Default Dana 20 shift pattern?

Okay, We bought a parts jeep ('79 cj7) and it has a t-18 in it. Also it has, what we believe to be, a dana 20 transfer case.

The question is... the transfer case shift pattern is (from dash to back) 4L, Neutral, 2H 4H. A normal dana 20 (atleast every other Dana 20 that I have seen) is 4H, 2H, N, 4L.

It is not a dana 300 because it does not have the round bolt pattern. We are unsure of what the case is. Any help would be great.

Its a Dana 20. Only other thing it could be is a Dana 18, but the offset rear output would be pretty obvious.

Does that mean it just has the other shift pattern? Never seen a 20 like that.

I believe you already told us it has a different shift pattern. Just compare it to the pictures on Novak's site or Google some Dana 20 pics to confirm what it is.

What application are you calling a "normal" Dana 20?

We have had about 10 dana 20's and none of them shift from 4low, neutral, 2high 4high. We just wanted to be sure it was a dana 20 and not somthing different.

Thank you

Think of it like a axle - it doesn't matter what's going on at the ends, what tubes/shaft diameter it has, disco/non-disco, or what the bolt pattern is. Its the ring & pinion construction that determines the model.

As long as the transfer case housing is confirmed as a Dana 20 and it works, cool. Personally, I seem to recall my 78 CJ-7 being a 4L/N/2H/4H from front to back.

Default 79 cj7

I need some help with my cj7. I'm confused on what transmission and transfer case this jeep has. From all the websites and jeep magazines for the 79 cj7, nothing seems to be matching up with whats in my jeep. The transmission shift pattern is: upper left is reverse with 1st to the upper right of reverse, 2nd straight down, 3rd upper right and 4th straight down. It's an
"H" pattern with reverse in the upper left. 79 cj's show a complete different 3 speed transmission. For the transfer case, I think its a Dana 20 but I'm not sure. It looks like an aluminum casing with the pattern being 4H up, then 2H, N and 4L. The boots that are around the shift levers are not what shows belonging to this year jeep. Does anyone know what the heck is in this thing as I'm in the process of rebuilding this and want to get the correct cosmetic parts for it. Also, is it possible this may not be a cj7 and something else instead? like a cj5? What is the difference between them?

Next time, make your own thread. It will get more views.

If you don't know the difference between CJ-7's and CJ-5's, go to Google.com and use it to search for pictures.

You don't have a 3-speed. You have a 4-speed, which is the T-18. The 1979 T-18 had a different pattern than the previous years, that's all,

This is a Dana 20. Note the appearance of the shifter linkage (ignore the word "no").



This is a Dana 300.
