Transmission Options For 225 V6

Good morning. Been searching around here for a bit and I'm not finding exactly what I'm after.

I'm helping my dad get his '68 CJ5 on the road. It has the 225 V6 and a T14a trans. I believe its a Dana 300 transfer case but I'm not 100% on that. Just saw the Dana stamp and what looked like a 300.

Here's my question... What transmissions bolt in with no or minimal effort? My dad has no problem buying adapters from Advanced Adapter as long as the end result works. He would really like a 4 or 5 speed trans if we're upgrading. From what I've seen nothing will just bolt in easily. Now to me? We fix the T14 and run it. The larger gears inside are chipped though and I'm sure it wont be a cheap rebuild. We don't have and transmission shops close so it's been a pain getting any information. I know absolutely nothing about jeep running gear, so please don't feel bad talking to me like I'm an idiot, because I am in this regard.

This Jeep was parked for YEARS over a GM power steering upgrade, I really don't want to see it sit another few years over this transmission issue. Oh, and this will be a slow cruiser build. Mostly under 55 mph for short spurts and some light rock crawling. Pretty much a trail rig that can hit the highway between trails. Thank you!

 

If you want an easy bolt in trans, find another T14. There's several different 4 speed swaps that will work but none are an easy bolt in. Do a search, 4 speed swaps have been discussed a LOT on here.
Forget about a 5 speed, they are too long for a short wheel base CJ.
Oh, and your tcase should be a Dana 18 (rear output is offset to the passenger side)

 

I just did a t14 swap in mine, from a t86. Pretty basic.

 

For my 67 CJ I have a T18 4 speed and a Dana 18 with a Warn overdrive because of the short wheelbase. I'm building a 67 Jeepster so it's getting a AX15 5 speed and a Dana 300. Both have the 225 V6 but the wheelbase is a huge factor.

 

T14 is pretty simple to rebuild with basic mechanic skills. Novak adapters can provide parts & a rebuild kit.

Pretty much this. No Dana 300 will work behind a T-14 due to the 10 spline output shaft.

 

Perfect! Thanks everyone for the information. I'm really pushing him to stick with the T14. The 3 speed will work just fine for what he wants to do with it, if he wants to get more into the rock crawling game, Ill be pushing for a whole new motor with fuel injection anyway.

 

You can fuel inject the 225…
There’s a whole thread about different options and what it takes.

 

I've found the 14 to be marginal at best, while adequate for DD'ing, it is still the weak link and hard parts are getting difficult to find.
With the early two piece bellhousings, swaps sans the adapter are easier. I opted for a T18, but other transmissions will work.
Upgrading the transmission is, IMHO, money better spent than any engine swap/upgrade.

 

Snowshoe had a destroyed t86, I put a T14 in. Now I am gathering parts for a T18 swap.

 

Bite the bullet and swap in the SM-420, yeah, needs an adapter, but well worth it..

 

Good info about 4 speed swaps-

Another that would just be sticking with the T14 for this application. That is a way better transmission than a T90 and especially so the T86AA. They will take some abuse. If rock crawling is your thing you can do better with the truck 4 speeds but as noted, NONE are bolt-in. A T14 will stand some moderately difficult wheeling.

 

This is exactly what I needed everyone. Thank you. I swear I did search but didn't find what I was after, mainly because a lot of the terminology is above me with these trans. I'm hoping to find a used T14 to get us through until we can find a adapter only 4 speed. He's fine with spending the money on adapters but if it requires changing input and output shafts or any other internals, I know it will never happen. The post about understanding 4 speeds was very helpful.

 

The most important thing you can do is get it running and driving using what's there currently. Upgrade as needed. Otherwise like you said project will get stalled for who knows how many more years

 

I completely agree with Jeepstar.
If your project stalled on a steering swap, it may be better to just put back in the transmission that was there or take/ship it for a rebuild. Herm the overdrive guy and novak used to sell whole transmissions. My sm465 swap was one of the harder projects on my Jeep due to all the peripheral changes that needed to be done. Clicking "add to cart" is alot more fun than the next part of spending many hours on your back under the jeep.

 

Unless you find one already adapted, pretty much any truck speed short enough to work well when adapted will need the mainshaft (output shaft) replaced which means tearing the transmission apart. The new mainshaft comes with the adapter kit. There are ones that don’t require the mainshaft to be replaced but those will be significantly longer, by several inches. When you are talking drivetrain and short wheelbase every inch shorter counts due to driveline length and universal joint angles.

 

You will find information easier using your favorite search engine (Google, Bing, ....), type in "earlycj5.com" and follow that with phrases like '4 speed swap' or 'T-14 rebuild' there is a TON of info available.
