69 RT HD Transmission D32

[Rudderguy]

Good Day All,

So what did it mean when the D32 option was included as a package on the 69RT with the 727?

What made it "HD" and what was different about the 727?

Hopefully John Kunkel will chime in soon with a definitive answer as the resident 727 Trans expert ?

That said,
my understanding, and I am NOT a 727 Trans expert, is the D32 H.D. Units used 4 pinion planetary's front & rear, and extra clutch plates in the front drum machined deeper to accept ? (5 front ? or was that the deep hemi Box frt drum ?)

As is also my understanding, the 4 pinion Planetary's and deeper Drum(s) are interchangeable into the Non-HD Units.

The D32 simply means the 727 transmission, it's Heavy Duty compared to the smaller 904.

I thought the internal workings were also different in the 727 depending on the Car engine size.

I thought for sure I read that for a....

440...4 clutch discs, 4 steel discs, 6 return springs

440HP...4 clutch discs, 4 steel discs, 10 return springs

426 HEMI...5 clutch discs, 5 steel discs, 12 return springs.

Were internal workings different for these cars or just a myth?

Yes, the guts are different depending on the year/engine but that has nothing to do with the D32 on the fender tag.

IOW, some 727's were more heavy duty than others but that info doesn't appear on the fender tag. The part number stamped on the LH pan rail tells the application.

I've been trying to make sense of the Transmission application numbers listed here:
http://www.mymopar.com/downloads/transguide.pdf

As best I can figure out, the list seems to show for following the Dodge's/Plymouth's in 1969

2892090 69 8-383-2BC Dodge & Plymouth

2892091 69 8-383-4BC Dodge & Plymouth 330 Horsepower (NON 335HP Magnum Engine)

2892092 69 8-440-4BC Dodge & Plymouth

2892093 69 8-440 Dodge & Plymouth and Plymouth 69 8-4BC 335HP (Magnum Engine)

Weird to me, that there does not seem to be a distinction for usage between the 2892092 or 2892093 between 440-4BC 375hp "Magnum" Engine or the std 440-4BC 350 Horse Engine
yet,
the 2892093 seems to be clearly marked for use behind the HP Plymouth 8-383-4BC 335hp Magnum Engine, with the rest of the 1969 8-383-4BC 330 Horse Engines getting the 2892092 ?

All I know is that between my numbers matching 1969 Charger R/T and a friends as well,(small sampling), but BOTH of ours have the 2892093 units ? ... although, according to the list the 2892092 unit could have been used also ?

QUESTION:
Does anyone know if D32 is used on a 1969 Coronet 383-2BC Fender Tag to indicate a 727 Automatic ?
or,
do the Fender Tags for 383-2 Barrel Carb Engines read D34 ?    Obviously D31 being the 904 behind small block 318 and slant 6's.

I am wondering the same myself...what was the difference?

The transmission that I am rebuilding is the 289209"2".  It also has an "L" at the end of the number which I have been unable to determine the meaning for...as posted in another post.

D32 only tells you the "what".....727 transmission.
You have to go to the broadcast sheet, or fender tag on a Lynch Road built car, to tell you the "which" meaning which specific 727 was designed for that application.

You'll find D32 on the fender tag and the last three digits of the assembly (092, 093, etc) on the broadcast sheet.

Yep, that's what mine says, 093 on the B-Sheet and D32 on the Fender Tag.


I am still curious, anybody ever seen a D34 Fender Tag on a 1969 383-2BC W/727 ?
