Does anybody know if the 5 speed used in the AMC Eagle will work in an FSJ? I think the transfer cases are similar, but not sure about bolt patterns or durability.

Is it an overdrive? Has anybody had good/bad luck with these (pulling a trailer)? I have the 4 speed in my cherokee now, and would like to get the RPMs down at highway speed.

What is you engine, the T5 is not the best tranny in the world.
I current have 1 in my CJ behind a 360, and I have pulled my little boat all over and my big trailer with 1 to 3 ton or scrap on it (yes 6000 lbs behind a CJ :eek: enigine was happy to actually have a load on it, brakes were not)

I am going to swap in a NV3550 shortly.

But yes the Eagle cars had the same power train as the Jeeps, my 2nd SR4 came out of an eagle car.

It has the 360, and I would like to be able to pull a 20' boat without tranny problems.

Just crusing down the highway I would not even think twice about it.

But now, throught in a mossy boat ramp, 4 wheel drive and a bunch of stupid pedal becase say you backed in without the bilge plug....... (yeah you know you have;) ). And it could have problems.
My 258 ate 3 SR4's before I went with the T5, my T5 did have 1 problem but that was from rolling the jeep...

If you can get 1 cheap, I'd try it out while you save up for something better (come to think of it I will have 1 for sale in a week or 2) Just keep your 4 speed to drop back in if needed.

Guessing you have the T-176 now?? Bellhouing will work, but you might have to tap a couple holes....I THINK they most of the t-case flanges,shafts are the same, but somthing you need to check too.

If you do much wheeling I would not use it either, you are dealing with more weight than my CJ.

Did you say durability? :lol:

I guess a T5 is ok as long as you never stress the transmission in any way. The T5 is better than the AX5 of Wranglers, but not by much. Just don't expect it to live long if it is pushing a V8.

I have a T5 in need of a rebuild, and a NP435 will replace it.

So yes, it will work. Should bolt right up.

How about an AX-15? It's supposed to be pretty durable behing a 4.0. I bet a smogger 360 is not much torquier than that. AX-15's can be had for very little money and are all over the place.

Is it an over drive tranny? and it bolts up? Sorry, just not up on baby Jeeps....

A T-5 is a fine tranny, for light duty use behind a I-6.
Not a good choice for a V-8 tow rig.
My personal choices: (5-speeds)
NV4500 (Very heavy duty,likely over kill) 5-speed OD tranny (Never used by Jeep so adapters are needed)
NV3550 (Med duty,likely OK of your use) 5-speed OD tranny Jeep 2000->2005 Very similar to the 3500 used in 1/2 Chev's and others
AX-15 (I think OK but I don't have any personal experance)
AX-5 Light duty

AND my next tranny swap is :

NSG370 Six speed OD, but it will not see HD use only draging around a loaded Cherokee and light trailer, behind a I-6 4.2/4.0/4.6 (I know when I get there)

I had started a similar thread. I am pretty newbish when it comes to all this but I rescueda 1980 cherokee laredo. It has a lot of time till i get to where I will be swapping out the tranny but i was looking at b'js off road and they have adapters to mount some GM transmissions to the stock AMC 360 motor. It has the stock 4 speed auto in it now so I was thinking perhaps a 5 speed tranny might not be a bad deal.. I just don't know really know how to differentiate and what to consider in deciding between 700-R4. TH350, TH400, 4L60E. Thoughts?

Here are the ratios for the AX-15: 3.83, 2.33, 1.44, 1.00, 0.79. So you get a 21% OD in 5th gear. What I don't like about this tranny is the very tall first gear, but I suppose it depends on what you want to use the truck for. It bolts into an AMC 4.0, so I assume it's a direct bolt to a 360. These usually came with NP231's, IIRC.

I've had a decent amount of experience with T-5s - but in mustangs. There is a large amount of after-market support for this transmission due to the mustang. Although, I don't know how much will transfer over to the 4wd version. I know the 1st gear ratio is different. I assume the main shaft is different as well. Anyone know?

Well, for starters, your current tranny is a three speed TF-727 not a four speed, the TH-400 and Th350 are also both three speeds, the TH400 is the heavier duty of the two, but both can be built to live behind a 360 with no problems. (The Th400 has the advantage that Jeep used them so you can find a Th400 case that bolts up to your 360)
The 700-R4 and the 4L60E are the same tranny for the most part, the 700-R4 was shifted by hydraulics, the 4-L60E is shifted by computer, both are 4 speeds and both are ~ the same toughness as a Th350.
If you go with the 700-r4 or 4L-60E I would just use the NV241C t-case rather keep your 219 or 208, since it is the right drop and bolts to the back with no adapters.

Right like I said i am not experienced in this area. What is the most common swap? Should I even be considering changing it out?

There are not any "Common" OD auto swaps, there are a few who have done 700-R4's some have done AW4(?? small cherokee tranny) Ristow has started a Dodge/Jeep 518 project with major machine work, but not any "common" FSJ OD auto swaps that I knoe of.

If you had a 6cyl,there are a few options,but with the v8,you need that extra long input shaft,and spacer,so the shifter don't end up under the dash.
