I'm 16, and have a basic grasp and understanding about how my truck runs and what does what, But, My transmission is startin to slip, and i wanna rebuild it. Any Pointers?? I have a 1972 F250 Camper Special With a 390 and automatic C6.




Thanks in advance,

Jace

 

It is doable, but I would suggest that you might want to get someone with some real knowledge of automatics before you go jumping into it.

Lots of channels, little steel ***** and springs that need to be in the right place for everything to work. It is alot of work to get it back in the truck to find out it just sits there when in gear!!

Now, I'm not saying you can't do it, but get one of the "how to" books and do some reading first.

 

1st of all Welcome to FTE.
2nd, I think it's awesome at the age of 16 you have the gumshin' to want to take on something so major and heavy.

And 3rd, Google it. I am sure there are videos and such on how to do it.

Good Job Dude!

 

Freightrain, Do you honestly got one of them how to books and REALLY looked it over, me and my dad could tackle the project? my Dad's been workin on these old trucks since he was 13, just dont know awhole lot bout trnsmission, and i know nothing hardly.


Thanks JEFFFAFA, Haha, What bout you? Thinkin its doable?

 

Take lots of pictures of the internal parts as you're taking it apart if you decide to do it.

 

Yep. I got faith in you and your Dad. You sound like I was at 16. As I said check out Google. I'm sure there will be some special tools needed. Like snap ring pliers etc. Which I am sure a You Tube video will tell you. Note,
I remember way back in the day I worked back (shop) counter at a different Ford dealer than now. There was an old German dude that put vaseline jelly on the internal o-rings and seals. He never had a Come-Back.

 

This is a good manual. Step by step photo instructions.

Another good one:

One more to consider:

It wouldn't be a bad idea to get all three and read them. What one doesn't cover, another probably will. Get a good micrometer and calipers and learn to use them. Shims, bearings, etc. may look identical but may be a bit different in size. Get a box of Ziploc type sandwich baggies and put all your removed small parts in a bag depending on where you took the part out of the tranny from. Take lots of photos, notes, diagrams, etc, along with measurements of small parts removed. This job is doable, but not for the faint of heart.

 

Big Thanks to all of yall. Cant tell you how much i appreciate all yalls immediate and serious attention in replying to this. I'm gonna read up on these and see if i cant talk the old man into it! Haha

Thanks again guys. Seriously appreciated!

 

IMO, the C6 is complicated, to say the least, especially if someone has never overhauled one before.

 

The C6 master overhaul kit comes with a very detailed & complete instruction manual. If ya can build a model car and follow instructions anyone can over haul a C6. Yes there are a few things to know that can help. Like stack the clutch packs in a coffee can with proper type trans fluid and let them suck up all the ATF they can hold for at least over night. A few days is okay but be ready to install them and don't let them dry out before filling and using the tranny. This is one reason I am cautious of buying an off the shelf tranny. How long has it been on the shelf. Ya sure it will work with them dry but they will wear out faster. And pre lube everything. I use White lithium pre lube from Napa. (Not on clutch packs) AND after a hundred or so miles change the fluid and filter.
