I have a T5 on my 304 v8 for the time being and it has actually held up great even with the additional torque of the V8. I dont do any real hard offroading or anything but its definitely nice to have the 5th gear when cruizing above 50 or so.

I swapped in a NV3550 from a TJ... it wasn't cheap, but with 4.56's and a set of 35's on it... it was really a nice combination.

There are kits out there that gives you most everything you need. We had to source an AX-15 bellhousing inspection plate for the new TJ bellhousing, but all in all, it shifts nice and is really smooth with the hydraulic clutch... yup, I said it, do that as well and you won't have to worry about any issues with the mechanical linkage... update the clutch as well... by the time you are all said and done, you will be out a few g's...

You will need new driveshafts as well... and then you might even need larger wedges to turn your pinion up more depending on lift... yup, lots of things that go into this besides just the tranny...

so silly question, but what's the difference between the Mustang T5s, and the Jeep T5s? Dimensions? Input / output shaft characteristics?

Mainly tailshaft housing. The Jeep and International ones have a short tailshaft housing, I would really call it an adaptor.

I'm not sure if the Mustang T5's were the World Class variant or not, but there are differences between the WC and the Std T5's. The way I understand it, it has more to do with bearing type and syncro material than actual design.

HTH!

so is it just the jeeps t5 being blown up because i've driven a couple of non jeeps. v8 boss 302 (homebrewed) with t5 in early mustang and a 302 bronco and the t5s handle like a champs. They were world class mustang trans. But they were abused

302 mustangs (post '83) typically had a WC T-5 (good for around 310 pound feet of torque if I recall correctly, the Jeep T-5 was designed for around 265 as I recall (if its important, please look up the spec.). The WC T-5 had some improved bearings and oiling. The WC was also used in some Chevy pickups and other vehicles (I don't remember if the splines were the same or different) but they typically came with a higher 3.76 first gear. The mustang T-5 also had a very high first gear and is really not applicable to jeeps because of that (and the long tail shaft).

Enjoy!

I was planning on replacing my SR4 with a T5, as it looks like an easy swap.

What is the best way to determine if I have a 10-spline or 14-spline trans? The VIN on my 1981 says it came with a 4-cyl, but the PO swapped in a 6-cyl. I assume the SR4 is still original, but who knows?

If you really want to do something different, I'm sure it wouldn't be too hard to get the NSG370 (TJ 6 speed) in there.

Ford and Jeep= 10 spline
GM maybe rest is 14 spline
Mustang T5 for 4 cylinders has also thinner input shaft

I would not assume that.

And the gear ratios.

Jeep used the 14-spline behind the 4-cylinders, also.

something I just want to put out there to consider is the overall gearing range of a transmission. a T-5's range is about 4.9 and my t18's range is 6.32 and I'm sure no one will debate that the T18 is much stronger than the other trannys mentioned(except maybe the NV4500).
Of course the T18 has large gaps between the gears and long, slow shifter throws.
