Hey I have a 64 Fairlane 5 bolt 289 with the dual range green dot transmission. The car came with an extra transmission that is clean and I believe has been gone through and rebuilt. Is there anything I need to know before starting to swap transmissions? I assume my original bell housing will bolt to the new one? I have a column shift, and I have Hooker headers. The transmission that's in the car is slipping/flaring pretty bad now and it might be the oppurtune time to get the transmission/torque converter setup I prefer in the car. Might have someone go through it and see if all is well inside, beef up what needs, shift kit,etc. and then do the swap. But I need to know if this is going to be a seamless transition or am I going to run into problems and need other parts. I don't have the transmission here with me atm, and I don't have all the numbers off of it, but on the case near the servo has D50P-7006-AA on the side.
1964 green dot to 1975 pan fill? compatability

Case casting number doesn't tell much, other than it's a 75.
Metal tag on one of the servo cover bolts has trans ID model and what it was installed in.
Assuming the tag is still there.....
Linkages are probably different, both shifter and kickdown.
Pan fill C4 has a different bell housing and that bell will NOT bolt to a case fill trans, and vice versa.
Trans speedo gear is rolled into the output shaft and is not easily changed, you have to change the output shaft if you need a different tooth count.
Torque converters are different, input shaft spline count and size. Bolt/stud pattern may not match your old one.
Valve bodies do not interchange.
Pan fill C4's were often used in light trucks/vans and full size passenger cars.
Trying to "bolt in" a pan fill C4 in place of your early 5 bolt bell unit is a potential can of worms.
Probably better to get your early trans rebuilt, or find a 70 up case fill trans.

Yes, you will need a case fill trans to bolt on your 5 bolt bell.
As long as you get the appropriate converter for the input shaft size of the trans you are installing, then no, it doesn't matter,
Except... if this is a performance application, then obviously the large shaft is stronger.
LOTS of differences throughout the years of C4 production.
early 6cyl versions are different to V8 models, tons of valve body differences.
Later units are considered better.
Ford put this poor thing thru tons of design changes.
73 up V8 units are probably the best from a design and strength stand point.
Beware of the later C5 version, you probably don't want that one. 82 to 86.
Sure...... but I would caution to NOT get anything from TCI
TCI stands for "Total Crap Inside".
I have many story's about TCI units that I have worked on, that I won't go into here.....
That's odd, you'd think a company would choose a better name than Total Crap Inside if they want to sell transmissions. I was looking at some Performance Automatic Transmissions. We'll see what happens. I just put in 4.11 truetrac and now the transmission's on the fritz. Would love to get one good run in to see how good things are. I might try adjusting some bands and whatnot and think about what to replace this with.

Yes I had a bad experience with TCI many years ago. An out of balance TCI C4 torque converter and a "rebuilt" C4 transmission. I ordered a TCI C4 "rebuilt" transmission and was sent a C5 instead. The paperwork that came with the C5 transmission for the "dyno test" was for a C4.
I contacted TCI and was told in so many words to "too bad" as they were not going to do anything. Told me that the Torque converter was not out of balance. My engine was out of balance. The C5 would work for a C4. Could not explain the C4 dyno sheet sent with the C5. I rebuilt my old C4 myself. Made a parts transmission out of the C5. Bought a B and M torque converter. Scrapped the TCI torque converter. My self-rebuilt C4 and new B and M torque converter worked just fine. I would never do any business with TCI again.
