Ok

Riddle me this...

Housing #1
64 coded tail housing. But takes what is a 65 rear seal.

Housing #2
The other... I have to hunt down the part number, no date code, takes the 64 rear seal.


Housing #1 is, overall, 1 inch longer ...

@lkopaska

Putting out the bat signal AGAIN

Ok... more research done ...so changed this up

Thanks for the thought.

Pulled out the 64 Chryco and MOPAR parts catalogs

Appears that the part number for the flange differs between the V8 and the Slant 6 models... but only starting mid model when the 273 arrived...

273 extension and trunnion flange change

Output shaft part number changes as well, but no specs on what changed.

:wtf:


:lol:

Never a dull moment

It's all Mid year change when they introduced the 273.

Added bearing in the tailshaft

Increased tail housing length about 1"

Changed machining on the output shaft

Changed casting of the trunnion flange.

Can't mix and match early and late model year in this instance

Drove a hour to drop my block at the machinist.... Probably won't get it back til jut before winter... but least the 318 is usable til then :) Spent 4 hours with my sister that went with me... had fun.. no fight or crying so it was a good day :)
 
Send it to me I will weld it up for ya.

And if you don't want to.. send it to him and i'll take it for a spare :) Every time i see a trans for sale it's missing that cover.... guys don't know how to get the cable out so they just unbolt the cover and trash it
 
Hows the trans coming btw? did you get thinner clutches so you can fit more in the drums? 1 extra disc is a lot more clamping force....

The sleuthing and research has taken some time.

There ain't JACK standard on these transitional years, then add the mid-year introduction of the V8 which led to all sort of shenanigans and changes.

Output shaft machining changed (tapered sooner to accommodate the bearing)
Tailshaft casting changed length
Output shaft bearing was introduced to replace the copper bushing in the tailshaft
Trunnion flange changed

It is ready to go back together. I'm happy with how things went. I'm hyper careful so that makes everything take longer. I did find thrust washers out of spec, missing springs and some broken rings on the accumulator and kick down servo, so things should be super tight to start out.

Also, found that the front pump on the /6 transmission had been beat up. Pretty sure you realize, but the early 904 pumps don't have the tapped holes to pull them neatly with a slide hammer, so you have to get in behind it and tap it loose. Someone went a bit nuts so it had a bunch of gouges and cuts.

Way smarter on all this than when I started.

I'm thinking about kinda gathering an early A pushbutton addendum to Tom Hand's book. I took notes on the things that were different as I was going along.
 
Proud papa moment. When your son hits 10/10 at 50 yards with a 22. Then backs it up with another 10/10

Yeah..nfo bout pushbutton trans isn't fun to get.. and less and less guys know bout them... DVW on fbbo is the man if you ever have a question... he know every bit bout them.

And transition years are a mess.. my '62 is a veyr early build.. which uses a 61 K-frame/transmount setup.. which are 100% different then normal 62+....

Yeah, and then there was 64/65 with mismatched stuff too
