need help to id mopar transmission!!!

Hey guys need some help to id my transmission I just pulled out of a 55 dodge royal. I ran the casting number (2801260-7) which came back as a 727 I think. The car had a 318 in it with this tranny behind it just sitting in there. Torque converter wouldn't bolt up to the 318 and never tried the bellhousing. The tranny has a drum on the tailshaft for the ebrake and the number above the pan is j2829317 4169463 I searched that number and nothing came up... please help! Thanks!

 

picture?

the 28xxxxx number is from the late 60s.

If you post some pictures of the front where it bolts to the block, and the pan near the dipstick, we could see if it's a big block or small block trans, and if it's a 904 or 727.

 

Unfortunately I can't post pics. Would a late 60s car have a torque tube driveline and the ebrake on the tranny?

 

No....that's why posting pictures would be such a big help.

 

It won't be a torque tube drive, Mopar didn't use them. Probably a trunnion style u joint on the E brake hub.

 

There were drum parking brakes used on Mopars in the late 60s, in motorhomes....so it could be a trans out of a motorhome, connected to an early driveshaft.

But it's really hard to see what you have.

 

Early aluminum Torqueflites had that style E brake in the cars too.

 

Have you ever left the park brake on and drove for a bit.. It stinks..

 

had a 50 Dodge with a small rear xmsn gear lube leak.
best way to "clean it up" was to set the ebrake a little and drive 'till the lube burned off.

yes, it did stink.

 

alright finally got the pics!

 

might just be an old Powerflite 2speed...similar to a 2speed powerglide.....very old unit.

 

so do you think its the correct one for my 55 dodge?

 

Your trans is a small-block 727, 1966 or newer.
The hole in the top-front of the case is indicative of transmissions used in vans and motor homes (this is where you would check timing), and the parking brake pretty much says "motor home' since it was never used in any light duty applications.

.

 

big block motorhome trans, like he says. From the casting numbers you provided earlier, it's likely to be from the late 60s-early 70s.

 

What 73 RR said.

 

The only thing is that the 318 flex plate bolt pattern is to small for the torque converter.

 

The flex plate is for a 904.

 

Duh! Lol thanks guys!

 

Ooops! Sorry, guys. The T'Flytes with the driveshaft pincher E brake were cast iron case ones, the car aluminum case transmissions never used them. Trucks and motor homes did, though.

 

Wrong on that, all chryslers from 56-61 have the cast iron trans (no flexplates what-so-ever) but the 62 chrysler has an aluminum 727 trans with the e-brake on the tailshaft.

 

Chrysler had two size flexplates. one fit the torque convertors with the narrow ring gear like your trans has and the other fit the convertors with the wide ring gear, probably what your motor has

 

Why start a new post...
I hope someone can enlighten me on this...?
904 #1 to be identified!

Came out of a valiant station wagon....60 something...
Like this Looked like this one...
He told me it was NOT a pushbutton shift.
It had a two hole filter in it.
There's no pump in the back of it......
I currently don't have the pump in it...Don't know what I did with it..
I might be running the pump in my Dusters 904 right now...(runs great!)

Circle = lines up with second hole in filter...
top.

 

I opened this 1973 318 standard 904 for reference.

Sorry, don't know why the pictures rotate sometimes...sometimes not?

 

25xxxxx part numbers are from around 1966-67, eh? and you might find a casting date code on some of the parts if you look carefullly.

 

How do you identify a double pump 904/727 unit?
Shouldn't it be a second pump in the on the output shaft?

 

Yes. I used to know what year they quit using the rear pump but I forgot.

 

1965 was last year for rear pump and cable shift all though 65s didn't have push buttons.

 

I think there was some federal safety law that required that all shifters follow the same common shift pattern, so the 65s had a normal shifter, but operated by the cable because they didn't have time to do the linkage redesign until the 66 model year. And yeah, that sounds like the right time for them to discontinue the rear pump. I should go look it up, now that I'm back home....but it's pretty soggy out, rain gauge has almost 3" water in it.

 

Still Educating myself...hard to find any pictures / info on these...
(Correction! picture below says "One Piece Aluminum Casing"...Not Steele...Still Learning!)

There's the rear oil pump! (This must be a slant six unit...starter up high!)
It takes the place of the Governor Support...Have to take another look when I get home today.
62-65 NOS front pump (looks the same as post 65 - I think it's the one that's been whining in my Duster for the last 5 years...)

 

yup, they replaced the rear pump with just a governor support. And I made it out to the shop and looked in a couple books, looks like all this stuff changed in 66.
