Transmission and Transfer Case Variants and Types in CJ's (53-86)

[Rescue Diver]

Thanks for the information I believe that have the t 176 because when I checked oil level the shift was just above the level hole in the case, also the case was cast iron. I bought the jeep at my camp and left it there because its not road worthy yet. The camp is 125 miles away and I cant get id numbers off the case to id for sure. untill I go back up. I left food in the jeep and hope the bears dont get at the seats. Thanks again Jack D. aka davenportknives.com

That doesn't sound like a T-176 . They have aluminum cases.

What year is your jeep? I know the T-18 , T-15 and T-150 have cast iron cases, but the 15 and AMC 150 are 3 speeds.

If you have a T-18 call yourself really lucky!

Edit.....
I re-read your post. If your Jeep is an 84, it could only have a T-18 if someone did the swap because they stopped using them in 1980.

Here's a great source of factory jeep tranny info.

swaps happen all the time I have a 86 CJ7
T-18 , Scout Dana 300 (tc146) and six bolt hubs.

Thanks cj for the info. I have determined that the tranny is a T-176 , so now I need help identifying the Transfer Case . I see that some transfer cases have two shifters on them, mine has one and has the numbers C300-15-2 on the back side does this mean that it is a Dana 300 ? it would seem not to be because the illustration shows two shift sticks. Thanks again. Jacknife. aka davenportknives.com

Yep, a Dana 300 , not all have the same shifters...

Hi all, I'm new on here, and glad to be here. My wife and I did a frame off on our 79 CJ7 a few years ago and only put about 200 miles on it since. Retire a year ago and have time to play. I need some info. A buddy gave me a good deal on a really rusty 79 scout with a good drivetrain. 345, granny 4 speed, Dana 20 , and I don't know what axles. Will the 4 speed bolt up to my bellhousing? Axles? Any help would be great. Thanks, Pony Killer 555

That Scout should have a T-18 tranny. Excellent tranny. They also came in Jeeps from the '70s but the scout version is much different. The input shaft and bolt pattern will prevent you from putting it into your Jeep.
The Scout has Dana 44 axles. Also very good. They can be installed in your jeep. To do it right you should have the front steering knuckles cut and turned to get the correct caster and u-joint angles.

That more then likely is a T19 may not be a granny low.Just it will bolt up
if you use a T-18 or T-176 bellhousing.It will bolt up to your Dana 20 .
But if you could find a 1980 Scout tc146 AKA Dana 300 that would be better. You will need the bull gear from a T19.The Dana 44 rear will need to have the spring pads cut off and weld new ones on in a CJ location.
As fot the front like the other guy said. To do the front Dana 44 right you will have to cut of both ears set your pinion angle by doing some grinding.
set your caster and camber cut off 3 5/8"s off the long side weld the ear back on and then cut your axle shaft and respine it.

Yes many Scouts had T19s and some had T18s but pony killer 555 already said it does have a granny low.
And no I really don't think it will fit into a jeep, Check out this link:
The Borg-Warner T18 & T19 Transmissions - Novak Conversions
Scroll down to the "IH T-18 "
They say the following:

This Transmission is a good unit, but not recommended for Jeep conversions due to its unique input shaft and front, stud-mounted style front face.

EDIT: both the T-18 and the T19 have granny low. The difference is the T19 has syncros for first. T-18 doesn't
Either way it won't (easily) fit into a jeep.

My jeep has a NP435 Tranny bolted to the Dana 300 . The tranny has a granny low for the first gear. Do you know what the pros and cons are for that set up?

the 435 is an excellent Transmission . If you have the granny low it must have come out of a Ford. Jeep never offered the NP425.
There are no cons unless you enjoy fixing broken transmissions.

 

[LASTCJ786]

No not all T-18 's have a granny low!
One has a 4 to 1
the other is 6:38 to one

You can take a short shaft out of a T-18 and put in into a T19

I know all T18s don't have granny low. Pony Killer 555 himself said he had a granny low. Yes, He can swap out the input shaft but it still wont bolt up to his bell housing. The bolt pattern is different.
Did you read this post and the link where Novak says the IH Scout Transmission won't fit into a Jeep

Just getting back into the Jeep scene. My first "car" was a 73 CJ5 V8. Man did I spend money on getting that rig "just right".

Just bought a 80 CJ7 . Going to get it back to new condition if I can. Here is one little problem......I was told that I must have an SR4 4 spd. because Reverse is up and to the left.....not down and to the Right. But I can only find shifter knobs with the reverse down and to the right. Any help will be accepted. (This is going to be fun!)

I found this one in white:
Amazon.com: Mr. Gasket 9618 White 3/8-16 UNC Classic 4 Speed Round Ball Shift Knob: Automotive

Or here's a black one:
Hurst 1630103 Black Classic 4 Speed Shifter Knob

Unless you plan on swapping out the SR4 for another tranny, you might look into getting more than the knob. Like a backup SR4 . IMPO, worse tranny ever put in a jeep.

Back in the 90's I had an SR4 behind a slightly built AMC 304 and after putting new bearings in it, I never had any problem.
