in my 1964 chlton there is a list of cars and year and their corresponding transmision. i found that other makes are using "turbo hydramatic 400". my question is can i get the same transmisson from another make and year . also does i matter the size of the engine. plz help if you want more info please ask.
Check with your local boneyard, a quick look in the Hollander's Interchange book will tell you which one's will fit your Caddy.
Hollander's Interchange book is an excellent idea...
Look for the t-400 listed under your model or the coup deville. If not, then chances are that it had not yet been placed in your caddy and the tranny mounts are not going to work. If they are, see if it corresponds with your bellhousing pattern. If it does, your in good shape. Remember, most cars with a t-350 will bolt up to a t-400 if it will support the weight.
Theres allways this way if your keen. Measure the length and count the output shaft splines. Then swap all the internals out of the donor case into your caddy case. Disadvantages- lot of work advantages- you get to check the condition of the parts as they go together. A turbo 400 is an easy trans to work on by its design it has clutch packsthat are enclosed, theres no frictions or steels located in the case itself. Just abit of wriggling and jigling and the whole piece just slides together. Just replace the pan gasket and the front and rear seals. I've done this a few times and I'm no auto tranny docter just using a will to get it done and some good common sense and reading a trans mission book and afew basic tools.
