Question about C6 Transmission
2 Question? I put a 1968 302 Ford motor in my 54 F100 (motor runs great! been redone), anyway I installed a rebuild C6 in it 1st time, it didn't seem to shift into 3rd, so then to make sure, I bought and had a New C6 Trans put in it. 1st question: Even on the new C6, I know it shifts twice just like the rebuilt one did, but I'm not sure if it is shifting into 3rd, because of the headers being to loud I can't hear it, and I can't feel it, but I guess it's possible it's working OK. But when I'm going around 60 and let off the gas it seems to slow down to fast as if I was shifting down. IS THERE A CERTAIN WAY TO HOOK UP THE AIR HOSES TO IT? COULD THAT BE WRONG? I did have an Auto repair place install the New C6, but their not a Transmission specialist.
2nd question: also the passing gear isn't hooked up, so when passing another car it will not kick down in 2nd, that's if it's in 3rd. How do you hook up the passing gear? (I had a 83 Mercury Cougar and on the side of the Carb, the kick down rod fell off and it wouldn't shift into 3rd) could that be the whole problem and if it is, how can I fix it???
Thanks for any help.

Hi Tom and welcome to FTE. A s far as I know there are no air hoses on a C6 are you referring to the vacuum line that goes to the modulator on the passenger side rear of tail housing? The kick down lever is used for a passing gear and mainly used in a full throttle position. Lots of people never hook up the kick down lever at all. There is a discussion going on right now on the Transmission forum about the kick down rod and its use. Just go to the top of this page and click on forums and then click on List. Go almost to the bottom of the page and you will see a forum for clutches and transmissions etc.
There will also be a lot of guys on here that will have useful information also. I have a C6 behind a 351W but sad to say its not been ran yet. I do have the kick down rod installed.

why I have a C6 and not C4
It came with a C4, but was so old the transmission shop said they couldn't rebuild it. They had a C6 housing and said they'd rebuild it for me, that how i ended up with a C6. Which I did hear was tougher-but I don't know. Shouldn't you feel or hear it shift into 3rd. I really don't care about the Passing gear (unless I need it). I just don't want to tear it or my motor up and I'm out of money. Money was one reason I got the 68 motor and not a newer one. Which later I must change the points to electronic distributor.
I do have something some Ford fans may want. A complete 1963 '260' V8 (302 is the same except piston size-63 is 3" not 3 1/2" but gaskets are same) it has never been started nor in a car and just needs Carb, distributor and starter, it even has the exhaust manifolds. comes with a nonworking 63 trans out of a 63 Galaxy that does need rebuild.
Thanks for info. Tom

Now, I have to say, if your engine noise is so loud you can't hear the transmission, you need a bigger amp on your stereo.

The Header on the 54
I bought these headers for the 302 from Jegs, Drivers side fits great, but i sent the passenger sides back because it turned into the trans hitting it very bad, the replacement wasn't much better, so i cut it and welded it up and now it just does miss the trans, Kinda wish I went with regular exhaust manifolds and it be quieter and I could hear problems better. and I'm sure it has some leaks, not done with exhaust, but drove it a couple times about 5 miles each way.

Yes, I mean the modulator, the Trans shop told me to add a (round cylinder with a hole on each side-one goes to trans and other to vacuum on motor--can't remember the name of it). and that it would shift into third better. But i had the auto shop check the vacuum on motor to trans and they said it was good and that i didn't need the round thing. I can tell really easy when it shift. Something just hit me-like a light went off! Question is: DOES A 3 SPEED TRANS ONLY SHIFT TWICE? Like a standard starts off in 1st, then shift at about 10-15mph into 2nd, then at about 20-25mpr into 3rd?If it does, then it works ok and I'm just getting older and forgetting half the things I remembered or just I'm stupid! I have rebuilt a standard trans when I was younger, but don't know anything about an automatic except how to bolt one in and now my health won't let me do that anymore. Thanks you very much!

DOES A 3 SPEED TRANS ONLY SHIFT TWICE?
Welcome to the forum Tom. First off, if you are actually going 60 mph in 2nd gear, your engine would be turning about 9000 rpm, (or at least sound like it) depending on your rear gear ratio, so I doubt that is your problem. Second gear ratio in your trans is in the ballpark of 1.9 to 1. That means the engine would be turning nearly twice as fast in 2nd as it will in 3rd.
Now, I have to say, if your engine noise is so loud you can't hear the transmission, you need a bigger amp on your stereo.

Yes, 3 speeds auto or manual only shift twice. Does it shift early with light throttle but hold the gear long with heavy throttle? I would put the kickdown linkage on it anyway, as that will quicken the response if you do suddenly need a big dose of loud pedal.

the C6 shifts as u mention 10-15 1->2, and 20-25 2->3.
I have a C6 behind my 460. We had valve body problems, and initially
have no 3rd gear. We replaced the valve body, and got 3rd, but list second.. and a final valve body got all three.. seems the case and valve body have some interdependency..

It came with a C4, but was so old the transmission shop said they couldn't rebuild it.
That being said, you will want to hook up the vacuum line to the modulator. It, in conjunction with the governor, helps the trans to shift at the right point and holds the lower gear longer under load to avoid lugging the motor. You are correct, 3 speed transmissions only shift twice because they start off in first gear.
The kick-down lever can be replaced with a cable from Lokar. They come with good instructions and are easy to install. I used one on my 289 and C-4 when I couldn't find a rod and bell crank assembly for a decent price.
I even called DVAP (yeah the guys from the TV show) and they wanted $250 for the kick-down assembly. I guess the TV show went to their heads. Either that or they think I'm from Europe.

Really? Too old? Was the case broken? I think they just didn't want to work on it. The C-4 was introduced in 1964 and built until 1968 (according to wikipedia) and I just had a 1964 C-4 rebuilt here in Moore, OK. Total price with upgrades to hold the HP my modified 289 will put out and a custom torque converter built to match the cam specs was $900.

When I originally started my 52 project a friend of mine gave me a 351C with the matching C4 from an early 70's Ranchero. They also came in Torino's and probably some station wagons. That was a false start to my project & I ended up giving it to another guy. On the second attempt at my project I ended up witht he 351W and a C6 out of an F150.
The point being...the C4's were made for quite a while & there are still plenty of them out there. I understand that Ford had the kinks worked out of them for the 70's and they are more-or-less sought after by drag racers.
