How much atf should my ford c6 take
 

Hi all . I am now running in my trans with the wheels off and axle jacked up as its never had any use since the rebuild. I have a oil cooler to the front of the car ( radiator type ) i currently have around 6 litres in it and have had it running through the gears but i have been told to check the level whilst its running ? Ie opposite to how you check the engine oil .

What do they normally hold ? Its a c6 with reverse shift pattern. B +m high stall torque converter @2800 rpm

cheers guys

Just did a search on the forum and found a post that states around 13 quarts, well 1 q is 1.13 litres , and i have around 6l so far and seems to have another 8 odd litres to go. If this is the case how do i get it to work around the auto box ? Do i just keep adding or do i wait until it shows on the dip stick that it needs more. Am afraid to run it dry

Put the rear on jack stands
put 4 quarts in
Start in the N position
Fill to the add line

Check operation of trans and then top off.

hi all . i had the car running today jacked up on axle stands . run through all of the gears and in reverse . its taken around 6 liters . my concern is that i thought it takes more ? and i also have a trans cooler in front of my radiator . albiet its small .

so will the gearbox fluid - pump around the external cooler raditor ok ?

cheers

my 1981 c6 takes 25 pints.
25 pints = 11.8294 liters

wow , i thought as much , so how can i get it to drop the level so i can add more ? or would you keep adding even though it measures max on the level line ??

the torque converter takes maybe about 1/2 of the total fluid.(just guessing on that one)
i would imagine run it and keep a fillin.

ok will try that . do you reckon even though i am seeing the max level once i start adding more it will feed its way around . also does the c6 feed out and then return through the trans cooler itself ?

cheers

IMO, do not overfill it at any time.

Did you drain the convertor or did you just drop the pan?
C-6's usually have a removable plug on the convertor, which can be accessed through the back side of the flex-plate.

As far as plumbing you trans cooler:

When I worked for Ford, I recall a TSB advising that dealers should always install an "H-Fitting" in the line if the vehicle was equipped with a tranny cooler, particulary in cold-climate regions like ours.

This fitting was designed so that the tranny would not be starved for oil due to cold-temperature oil viscosity. Tru-Cool brand coolers have a similar technology built right into their "LPD" series.

mine didnt. i wish it did.....

I had to put fluid in the new convertor on my Pontiac before installed the convertor and trans. The guy that built it insisted that I did.

I think your C-6 should take about 11 quarts with the convertor.
