1954 Cadillac Dynaflow VS. Hydramatic??

I'm looking to order a water pump for a 54 Cadillac my friend owns, and I noticed it said the pump wouldn't work on cars equipped with a Dyna-flow transmission.

I always thought that the car had a Hydramatic, but this has me wondering.

Did mid 50s Cadillac's only come with Dyna-flow's as the automatic transmission? Or would a Hydramatic be an option as well?

I don't want to order the wrong part.

here's the part http://www.ebay.com/itm/Water-Pump-...its=Make:Cadillac&hash=item2c646e32ad&vxp=mtr

 

There was a fire at the Hydramatic plant that stopped production around then so GM made do with what they had.

 

The amount of funny sarcasm on this board has me cautious, are you being serious? haha..

 

There was a fire at the caddy trans plant so they got olds hydro's for a year is the way ive heard it...

 

Shaggy, if thats the case then why does the ad say "except those with DynaFlow transmission"? I really don't want to order it and have it not work and have to send it back..

Can anybody tell me if the DynaFlow shift pattern is the same as the Hydramatic? I know the Hydramatic is N D Lo R.. from owning a Pontiac with one.

I guess i read it backwards on here....

 

Cadillac Dynaflow
The early 1950s Cadillacs were normally equipped with Hydramatic transmissions. However in 1953 the General Motors Hydramatic Plant burned to the ground, leaving Cadillac without a source of transmissions. Buick Dynaflow transmissions were hastily adapted to Cadillac mount points, and some 19,000 1953 Model 62 Cadillacs, and some 28,000 Cadillacs of all models, were equipped with Dynaflow transmissions. Several thousand 1953 Oldsmobiles were also equipped with Dynaflow.

 

i dont understand what that has to do with the water pump? its a good history lesson, but dont you need a waterpump? they didnt change the block i dont think... just try it!

 

Agree with Boomosby...the 331" water pump has virtually nothing to do with the tranny...it's not connected in any way...about the only difference in some I've seen is where the heater hose ports are...that's it... and that one (e-bay) looks like my brother's '54 Caddy pump, except the heater hose ports can't be seen. $189 is a decent price...USA Parts and McVey's want $200 plus your core and shipping costs.

Thanks for that I had no idea, however am aware of the trans plant fire, always assumed there were other Hydramatic plants, guess not.

 

There was ONE Hydramatic factory in Livonia that served all of G.M. It burned in 1953; cutting off the supply of Hydros for Olds, Cadillac. and Pontiac. Cad substituted Dynaflows, Pontiac sub'd Powerglides, Olds ? G.M. built a new factory in the Willow Run buildings that had housed Ford's WW II B-24 operations and later Kaiser-Frazer assembly.

 

Thanks a lot guys. I was wondering the same thing.. what does the transmission have to do with the water pump?? But since it said it in the ad I thought I would ask.

Thanks again

 

I belive that the two speed Dynafow shift index is P-N-D-L-R as well. Was just looking at one in a Buick Century.

 

Yes, but at least on my Pontiac, it didnt have a Park gear. When the engine was off, you could put it in Reverse to lock it up, otherwise you just had to pull the e-brake

 

Buttin' In, None of My Business..............But,

If You Don't like the Anwser !!!!!!! Take back tha' Question............

I aqired a Four Speed Hydro-Matic, That came outta' a '66 Ford P.U, was behind a Ford 360 Engine !!
On the I.D. Tag hit sez "Build fer Ford Motor Co.....Linc-Merc Div.

Big Smile !!!!!! Same Trans was in Some School Buses ......

Still Smoked-Up, But I do Remember " A Little Bit" Definite Maybe !

 

My 1952 Kaiser had a Hydro in it behind a flathead six and my friend has a flathead V8 Lincoln that runs a early 50's Hydro that is stamped "Hydro built for Lincoln".

 

Dale Fairfax is right.... Some "Ponchos" had p'glides.. A couple of our customers had them. I don't recall the shifter pattern, though.

The early Hydramatic's up to about 1956 or so did not use a transmission oil cooler because the Hydramatic used a fluid clutch with two planetary gear sets to give 4 forward speeds. The Buick Dynaflow used a torque converter and the single planetary gear set it had was only needed for Low, Reverse or Neutral or Park. Normally Drive range was used for all driving. A torque converter generates heat and needs to have a transmission oil cooler. Buick used a small heat exchanger on the side of the transmission that was cooled by heater hoses that ran from the side of the water pump that picked up engine coolant from the bottom (cool portion) of the radiator. When they installed Dynaflow transmissions in 53 and early 54 Cadillacs they had to modify the water pump and hose routing for the oil cooler.

here is the link to the fire

Finally a full answer, now all you have to do is see what the heater hoses do to confirm the needed purchace.
