Does anyone know for a fact what are the range of tranny codes that apply to the '67? If so, I'd like to be steered to a source (reliable on-line table, preferably). I've never been able to find a definitive source for this.
As a bonus question, does anyone know for a fact what vintage this tranny code applies to (Hint: it's a swing arm - not IRS):
AO 360465 |

That site doesnt cover my tranny code either. Looks like data for 65-68 is missing everywhere. I have a thread on the same question. No idea how to find what mine is.

Look at the URL listed by VeeDubDoug and note the subtle difference vs. this one:
http://www.midsouthvw.com/TechTips/tech_tip_TransaxleCode.htm
Doug's give this:
KG from 08/70
The other one gives this:
AO 1300 3.875 KG from 1971
This is what's frustrating: everyone has a different idea. I have a hunch they may be compatible in this way: 08/70 is the nominal manufacture date for 1971 model year (but they should be explicit).
Regarding the 2nd site (1971), some insist that 1971 is IRS! Yet I assure you the one I have is swing arm.  |

My transaxle, which I believe to be a 68, starts with a D....no other letters. In the USA, there were no beetles without IRS after 68.

Yes. I don't see rear axle numbers after 65 unless I'm looking at it wrong.

Worthless link.
It's not a Ghia gearbox.
The code is not AO, it is A0 (A zero)

Are you assuming it is from after 1965?

Is it a split case or a tunnel transmission? How about some pictures? |

This matter was never really settled. Hate to throw a wrench in this thread but I thought I'd offer something that seems to fly in the face of all comments (and I do so mainly because it's interesting).
I recently had an e-mail exchange I had with Rick Long:
LONG ENTERPRISES
VW Transaxle Specialist
http://www.longenterprises.com
He seems to be an expert who does nothing but VW trannies. With respect to AO360465 (that's A OH ..., not A zero ...)
He wrote:
| Quote: |
The serial number will only cross reference a chassis number and will not tell you by itself what the year is ... It is a 67 if it has a stock 12 volt starter bushing (not an adaptor busing) and 5 bolt brake drums.
|
With this in mind, since the starter bushing in the bell housing does appear to be stock (no evidence of an adaptor) and the drums are indeed 5-stud, I am given to believe the transaxle is from a '67. |

So in other words, he said your gearbox is NOT a Karmann Ghia A-Oh gearbox.

| I think what he said was simply that it's a swing-arm transaxle from a '67 Beetle. He also opined that the serial number will only cross reference a chassis number and will not tell you by itself what the year is. Along with others, I for the longest time was seeking a "look-up" chart of Beetle transaxles by year as a function of serial number (such as is well established for Beetle VINs and engine numbers). According to Mr. Long, such is not possible. The ID criteria he suggested are simply mechanical, which is good enough for me. |

It does exist for the early cars:

I'm sure it does exist for later cars too, it's just not here on the Samba.

As to my recent post of Jan. 09, 2012, I wrote:

This was something of a brain fart. What I meant to write was:
| Quote: | | He seems to be an expert who does nothing but VW trannies. With respect to A0360465 (that's A zero, not A Oh ...) |
With that in mind, Bruce's 1st comment is now understandable. But (again), I think Mr. Long was simply opining as I suggested. Then Bruce comes back and contends that such a "look-up" chart that would allow one to decode transaxle IDs "does exist". I would surely like to think so. As has been stated here and on other posts, what has been put out there as "data" on VW tranny IDs in various spots on the Internet are neither accurate, complete, nor reliable.
On that note, I've set about on yet another (what I like to call) side trail to ascertain the existence of such a chart. This may be harder to find than the Holy Grail but I'm gonna try! I have so far made several overtures to Volkswagen in Auburn Hills, Michigan (VW USA) and Wolfsburg, Germany. If/when I am successful, y'all can be sure I'll post it in The Samba. |

So have you found the serial number chart you were looking for? Judging by the massive amount of traffic by VW owners (not to mention transaxle specialists) looking for such a chart my opinion is that such a chart does not exist. But I'm still hopeful that you will find one and share it with us! 
Other options would be to reverse engineer a chart by collecting transmission numbers from owners of original configurations. Some of the guys here have helped me to identify my transaxle that way. |

That's what may have to happen.
Here's what I think about the A-zero gearboxes. When they went past the 9,999,999th gearbox made, instead of calling the next one 10,000,000, they called it A0,000,000

That makes sense but I'm still confused about the letter codes. Some sites list tables of two letter codes which take you through the 70's, LSD, IRS and beyond. From these charts I gather that most of the pre 67 transaxles are considered AA type transaxles, is that correct?
I just acquired a transmission stamped with AA followed by 7 digits (AA 3 25x xxx). Most of the transmission numbers I see posted do not have a two letter code prefixing the serial number. If I ignore the letters on mine that puts the manufacture date somewhere late in 1960. Am I reading the transmission tables correctly? Can you (or anyone) enlighten me on the presence of the 'AA' letter code and why the 'AA' is not mentioned in progressive refinement's tables?
There is also a 'J' stamped separately (and less professionally) in front of and slightly above the AA. I can only venture a guess that this means the transmission was rebuilt by a Volkswagen dealer.
