Ford C4 Transmission Overhaul - Reassembly
HTML-код
- Опубликовано: 10 сен 2024
- Well, we have replaced all the worn and suspect parts in the transmission including all steel and friction clutch plates, the intermediate band, the sprag clutch rollers and springs, the govenor and front pump rings, the front pump gear set, all thrust washers and the modulator valve. We have also replaced all rubber seals for the servo pistons, as well as the forward clutch and reverse/high clutch pistons, as well as the shuttle valves inside the valve body. The torque converter required replacement on account of water damage from storage and the input shaft was missing, so a suitable replacement was sourced. There was considerable evidence that the transmission had been meddled with in the past, with some satisfactory repairs, as well as some less than desirable ones. The absence of a valve body gasket, a rock hard forward clutch inner o ring which broke in a few places on removal and the piece de resistance; a broken spring retainer on the line coasting boost valve, which had metal fragments broken off from where the retainer had been forced in (presumably with a hammer). The spring was half poking out as well. I couldn't remember what the end play was during the video, but I'd written it down at the time of checking and it was 1.68mm!
Anyway, this is a long video at an hour, so I hope you enjoy!
The amount of parts you need to keep track of is staggering!
By no means overhauling an automatic transmission is an easy task!
You've got very good knowledge and skill of a typical specialist mechanic for sure!
Been patiently waiting for the next episode. Can’t wait to sit down tonight and watch your part of your projects.
Thanks for the great rebuild videos on the C4 transmission Peter.
You couldn't have posted them at a better time as I'm about to rebuild a pan fill for an upcoming project.

Awesome Dale, thanks for the comment!
Great video. Thanks. Just found you today. Im getting ready to jump into 67 C-4 that wont go into park. Never been inside one. Grateful for your video and any other bits you might send my way.
Another great video. Thanks. I understood more of that than I thought I would. But nowhere enough to do it myself.
You can do it mate!
Wow this brings back memories for me, all bad though😂😂😂
I was apprentice fixing this junk and unfortunately I was good at it then progressed to the BTR 4 speeds, 22 years later I’ve never done it again…..
Luckily I’ve forgotten most of it too…..
Good luck Peter….
I love this junk though haha... I'm not very experienced, but have had some success with these transmissions. I remember doing a recall on the 85LE 4 speeds they used in the later EA's... the valve bodies were full of swarf! Cheers
Great upload, Pete.
Many thanks!
People are scared of automatic transmissions……..I can understand why haha. As always very insightful and informative
Nah, they're only scary if you refit them and they don't work haha, cheers.
So informative. Thanks so much.
Glad it was helpful!
Very informative Peter. 👍
Thanks 👍
Another very informative episode thanks Peter well worth waiting for if only we could still repair our daily drives
That 3 tang washer you had left over is for the front of the rear planet. Yours is an early uses the thinner washer which you fitted correct, as rear planet has the raised edge. Later are flat and use that spare washer you have
I just learnt something, thanks!
Thanks for the video Peter. I was looking forward to it.
Love the long videos too by the way.
All the issues you found in it, I wonder how it performed during it's last tenure in a car.
I also wonder by having no gasket in the valve body plate how this would've affected its operation.
Man, it was built by Dodgy Bros Inc I reckon.
Now it's got the Peter Anderson stamp of approval !
Great work Pete.
Can I ask who your parts supplier was ?
You lost me after the first bit not your fault magnificent teachings as usual
What sort of horsepower can this handle
Not too sure, but around 300 I'd assume, cheers and thanks!
Great video mate 👍 ive only played with Alison transmissions but im keen now to have a go at pulling our t350 apart from the brougham
You're a better mechanic than I am mate, a T350 will be simple for you, cheers and take care!
@@PeterAndersons haha mate we all have different strengths and skills which i love this youtube mates cause we learn something every day
This just serves to remind me that I could never restore an entire classic car myself.
You absolutely could, you're pensive and intelligent... you'd probably show us all up! Cheers.
Pan fill is definitely c10 and case fill are c4 and c9 , another one to tell them apart is c10 the bell housing bolts to the case and the c4 and c9 the bell housing bolts up with the pump 😉
As far as l know it’s an Aussie thing… it’s an American transmission and all the literature refers to both models as C4 case and pan filled… whatever the case all good
yeh c4 and c10 are basicly the same, it is an ozzy thing, C6 is the big box
you are supposed to use vasoline, not grease
Snow white petroleum jelly is preferable to vaseline, as it doesn't have unnecessary additives. The grease I used is purpose made for automatic transmissions, cheers.
