What transmission is this behind my 170 S6?

Looks like an A230 three-speed to me.
Behind a slant would mean it has the close-ratio gearset.

They are easy to ID. The smaller, lighter gearbox with "grind 'er into 1st" (no syncho) has a top access cover. The larger, better, heavier, fully synchro box has a side cover similar to a 4 speed

Does the A230 have the same removable bell housing?
Same bolt pattern to the bell housing as say the 833?
Meaning can I get the same V8 4 speed bellhousing and this transmission will bolt up to it?
If not, what would I need to get to bolt a 360 to this A230?
(I am simply looking to see if this is an option, not looking for everyone to tell me to swap it for the 833... I will go to a 4 speed later, what I am wondering is being the A230 is already in my car and working fine, if I can pull my S6, swap the bell housing, and swap in my 360?
And IF so what is required because if possible then I will do that and look into transmission upgrades as the next project)

Bellhousings from about 1970 onwards have both transmission bolt patterns (3 and 4 speed) on them. Just make sure you get a bell with the right size hole for the transmission's front bearing retainer.
If it happens to be a dedicated A230 bellhousing, no. The three and four speed bellhousing patterns are different. That said, as mentioned, it "should" have both patterns on the bellhousing.

But I mean the only bell housing I have currently is in the car with the /6, so obviously I would be buying another bell housing to bolt the A230 to the 360... but what I see from the comments is that I CAN bolt the A230 to my 360, I just need to be sure to get the bell housing with both bolt patterns and big enough hole that the bearing retainer fits, correct?
Would it be safe to assume the bellhousing I would be getting would also have the ball/trunnion set up that I can also use with my current clutch or do I need to look for specific year bellhousings for that?

First, what vehicle are we working on?
Second, the ball and trunion has nothing to do with the clutch or bell housing. That only pertains to the transmission and drive shaft.
As far as I know the A230 trans did not have a ball and trunion setup.

If you have an A230 with a B&T output to fit an early A-body, then it's a custom build, cuz the A230 didn't become available until around 1970/71.
And if that's the case;
As I recall, from the 80s;
the back-end of the factory A230 and the mainshaft, can be transferred to the A833.
If this is true, my memory could be wrong, then you could swap those parts and be golden.
But
More likely is, that when the previous owner installed the A230, the driveshaft would have been modified with a slipyoke. Thus, you'd still be golden.
But I just gotta say; Ima guessing that picture is of an alloy box and cover..... which, if an A230, I have never seen.

My apologies, a 1967 Valiant. And I thought the ball and trunnion was related to the clutch linkage arm, I didn't realize that was the proper term for the typical u-joint.

A230:
Iron case, aluminum side cover.
There were several case variations, but nothing pertinent.

Does an A230 have those ribs on the bottom of it like the OP's pic? Shouldn't all A230's have a shifter mount on the tailshaft like 833's? I was 18 years old the last time I had an A230 in my hands.....and that was 50 years ago!

The center holes are sometimes machined to fit the different bearing size. If you have the smaller one sometimes it can be machined a bit larger to accommodate.

Yes, some-not all cases had the ribs, as said there were variations in the case but nothing major.Does an A230 have those ribs on the bottom of it like the OP's pic?

Here are a few more pics, later I will check the other side for any vin information, also a better pic of the information on the cover (blue arrow)...
And I am figuring it mush have been swapped by the p/o and you can see in one of the pics the slipyoke

It appears that the OP can find a dual pattern small block bellhousing and swap to a V8 and not have to fool with the transmission until he is ready to swap in an 833.

It does have the shifter mount on the tailshaft and now has a floor shift not column like it did originally.Does an A230 have those ribs on the bottom of it like the OP's pic?

Yup... pretty sure that's exactly what I got.

Exactly what I was trying to determine and seems like you are correct.
It's not the term for a typical 4-trunnion U-joint, a Ball & Trunnion has 2 trunnions that slide in a housing typically used today for FWD/AWD 3-trunnion inner CV joints. It hasn't been used on Mopar propeller shafts since '65, at least passenger cars that I'm aware of.
Someone swapped in the heavy duty A230 at some point, probably when the floor shift conversion was done. The 67 transmission should have been the small A903 3 speed.
Yes, as long as the bearing retainer diameter checks out as mentioned above, that will work for You. The good news is You can have fun with that A230 'til You get the A833, I've known a couple of guys who pounded those things, they're pretty durable.
Just some friendly advice, but if that was my project, I'd put that A230 behind "whatever" V8 you put in the car and never look back. No reason for a four speed, unless you just want to spend more money. The A230 is every bit as strong as the A833.

Glad i asked because I would have assumed it was something inferior when like you and @Killer6 said too... I will just run it.
I sure as heck would. They are stout transmissions. Somebody did good when they swapped it in.
