1969 727 w/o vin numbers

[charge69]

Hi everyone,  just for information purposes I will tell you that my 1969 Charger R/T HEMI , which is, otherwise, a numbers-matching car came with the transmisson boss where the vin would be stamped un-machined flat and no numbers stamped there! The other side has the appropriate "TK" number there which is for a 1969 Dodge or Plymouth HEMI and Torque Converter numbers indicating it has a 2700rpm stall speed converter.

When we split the engine/transmission it certainly appeared it had never been split before and everything looked "factory". I am sure it is "numbers-matching" but, no vin on the transmission makes me a little sad! I guess when they assembled the car (3/14/69) and found the unmachined boss for the numbers, they did not bother to try to put the numbers there. With Mother MOPAR , you just never know!

from what I understand, not ALL '69 transmissions had the VIN stamped on them.  So, it very well can be the matching trans for your car.  There is no REAL way to know, but tearing it down may have an indication (and this is a stretch as internals could easily have been swapped).  The hemi has a specific front drum and band.  The governor was a specific RPM governor, but there is no REAL way (at least to my knowledge) to tell the difference from viewing it, unless you buy a governor brand new to compare the size and weight of the governor and spring.

Check your tailhousing on the transmission.  There should be 12 boxes towards the rear seal.  If you find a "dot" in a box, count the total number of boxes that have dots in them.  Each box represents a month of the year.  A dot in each block counts towards the month in which it was cast.  I.E. if you see 6 dots, the housing was cast in June, 11 dots, November.  The assemble date of the car being March should not have a housing in it (in most cases) any later than february.  In other words, the total number of dots you should have on the tailshaft housing should be in between 11, 12, 1, and 2.

Thanks for the info. and I will check the tailshaft when I get to my friend's place where it is being stored. Obviously haven't torn it down yet but everything encountered looks like it is original and correct. Torque converter looks correct.

I bought this car way back in 1976 from a friend of my brother and he swore it was all original except for normal maintenance parts and the engine certainly is. Carbs even still have the blue tags on them!

I drove it for about 4 years before putting it up to save it and the torque converter and tranny was like I expected with a 2700rpm stall speed. It would lay down a 10ft. patch of rubber on a hot asphalt road shifting from 2nd to 3rd at about 80mph in drive.

Thanks again for the info and I will post what we find.

I'd say it's more likely a "parts room" replacement, these would have the correct PK part number but wouldn't have a VIN stamped.  The first set of digits following the part number is the build date, compare that to the car's build date.

The trans could have been replaced under warranty long ago or the original trans could have been pirated at the dealer to replace another one needed by the service department and replaced with a new one before delivery. Ask any dealer tech, things like that happen every day.

anything is possible I guess. I will check all the numbers when I can. seems like I remember the next set of numbers being the the torque converter numbers which are 2700 unless it is in the string of numbers included in the part number. There is a third string of numbers at the end of the set that I seem to recall having 4 numbers but I will just have to look again. Might have been "1104" or something like that.

There is no torque converter info stamped in the trans, the first set of 4 digits following the part number is the build date (2700 would be December 18, 1968), the second set of 3 or 4 digits is the sequence number.

Post the entire stamping here for a decode.

I will have to get the entire number tomorrow but that build date would be compatible with my cars build date.

Number should be PK 2892094 xxxx (10000 day date)  xxx(x) (Sequence)

[charge69]

I think I remember the numbers right (Grrrrrrrr!)

PK 2892094L  2700  1038
Wrote it down and promptly lost them when I got home! The only numbers I am a little unsure of are the last 4 but, I think what I wrote is what is there.

18 Dec 68 is the assembly date (2700) and maxwell is right.. its a hemi case.
