I have asked about swapping from 3speed to A904 in the past but now have a option to buy a complete 75 valiant with a brand new motor. My question is can I install the rebuilt 225, a904 and the drive shaft out of the 75 valiant in to my 64 valiant? I am also thinking about swapping to the none power assist disk breaks? Thanks Michael |

The '75 trans will not swap into the '64 without a great deal of work, expense, and additional parts. The brakes are a better and more compatible swap. |

Dan I believe you if you say it wont work but with me not seeing this trans yet I am curious as to what about it wont work is it just bigger, longer or completly different all together? Thanks for your help and knowledge. Michael |

During the 1967-68 model year chrysler changed the hub and pocket on the back of the crank to be larger (up to the end of the slants run in 1987).So your scenario is this (assuming stock parts for stock parts): 1968+ engine will work with 1964 tranny (with a spacer to keep the torque convertor snout centered in the crank pocket...so if you keep your tranny and swap in the '75 engine, you need to do this) 1964 engine will not allow the torque convertor snout the fit in the pocket if the torque convertor is from a 68+ Options on the '75 tranny: 1) have a custom torque convertor made the uses the '64 style snout but fits the splines, etc. of the 1968+ tranny 2) replace the crank in your '64 with the one from 1975/ or use a late crank kit 3) pull your 64 crank an have the crank pocket opened up to the correct 1968+ size... Next on the list: You will have to change your driveline, and your pushbutton controls for a column shift unit(which may involve swapping items from a 1966 car into your 64, to make everything work...), you also will have a few other things like the change in neutral safety switch and reverse light electrical you have to reroute as the late tranny uses a different switch setup... There's more, but you get the gist at this point, it can be done, but you have to decide whether you want to hack up your car a bit and/or if you have the time to make all the swap items work correctly... -D.Idiot |

After reading this post over am I right in understanding that all components are to be used from the 75 and that the car is now a 3 speed manual ? If so you will will have to use a aftermarket shifter mounted on the floor. and shorten the driveshaft as the 75 has a 111" wheel base and the 64 is shorter. I'm not sure but I think the 64 is 108". ( don't hold me to it though ) Now that is the cheapest way to go if you just want a driver and not use the push button set up and do a change over to original equipment. Imperial services has a conversion to use push buttons and 66 and newer transmissions. |

You can swap the whole unit from the 75 into the 64 if you dont mind coming up with a shifter and neutral start switch. Thats what I would do. You can leave the clutch pedal as a Dead Pedal....set to your height,,,,nice for long trips. A cool shifter for a 904 is the one from a van....almost infinitely adjustable. |

Yes the car is now a 3 on the tree but I was thinking of just taking the whole drive line engine and tranny from the 75 and dropping it in to the 64 I will probly use a B&M zgate for the shifting anyways. I would just need the drive shaft shortned and bypass the nuetral safety switch deal with that when i get to it. I have read the other posts about the break swap and think I may get the car just for that reason as i understand I would then have to go with the big bolt pattern wheels as well? So could I swap the rear with the big bolt pattern as well? I think they are wider correct. I would like to keep the same bolt pattern all 4 corners. Thanks Michael |

The rear axle out of the 75 should be swapped as well..although it may have gears that are less desirable than the 3.23 you have now. When I did my 75-65 swap i put my 65 3.23 gears n the 75 housing and swappter in. They are the same width. I bought a whole 75 parts car for $200 .......got a lot of stuff....and it all matches. Make sure you get the 75 trans mount. |

The three prong neutural saftey switch on the 75 trans is useable in the 64. The plug from the donor 75 can be reused to rewire the 64. The center wire hooks to the starter relay terminal. If your car has back up lights (optional back then ) that are not working, hook the other two wires to the wires that are on the switch on the steering column at the base of it next to the firewall. |
