Ford C6 Teardown

[@mikeydrake4894]

Back around 1995ish I had an old 69 Ford LTD. 429 2 door. Cool old beater. Living in the San Diego, CA area. Anyhow the trans was used up. So I went down to the scrap yards to find one. I ended up pulling apart 2 different ones in the yard. Picked and chose the good parts I wanted. Even got a big R servo from a Lincoln. Reassembled it in the yard and went home. Resealed it and ran it for bout 4 years. Good times.... Worked at Valley Trans in El Cajon California then.

[@griffparker3992]

Thank you so much sir for making videos on the C6. You're helping me get through my C6 rebuild for my 67 Galaxie 500. Everything in your videos is that same on my unit. Videos really help, thanks.

[@jurgensduplessis1964]

Me too i love 4 speed automatic transmission or 6 speed but the 3 speed automatic transmission is welcome

[@vioransoldier9868]

Very helpful, I'm taking apart a 1975 C6AP for my transmissions course. The last few minutes of the video are the insight I need to complete the teardown.

Very interesting thanks for making this video. Transmissions are the big mystery in cars for me.

Thank you for great teardown video

[@capriracer351]

C4's and C6's are both simple easy transmissions to work on. For the C6, the front pump is always a little bit difficult to get in and out due to the o-ring around the outside. Also, the reverse servo springs can be a pain to keep aligned while installing them. There is a whole selection of servo piston apply and release sizes as well as a selection of apply levers. Mixing and matching these correctly will greatly improve shift quality. I still have 3 small block (289, 302, 351W/C) case C6's in the garage, but preferred C4's when I was racing.

[@capriracer351]

Also, at 31:45. There were 2 different types of seals. There is a lip type and a flat type. If you use the wrong seal, you will also get a bad delay or the transmission won't move. That was a real problem years ago when people rebuilt their C6's and did not know what they were doing. It has been too long ago, but if I remember correctly, the earlier C6's had the lip type of seal, but the later ones maybe '70 and later did not. Also, people would install the lip type upside down, obviously causing problems.

[@GaryFerraro]

@@capriracer351Yes sir, this trans is very early, no lip seal came in this kit lol.

Hit the lottery on that core!!!!

[@kevinclancy.]

thanks great video. I am tearing down my 1989 C6 from my Bronco, and the spacer ring that sits in the piston in the forward drum was bent and half out- sticking above the bellville washer. it got all jacked up I am still trying to get it apart, retaining ring is stuck

[@GaryFerraro]

can you get the snap ring out that holds the belville return spring in place?

[@kevinclancy.]

Yes, I got the snap ring out. the snap ring that holds the inside part of the ring gear to the outside part was also broken, I found half of it laying on the back side of the piston where the circular cross section spacer ring goes, and another portion of snap ring still in the groove on the ring gear@@GaryFerraro

[@GaryFerraro]

ok, Parts should be available for this trans if your rebuilding it@@kevinclancy.

[@waynep343]

that is from behind a 390, 427, 428FE engine.. that explains the bell housing.. some use a 3 bolt starter mount with 5/16 threads instead of 3/8 threads.. there are significant differences in the manual level external shapes between body styles. that one looks like its for a floor shift.. for those who have never seen one.. this is a 429SCJ C6 converter from a 70 Torino Cobra .. i.imgur.com/gkERCdl.jpg look carefully at the welded straps that hold the studs. way stronger than just welded studs. here is the transmission side.. i.imgur.com/Fk6EUDk.jpg just thought i would share.. hi gary..

Hey Wayne, thanks for the info.

[@Moonless6491]

I've got this in my 1995 F250. It was the last year it was an option and I didn't know it was only a 3 speed when I bought it from a friend. I just thought it needed some work. I hate only having 3 speeds.

[@warerlifetexasranger5349]

At 13:01 can i just pull that thing out without opening the back? All I need to do is install the gasket.

[@GaryFerraro]

Yes, this will come out without pulling anything else apart

[@kascus]

What year did they go from a plastic speedo drive gear to one made into the shaft?

[@GaryFerraro]

I don't even remember these having a plastic gear, maybe in the late 70's

[@EdTrollington]

I need to replace the front pump gasket and seal on my C6. What all needs to be disassmbled to get it out? Can I just pull the pump off or do I have to drop the pan and take other things apart?

[@morrisschwarts4826]

Should be 2 threaded holes where the pump bolts are for a slide hammer, so you don't have to beat the crap out of the pump shaft.

[@GaryFerraro]

I don't think they have that on this trans

[@TheThirdWheel618]

Hi thanks for video I wanted to ask are you familiar with the C6 that has a short 7" tail housing and a square flange yoke with a big nut holding it in ? I have a 69 F250 C6 390 I bought a gear vendor for it although it has the 14" tail adapter , the only options I have is to change the output shaft to the longer 14" shaft . Although I was told that the trans needs to be removed from the truck to do this since there's a c Clip that holds it in . Not sure if this is correct since I have a big nut holding my output shaft on already I was told I have a bearing behind the flanged yoke and the nut holding it together keeps it in. Wanted to know if I can push in the 14" output shaft with out taking out trans since I have the shorter tail housing with the bolt o yoke ....only other option is to buy there shorty gear vendor kit it comes with a out put shaft and they say it will just slide in no need to remove trans to install the the splines of the out put shaft goes into the gear vendor are you familiar with the short tail sqaure flange yoke C6 ?

[@GaryFerraro]

I will ask my manager, i have never seen it without the snapring, let me find out

I have a 81 F100 / straight-6 engine. C6 tranny , The truck runs fine, shifts up ok.. but it does not want to down shift til you're at a dead stop, if i turn a corner it'll still be in 3rd, unless i really step hard on the gas. or I manually down shift it.. Any advice ? already changed the modulator, I can't tell any difference. I even adjusted the screw several times.. Is there anything I can try before taking it to a shop..???

@Gary Ferraro, I've got a C6 from a 74 f250 that had a neutral safety switch in the steering column that I'd like to use in my 78 f250. as the 78's use the safety switch at the linkage/kickdown arm, how complicated would it be to upgrade the switch? it looks like the mount points are there, but I 'd really like to hear from someone like you about this. Thanks!

[@joser5193]

Have a question. What keeps the inner kick down /passing gear lever from falling off? Thanks

[@GaryFerraro]

on the outside there should be a bolt and a washer

[@joser5193]

So there’s a lever that’s bolted to the rod on the outside. Now on the inside there’s a shifter that has a nut that is tighten but another lever attached for the kick-down/passing gear. Unfortunately there is nothing keeping that lever from falling off. Any ideas

thanks for the lovely educational videos Mr Ferraro , been your subscriber for a while now , and I must say your videos I found most detailed in educating the public . on a Note though regarding the Japanese RL4R01A ( known as Jatco automatic ) I own in my 1999 Nissan Frontier L 4 with KA 24 D engine , I found the following from Nissan over Japan themselves the following : they no longer make those type of gate driven , they no longer make parts for them either , and you can only order generic or upgrades . I also found important information from them as follows : for every 70 to 100 thousand miles ? you must reset the PNP switch control cable tube ( located under the Passenger side ) where it's cable mount bracket is , I was informed of the following steps : remove the nut and seating hinge from PNP arm use either #12 wrench or adjustable wrench to open the adjusting tube ( counter clock wise ) till the seal cover is aligned ( it looks like a rubber corrugated form ) and in time ? it twist on it self and that is caused by your shift level from steering column as you use it countless times . then tighten clock wise ( almost 5/8 inch or until you see the corrugated rubber seal is returned to its uniform shape ) , tighten back the seating and the nut and make sure the shift is locking in P , and clicks on all positions , and you good to go . you remember when we had a chat regarding my truck transmission in your RE4R01A video ! i Presume , and she was doing great after I rebuilt it , and last week it started no shifting to 2nd gear , so after extensive research and lucky me I called Nissan in Japan ? I discovered this issue , and saved me tons of Money , cost me nothing but half hour to reset it and she is now driving again like a champ . I just wanted to share this with you and the public interest here as a gesture of thank you for all your priceless times in helping us all . [ edit ] p.s : she have now over 360 k mile on her . and still going like a charm .

Did you disconnect the linkage at the trans to see if you have park or to see how the linkage moves inside the trans?

[@that_dude_with_the_torino1171]

@@GaryFerraro oh jeez. Long story. This video actually ended up giving me the confidence to dig into the transmission myself and I figured out that the shifter I had been messing with, was not the actual shifter. The real shifter had broken off and I wasnt aware. I believe the lever I was working with was the kickdown that I hadn't hooked up. Tore apart the transmission for no reason, but I learned a little bit in the process 😅

The Ford C6 is one of the strongest Automatic transmissions made. This same 3 speed automatic transmission was used in the bigfoot monster truck for a while. Its easy to rebuild and modify from which I heard and there is a book on how to modify these. Also the Ford C6 is linked to the GM-TH400 and the Chrysler TF-727 in strength and performance.
