Transfer Case

[Vick68]

Ive got a ? I have a T-18 4 spd I know that for a fact but I do not know which Transfer Case I have mounted to it. I cant see anything on it to tell me. I'm going to try and get a pic of it and post it. What are the possibilities that could be mounted on the T-18 . It doesn't have twin sticks, it doesnt even have a shifter really the PO had what it looks like a file mounted to engage it as the shifter. It looks like it engages the 4wd just by pulling back on the shifter. If thats the case, would it have a 4wd low in one spot and then high in another or do you engage the 4wd and you have 4wd?

Vick68, here is a photo of a Dana 300 TCase installed. Take a look beneath your machine and see if you can spot all the plates, bolt patterns, and stuff sticking out to confirm or eliminate your Jeep has a Dan300. Sorry 'bout the clutter around the Dana 300 . It fell on me once, so forever after I will rig a safety harness and wooden support. I trust luck over skill, else I'd have a busted collar bone.

You should have a Dana 20 Transfer Case . Check out this link: http://www.jeep-cj.com/forums/f105/transfer-cases-12108/#post97070
You can tell it from the Dana 300 by the way the shift lever is mounted. The Dana 20 has a tubular bar coming out the front that the shift lever is mounted on. This pic has an after market twin shift but that tubular bar distinguishes the Dana 20 . Otherwise a Dana 20 looks much like a Dana 300 .

If your jeep was older than 1972 it would have a Dana 18 but those come from the factory with twin shift levers. Plus the Dana 18 has an offset rear output so the rear diff would also be offset on the axle.

The most likely is a Dana 20 with the "texas" bolt pattern where it mounts to the Transmission . The T-18 rear plate is about 1" thick that the Dana 20 bolts to.

The next choice would be a Dana 300 which has a round mounting area to the Transmission . I am assuming you have a centered rear diff.

My Dana 20 shift pattern is 4HI - 2HI - N - 2LO - 4LO . The 4HI is up or all the way toward the dash. The 4LO is all the way back. There is a 2LO notch, but it is not marked on the knob. The trick is to find neutral for a reference point and then one click forward for 2HI.

The most likely is a Dana20 with the "texas" bolt pattern where it mounts to the trans. The T18 rear plate is about 1" thick that the D20 bolts to.

The next choice would be a D300 which has a round mounting area to the trans. I am assuming you have a centered rear diff.

A Dana 300 behind a T18 in a CJ5 is problematic due to the short rear driveline the combo creates. The only real option if you want a Dana 300 in this case (a CJ5) would be to find a 1980 Scout version with the “Texas” bolt pattern (same as the Dana 20) which are rare and expensive if you can find one, as the adaptor for the T18 to a Jeep (round bolt pattern) Dana 300 is 3.2” long and costs about $500. In addition the Dana 300 is longer than the Dana 20 for 2”-3” more depending upon model year (1980 being the shortest). All this shortens the rear drive line by 5”-6”. You can get some of that back with the super short output shaft kit but there goes another $600 for the parts and even then the rear driveline will still be shorter than you have now. If this was a CJ7 you have the extra room for the boxes and adaptors but a CJ5 is just cutting it just too close in my opinion.

So most likely its a Dana 20 . Tomorrow I'm hope to look at it better. Maybe clean it off a lil bit. I got to try and find a shifter for it now.

The Dana 20 is a strong case and you already own it. Shifters can be had, check Craigs List.

This is what a Dana 20 looks like on a T-18 .
