Is there a definitive source out there to help decode a 727 transmission?

Doing research on the forum the "DATE" code just does not make sense to me.

PK37 2534 4213 3005

I'm thinking:


Transmission plant XXXX XXXX XXXX

PK 2534 4213 3005

Kokomo Plant ???? April 23 1973 Daily/sequential build date?
 
Missing number? usually the next seven after PK is the part number designating the year,,,those don't match any trans in my book. For example: PK 3515846 xxxx (1970 383 four barrel after 4/27/70)
 
I was under the impression the last "4" digits were the daily sequential numbers.

Okay, so with using the Chrysler 10,000 Day calendar:

1. Using the "Next to last" 4-digit numbers: 4213 the DATE is: Thursday Feb 8th 1973
2. Using the "Last" 4-digit numbers : 3005 the DATE is: Sunday Oct 19th 1969
 
PK=assembly plant
seven digits=part number
next four calendar date
next four=sequence number per day

15 total numbers.
example: PK 3401663 2905 6299
plant year/eng 10,000 calendar sequence that day
 
PK37*2534 4213 3005 would be from Thursday, Feb 8, 1973. 3005th transmission assembled that day.

A 37***** series PN would be more aligned with the 74-75 model years.

Recheck the numbers. There should be a VIN stamped on transmission to help narrow down the application.
 
That is it!
Cool, thank you monaco66coupe, 69coronetrt and dryheat!
Feb 8, 1973.

This is the trans that came out of the 67 GTX
I dropped it off at a Bud's place for re-build.

Too bad you can't find a 67' Transmission. I recommend a new torque convertor, built by a company that is experienced. The newer Torque convertors/ transmissions have better Internal parts, though.
 
Thanks monaco66coupe,
Yes, this is the 440 that was making a screeching noise on the you tube video that a fellow Forum member posted.
I purchased the car from him.
I believe the 440 is a 73, I'll check today (08 April 2015)
I dropped the 440 off and had the Short block re-built with all new bearings etc.

Cast crank=external balanced torque converter

I'll most likely pick up a 2,000 RPM Stall Hughes or maybe even a cheap Summitt
Engine will be pure torque.
 
A 727 from a '68 B or C-body with a 383-2 assembled May 1, 1968 the 1434th built that day.
 
me next, please! Is it from 1973? Not sure how to tell the application? It's in a 70 cuda 440 now, behind a PK police motor from 1968, so... could be anything I guess...

Can someone help me decode this one: PK 3681052 4136 1076

Would this be from a 1972 340 Cuda

4136 is the build date November 24, 1972 so it's actually a '73 model year. VIN stamped on the bellhousing will tell more.
 
All these questions for decoding and I posted the complete listing of transmissions and their numbers for ya...(#12 post above)
Click and open the pdf and look up the number... its not rocket appliances (Rickyizm from trailer park boys):poke:
