I need to retract my previous post, as the U code 440 HP engines only had 4 clutch discs from the factory. Only V code 440-6 engines and hemis got the 5 clutch packs. I learned that the ring grove in the input shaft for the U code engines signifies a hardened input shaft, and not the 5 clutch disc packs. I researched all the service manuals from 1969 - 1973 to sort all this out. What still confuses me is what D32 vs D34 means for the transmission code? For example, my C bodies with the U code engine have D32 trans codes while my B body 73 Dodge Crestwood wagon has a D34 trans code, but it has the 400-2 bbl engine? And then it also looks like all C body transmissions had large 11 3/4" torque converters, even the V code engines, but B bodies had 10 3/4" converters with the HP engines. All a giant mess.

In any case, all 383-2 or 400-2 bbl engines had 3 discs in their clutches, while the 383-4 and 400-4 and 440 std T code and HP U (4 bbl) code engines had 4 discs and the 440 V (6 bbl) code engines and Hemis had 5 clutch discs.

In the book D32 is the 727 and D34 is standard automatic.

This is the questionable part...... All hemi auto's had the 5 clutch packs and only SOME of the 6bbl auto's came with the 5 clutch pack's.
It may be that the V code 6bbl's got them in 70-71, but the 69 A12 "M" code w/auto used a four clutch pack trans.

Reference 1969 parts book......

69 R-W w/383-440 HP & C, (P&D), w/440 HP, except wagons. part # 2892093

69 R-W w/426. part #2892094, (service parts discontinued). Superseded part # 3410671

I don't have a 70-71 parts book.....

I should have included a caveat with my response as well, as my 1969 and 1970 service manuals are for Chrysler & Imperial only, so neither of them comprehend a V code or Hemi engine, so I really can't say about those years for sure except for Chrysler and Imperial. However, I do have Plymouth, Chrysler and Imperial combined service manuals for 1971 through 1973, and they do comprehend those HP engines. So my statement about the V code and Hemi engines in my latest post is believed to be accurate for 1971 and later, as those are the only two HP engines to have the large transmission clutch retainer, which is very hard to find, and expensive as well if you find one. I do believe that 1970 was the same as 1971 though, since my 1970 440-6 Cuda had the larger clutch retainer whereas my U code 1970 engines do not. I have no clue really about 1969 though.

Yes Matt, I saw that too in the code sheet listing I have, plus a D30 code that just says Torqueflite Auto. I am guessing a D34 has 3 clutch discs and the HD has 4 clutch discs probably. I would have thought my wagon would have had the heavy duty version, but because it is a smogged 400-2 bbl, they went with 3 discs I guess. My 1969 Monaco, though, with a 383-2 bbl engine has a D32 transmission, probably because it had some power back then.

I just dismantled the 727 out of my '71 383 4 bbl Challenger and both clutch packs have 4 discs. if my memory serves me it's got D32 on the tag but I'll verify tomorrow. Could the D34 be a 904?

I believe the regular light duty 904 is code D31 based on the code translation information that I have.

It seems that the D32 means heavy duty 4 clutch disc 727 transmission.

Similarly, the D34 is the standard duty 3 clutch disc 727 transmission

Thus, I believe you will find your Challenger will indeed have the D32 transmission code.

All this is speculation on my part based on looking at a lot of information over the last couple days. It could be wrong. Maybe someone has a better take than me.

I would like to know what code the V code and Hemi transmissions have on their body code plate?

My 69 904 is D31. D34 is listed as a std duty auto A/trans.

it doesn't help.
V-code and Hemi cars do have D32, too

I do have all of the Mopar pubs and parts manuals from 1969-1971... original paper in the binders...... I will have to dig further.....
