'64 Caddy with a 2 speed tranny???


Guest

Recommended Posts

I have a '64 Caddy Coupe that has a stock 429, but the transmission is a 2-speed automatic. The transmission also appears stock -- it doesn't look like the drivetrain was ever taken apart. But I can't find any reference to 2-speed Caddies made during the '60s.<P>Has anyone else run across a 2-speed '64 Caddy? Is it possible that the factory installed this tranny?

I think you have a TH400, or as Buick called it a ST400. It really is a three speed. ON a Buick if you pulled it down into low then back up to drive then back down it would go into the mystery low gear.

If I remember correctly at one time early on there was a fire at the hydromatic plant and they could not provide hydromatic trans for a while and during this time both the Buick and Cad had Power Glides (2 speed) from Chev factory installed. You might want to check on this.

I don't know about the fire but Buzz is very right, some Cads had the Buick tranny! The Buick nailhead tranny is easily adaptable because of it's very short bell housing area. The converter sets in the rear of the block, so the bell housing is smaller. These Buick nailhead ST400 trannys have been used in many other cars including 60's and 70's Rolls Royces and Ferraris!!!

David,<P>Could you or have you check the ID tag on this transmission? I am only aware of two transmisions used by Cadillac in 1964. One is the GM Turbo Hydro-matic code CD and the 4 speed Dual Coupling Hydra-matic code C unless you had a 75 series and that would be code CA. <BR>You don't state if you have a problem or not.<BR>Check your tag and I'll help you the best I can. Cadillac did some different things in '64. Let me know.<P>Rick

Hey Rick, what is the 4 speed Dual coupling tranny you mentioned? I am not familiar with the Cad series are these for the Limos? Just wondering.

To the best of my memory, Cadillac used the GM Turbo Hydro-Matic ( or as you stated, same as the Buick Super Turbine 400 ) in some or maybe all 1964 series 60, 63 and convertibles. All other Cadillacs used the 4 speed Dual Coupling Hydro-Matic as so did some Oldsmobiles and Pontiacs. I'd have to go pull up some fact sheets at the shop before placing any bets on this as these are hitting on modern years for me.<P>Rick

Some of us old buzzards who were buying new cars in 1953 when the Hydramatic plant burned may recall that Cadillac and Oldsmobile utilized the Dynaflow trans after the fire and Pontiac used Power Glide. I could be partially wrong about Olds as they may have used some Power Glide units. Of course Chevrolet and Buick were unaffectedad as they both had their own transmission.

If you have the 4 speed the indicater will say p n .(2 drives). L R <BR>The dot next to N is for normal driving and as far as I know there was never a 2 speed maybe i`m wrong i`ll check.<P>------------------<BR>Mike<BR><A HREF="http://1964cadillac.carsouth.com" TARGET=_blank>1964 Cadillac & Classic car Photos<P>FREE!

Well I did some checking on the Cadillac Mailing list,<BR> <A HREF="http://www.egroups.com/group/thecml/" TARGET=_blank>http://www.egroups.com/group/thecml/</A> <P> and and the on line 63 & 64 Cadillac comunity <A HREF="http://communities.msn.com/196364CadillacCommunity&naventryid=106" TARGET=_blank>http://communities.msn.com/196364CadillacCommunity&naventryid=106</A> <BR>and no one has ever heard of a 2 speed Caddy in 64. The way these 4 speeds shift it may be mistaken for one.<BR>Somtimes from low to 2 you can`t feel at all,2 to 3 you always feel and 3 to 4 you really can`t feel.<P>------------------<BR>Mike<BR><A HREF="http://1964cadillac.carsouth.com" TARGET=_blank>1964 Cadillac & Classic car Photos<P>FREE!

If in fact it turns out that you have a 1964 turbo 400 Buick trans in your Cad it is not a 2 speed even though you may have only "L" (Low)and "D"(drive)on your selection detents for the shifter, the trans is actually a 3 speed and will shift from low to 2nd to 3rd from the drive position when you start up. Buick did not offer a "L","2nd","Drive" on the shifter until 1965.<P>------------------<BR>

Great Topic, I am trying to help find a fly wheel for a 64 and when she told me it was a two speed trans, I was confused, but am no more. Would the fly wheel be interchangable with the different trans? Any good leads on where to find one?

I have a cadillac posting board on my website your welcome to use. There is also a couple of Internet Cadillac clubs listed that are more than helpful <P>------------------<BR>Mike<BR><A HREF="http://1964cadillac.carsouth.com" TARGET=_blank>1964 Cadillac & Classic car Photos<P>FREE!
