Hey Everyone,
I am new to this forum and could use some guidance. I have a 1927 Chrysler Roadster with a Hemi and Torqueflite from a 1956 Imperial (From what I can tell). I have not had the car long and the day I got it home it would not go into reverse and puked transmission fluid from the front of the transmission. It would go into drive. Of course none of this happened when I looked at it before buying it and trailering it home.
So this weekend, I finally got around to pulling the transmission out. The converter seal did not look that bad and converter did not appear to have any cracks. So I pulled the pan and that is where things got interesting. The fluid seemed pretty clean with no water in it, but there were quite a few rust pieces in the pan along with sealant flakes. Things got worse after that, but I will let the pictures speak for themselves.

My questions are:
With the welded repair on the case, is it even worth rebuilding?
Where can I find another case or transmission in NC?
Where would all of the moisture come from? (I will check the transmission cooler ports in the radiator)
Does the reaction shaft look bad? Or is this just normal wear?

Is this an air cooled unit or a radiator cooled unit?

That's a pity!

With the welded repair on the case, is it even worth rebuilding?

; the shaft for the band servos goes through the center support and my guess is that it will hold - I would carefully grind off any eventual sharp edges. I have never seen this type of damage Before - the shaft for the band servos must bend before this can happen.

Where can I find another case or transmission in NC?

; No idea, I'm in Sweden...

Where would all of the moisture come from? (I will check the transmission cooler ports in the radiator)


; most probably the radiator leaked water into the transmission fluid cooler, perhaps "fixed" with radiator sealant - the transmission needs to be demounted and cleaned.

Does the reaction shaft look bad? Or is this just normal wear?


; looks like normal wear, it would be better if you could find one with no spline damages

I have several CI T/flites here.
Be glad to ship you one.
Will probably be pricy though.
Fastenal would probably be the best bet for shipping something that heavy.
If I can be of any help, just hollar.
I can ask on the 300 Club list server if anyone in the NC area does that kind of work, we have many members down that way.

It is a radiator cooled unit. My next step is to pressure test the Transmission lines in the radiator.

I have one of those here still in a 57 Windsor hooked to the engine yet.
Condition unknown, would make a good core I suppose to exchange or rebuild.
Will be removing it soon to cut the frame up for scrap.

In the pics I'm seeing lots of distressing (expensive) stuff, if it were me I'd go looking for another trans.

I have an extra parts cast iron torqueflite, the case is in good condition. I'm located in Tennessee. I sent you a PM.

Save yourself a lot of time, money and headaches, after all your car is a hot rod.

The CI torqueflite is unreliable, expensive for parts, and most shops won't touch them.

Pull it out and sell it for parts, then buy a GM 700r4, an adapter from Hot Heads, a cool shifter from Lokar, and send your driveshaft in to have a different yoke put on it.

You'll have less money into it than rebuilding the torqueflite, you'll have the reliability of a modern transmission and an overdrive gear, which is probably needed given how small the fuel tank is on most 1927 Chryslers.

It's cool that your Chrysler has a Chrysler engine but most street rodders I know, won't fault a guy for putting in a modern transmission.

I hate to agree, but MoreFin is right. It will be cheaper in the long run to adapt a modern overdrive trans to that engine than to rebuild the old TorqueFlite. If you want to keep it all Chrysler, look for a 46RH TF.

By the way, if it came from a 1956 Imperial, it was definitely liquid cooled. The trans fluid when to a small heat exchanger that was bolted to the water pump housing in place of a lower radiator hose. If you have a metal housing on the lower driver side of your water pump, check to see if it has two pipe plugs in it. If so, it most likely rotted through internally at some point and allowed some water and antifreeze into your trans.

Thank you everyone for your replies. Although it may be easier to swap the transmission for a modern overdrive, I do plan an sticking with a CI Torqueflite. (To me a roadster with a pushbutton transmission is just cool). I do have a couple of questions:
1. what do I need to lookout for when interchanging different years? I believe that if I use my bellhousing and converter, any years (that are radiator cooled) will work.
2. What about the cable? I read that there may have been some changes.
3. Pump, Valve body?

Thanks again,
Brandon

The cable will be an issue, the '56 used a slide cable adjuster at the trans end, around '59 they changed to an adjuster wheel. A later cable should work with your PB shifter.

Could the shift lever/housing be swapped?

No, the 59 and up cast iron hogs had a different casting.


You could get a 59 > cast iron TF and take the best parts out of the two

I still have this transmission available from the 57 Windsor.
Would be glad to band it to a pallet and get it to you via Fastenal.

Don Verity in RI is a master at fixing these. He has people from all over send them in for rebuilding. His rates are very fair. He may even have one he can sell you finished.
