My comment on the T4 may be unfair, since it is being asked to do something it's not designed for, I am a little frustrated with mine and yes the gears definitely aint helping.

My thought on the Toyota axles are based on seeing them in a 304 jeep with 38.5s running stock axles that is bogged hard and has been for several years without issue. The guy had an extra set of axles just in case but hasn't had to use them, they are beefy to say the least. Thinking back I have bogged with many Toyotas over the years and never seen an axles failure, large tires but granted no HP. They are 56 inches wms to wms, they come in 4.10s, 4.56, & 4.88s fromt he factory and are 6 lug Chevy (matching a set of wheels & tires I have). They are affordable and a quick and effective bolt in. I have a 60 or a 14 I can cut for the rear but the front is the challenge.

465 seems very doable and even the 205 for expense. Is a 205 a chain or gear driven t-case? What about a 203?

Thanks for info so far and keep it coming.

Does the T176 require an adaptor to fit the 300 or are they ALL already set up for it?

Novak doesn't list an adaptor for the T176.

The Novak site appears to imply that the installed length for a 465 with the 300 as the same as a T4 with a 300, indicating the drive shafts wont have to be modified if I do the tranny swap before the axles. This two step process could make it more cost effective and buy me time on my axle decision. The T176 swap would require modified shafts.

A T-176 will replace the T-4 exactly and I believe the T-5 also. And all fit right up to the Dana 300 Tcase.

Over 2 inches different in length T4 to T176 (shorter) which well move t-case forward 2 inches causing drive shaft mods, or at least that is what I have read. Novak site confirms the length difference. Surely someone has done this and can comfirm one way or the other.

Young kid driving it? NV4500 and don't look back.

It is THE strongest stick trans you can reasonably put in a CJ.

17 yo, but it broke once on me in 5 miles on dirt, ever since then he has been scared to take of over idea for fear of it braking and him not having his new Jeep. I think aftermarket (chinese?) inards aint helping either, the original was popping out of gear when we got it, so we pulled it day one. Had a friend of mine (35 year pro tranny guy with extensive performance backgroup) build it for convenience, replaced most everything inside and it wont last. I don't think it is his driving style, because he would tell me, no need to lie cause he would get in trouble although he would if he lied. I cant rightly get on him for stuff I still do.

Not to mention I drove 6 hours home and played a bit, the boy I got it from drove it pretty aggressively on the test drive as well, even though it popped out of 1st it didn't brake.

Just to re-chime in. Yes, some of the older truck trannies are as or more stout than an NNV4500, but I like the 4500 for a few reasons. Obviously, 5th gear overdrive. The closest trails to me are like 2 hours of highway driving, and she's no trailer queen.

Next, while not a Getrag in a BMW, the 4500 shifts very smoothly for being a one ton truck tranny.

Lastly, its much newer than the NP435 or t-18, etc. I'm hoping parts are still easy to.come by in 20 years. Although the 258 does not even come close to taxing it.

Not so. I replaced my factory T-176 (it broke) with a T-4 and it bolted right up with no mod. That was on an 82 CJ7.

Thanks for the info, nothing better than experience to know the facts. Just curious, how did you brake the T176?

I put a NP435/dana300 in mine. Pretty simple rebuild. You can get an adapter for 435 to Dana 300 from Novak. The bell housing from the T4 can be drilled an tapped or you can pick one up from a t176 or t18a. I have the same rear gears as you and run 33 inch tires. I basically have a two speed transmission. Unless I hit the highways for a few miles I rarely use 4th gear and the granny low is only used on rocks and steep inclines.

That's an interesting thought, since I am a Mopar guy and have a slammer with a 435 in it. I called my self looking for the adapter on Novak and didn't see it (found it). It was actually one of my first thoughts, how strong is the 435?

I guess I my be better to answer my own question cause I have trashed my truck for 15 years or better with no tranny issues. Not a lot of HP, 3.55s with 38s and a LOT more weight. VERY INTERESTING!

NP435, T18, SM465, SM420 etc. are all heavy duty transmissions. You'll find any/all of them in up to 2.5ton trucks.

ANY of them will stand up to lots of power and torque. Find the one that fits your driveshaft length/adapter/whatever needs and go with it.
