Hoping someone has a link to a write-up on changing the auto tranny fluid. I googled but came up short. Up to now, I've been cleaning up the underbody to prep for this, but figured it's be nice to see a demo before I tackle it this weekend. Any help or advice would be appreciated. For reference this is for a 360 automatic 72' F250.

Here's vid on how to on a Mustang. The same principles apply:

 

Thanks! So, fill from the transmission dipstick? I didn't look too close, just assumed that there'd be a fill plug?

 

Automatics fill from the dipstick in most cases. Some newer transmissions are different.

Awesome, thank you. Sorry for the questions, but you wouldn't also have a recommended transmission fluid to use or a link to tech specs on fill quantities for my 72? I guess I need to figure out which auto box I have first.

 

You need type F fluid. Regardless of which auto it is.


Pull the pan, dump the fluid, change the filter, pan back on, fill it.

Or you can go more in-depth and flush the cooler lines and whatnot.

 

If you do a good job catching the fluid you can measure it to get a good idea how much fluid to replace it with.

 

If it's the original C6 then you definitely need type-f. Recently rebuilt then Dexron/Mercon will do the trick, which was recommended for my new C6.

 

If you don't have a '72 Ford truck shop manual, you need to get one. It will have all the fill capacities for the various items on your truck as well as other valuable information on how to work on it. --consider the manual as a tool that's just as important as the wrenches, sockets and screwdrivers you use to work on the truck.

The Ford shop manuals can be bought in hard copy form or on CD.

I have the CD version for my '69 F250. I copied each manual to the desktop, then put them all in the same folder. I can print out whatever I need for the job at hand.
If you want printed copies, they have those, too, but be ready to shell out some coin!

 

My 69 owners manual says for a C-4 it takes 20 1/2 pints. The C-6 takes 25 1/2 pints. The HD Cruise-O-Matic takes 22 pints. Don't forget to drain the cooler too!

 

Those quantities look like they are for a whole system, it shouldn't take nearly that much just from dropping the pan and changing the filter.

To drop the pan and change the filter you need about 3 or 4 quarts (that's 6 or 8 pints) of tranny fluid and 2 or 3 beers.

 

I would be concerned about the effect beer might have on the bands and clutches.
