I need some expert advice identifying the tag on a powerflite I picked up to rebuild. Looks like a rebuilders Id tag riveted on the side. Anyone ever seen one like this?

I was told this transmission and 318 poly was removed from a 58 Plymouth. It did have cooling lines on it. I have not tore into it yet. I see there are 2 kits available so i know I'll need to tear it down to determine what kit to order. I was just supprized to find a tag where I expected to see the serial number

There are no "1949 250" parts or assemblies listed in the 55-58, 59 or 60 Mopar Parts catalogue pdfs that I downloaded from MyMopar.com.

Good luck.

It couldn't be a factory replacement unit, could it? Once I get the transmission separated from the engine and over to my tear down table, I think I'll grind off the rivets and see if there is any numbers under the tag.

Just checked 1949250 in the 1950-65 Mopar Mechanical and Body Interchange Manual and nothing. Only one hit on 19492 (as 1949277) and therefore nothing for 1949250.

Curious as to why you would put money into rebuilding the Powerflite when a Torqueflite was available in the year of your car?

(In my opinion, easily ignored).

This is for my 56 royal. A powerflite is what is in it now so it'd be an easy swap to replace it with a fresh powerflite instead of all the additional work needed to install a torqueflite

Well I took the tag off and to my surprise the numbers are just a few numbers off! Any ideas

No 1949 253 either.

Well I went to swap transmissions after rebuilding the spare and learned a few differences I didn't know existed with powerflite transmissions. First I noticed the driveshaft flange bolt pattern was different. I did know there was a small and a large pattern. No problem I thought, I'll just swap brake hubs. Then I discovered the output splines come in different spline counts....well that won't work....As I'm studying the situation, I noticed the tail housing is about 3 inches longer on the transmission I built....guess I'll tear them both apart and swap output shafts and tail housings. Any reason this idea shouldn't work?

There were three different sizes of front ball and trunion front universal joint housings: 3.75", 4" and 4.25" (or by another source (an eBay advert), "the flange sizes were 3 5/8"...4"...4 3/8".

As for the output shaft, all I can tell you is my 56 Dodge Powerflite has the coarser/fewer splines version:

I finally got the powerflite back together, installed and it works great. I ended up having to swap out everything from the sun gear assy back in order to get the shorter output shaft to work. Turns out the planetary gear housings is aluminum and thicker on the latter transmission. Using the early steel housing planetaries required the early shims/thrust plates. I also noticed the latter transmission uses a o-ring to seal the throttle pressure shaft to the case. The early transmission uses a seal.

Consider the positive side, you are now a Powerflite expert.

Very impressive! I think you may have talked me out of tackling my 55 powerflite, works ok but leaks like a sieve.

Certainly not my intention to discourage anyone. Just the opposite, hoping to help.
It's not difficult to address leaks. I did this to the original transmission the first go around. That's when I discovered the worn front pump that lead to me finding a replacement transmission. BTW, it didn't leak a drop afterwards.
If you are going to rebuild your existing transmission, unless hard parts are hurt, you won't have any of the mix match problems I had. And it's a fairly simple transmission. Good luck!
