Guest Posted April 18, 2000 Share Posted April 18, 2000 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?

Guest Posted April 19, 2000 Share Posted April 19, 2000 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. Link to comment Share on other sites More sharing options...
Guest Posted April 21, 2000 Share Posted April 21, 2000 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. Link to comment Share on other sites More sharing options...
Guest Posted April 21, 2000 Share Posted April 21, 2000 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!!! Link to comment Share on other sites More sharing options...
D Binger Posted April 21, 2000 Share Posted April 21, 2000 The fire at the Hydromatic plant was in 1953. As a result GM put Dynaflow transmisions in 1953 Oldsmobiles and Powerglydes in some Cadillacs. I think that the early 53's had the Hydromatics in them. <P>Dan Link to comment Share on other sites More sharing options...
Guest Posted April 21, 2000 Share Posted April 21, 2000 <BR> 1953 WAS THE YEAR OF THE FIRE AND SOME "DYNAFLUSH" OLDS AND CADS ,PHIL Link to comment Share on other sites More sharing options...
Guest Posted April 21, 2000 Share Posted April 21, 2000 The fire may have been in 1953 but in the 60's and 70's the nailhead ST400 was used as I have discribed. Link to comment Share on other sites More sharing options...
Rick Hoover Posted April 21, 2000 Share Posted April 21, 2000 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 Link to comment Share on other sites More sharing options...
Guest Posted April 21, 2000 Share Posted April 21, 2000 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. Link to comment Share on other sites More sharing options...
Rick Hoover Posted April 21, 2000 Share Posted April 21, 2000 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 Link to comment Share on other sites More sharing options...
Guest Posted April 21, 2000 Share Posted April 21, 2000 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.

Guest Posted April 21, 2000 Share Posted April 21, 2000 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!

Guest Posted April 22, 2000 Share Posted April 22, 2000 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!

Rick Hoover Posted April 22, 2000 Share Posted April 22, 2000 Mike,<BR>I forgot to take a look into this while at the shop today.<BR>Didn't this Dual Coupler tranny come out in 1959? I think that there was something done differently to it though in 1964. <P>Rick Link to comment Share on other sites More sharing options...
Guest Posted April 22, 2000 Share Posted April 22, 2000 Your getting out of my league here i know the change in 64 was the turbo 400 in some Caddies but i think the 4 speed was around before 59 i `m pretty sure the 58s had them not sure before them, HELP!! <P>------------------<BR>Mike<BR><A HREF="http://1964cadillac.carsouth.com" TARGET=_blank>1964 Cadillac & Classic car Photos<P>FREE!

Guest COMPACTBC Posted April 27, 2000 Share Posted April 27, 2000 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> Link to comment Share on other sites More sharing options...
Guest Posted April 28, 2000 Share Posted April 28, 2000 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? Link to comment Share on other sites More sharing options...
