yea,,love the tag line, I'm the same way
I don't have a 'smart' phone, don't really want one, so the tapatalk isn't gonna work for me
I was just thinkin the Hi pinion would be a neat trick to put in a lifted jeep, specially a 5 to help out with the driveshaft issues, has anyone done that? I looked at Curries site, that's a little more extreme(read $$$$) than I want or need to go, there's got to be some others that build rearends, I just haven't found em yet. I could do in the neighborhood of $1500 + or - for hi pinion or am I way to low? I know lockers, disc brakes an such are gonna add up quick
I'm looking for a bell housing for that T-18 if any ya'll gots one layin around(77-79 CJ)I'll put the input shaft conversion in it
ifn I don't come back,,I'll just be lurking,,
adios all and thanks for the help!!!

First of all welcome to the forum!

Second...DONT LOG OUT if possible. This site has login problems which were caused by some damaged/corrupt data. It is in the process of being transferred to a new forum software, but it may take a while to convert over....yes it's been awhile with problems, but there is a solution in the works - just cannot say when. Sorry for all the problems - we don't want to be losing our new members.

My better half is mriplaybass or "Bass" We have a build going of a '59 CJ5 which we are going to put a recently aquired short shaft T-18 in place of the T-14 thats in it now. Of course the Transmission adapter we bought for the the 231 V6 will have to be changed. And other stuff, but after using our 79 CJ7 in CO with the T-18 we want to change the '59. Here is the build thread for that one: http://www.jeep-cj.com/forums/f98/1959-cj5-one-piece-time-21347/

Let me ask Bass if we have a bellhousing that would work for you....hang in there! Great folks here please don't give up.

I have tried the not logging out ,,, well that works for about a day, then I guess no activity automatically kicks me off,,, then here we go again.
