This is probably overly obvious but verify the tranny's fluid level.

Park it on the street till you confirm it isnt leaking. Tranny fluid is a bitch to clean up. Park on gravel if possible.

I take it had the correct amount of fluid before the test drive? And it worked fine on the test drive?

Dumped fluid from where? Where does it appear to be leaking from?

Did you get a 30 day handshake warranty or more like a "tail light" warranty (when the PO can't see the tail lights anymore), the warranty is over?

X2 on ck the fluid properly, but ck it first before trying to drive it anymore. Park it on level ground and follow the instructions on the dip stick.

Hot, in park....read the hash marks. Worse case before you take it to a trans shop, do a fluid and filter change.

It appears that have came from a old line between transmission and transmission oil cooler line. On passenger side. And warranty was tail lights which is fine it's not my primary driver any way so I can work on in my free time. The fluid that came out is black. So any pointers there would be great everyone is telling me I can't change the fluid or it will not drive agian.

Did you buy it with a good transmission or a questionable one? Might not matter now, cause you are paying for the work for sure.

Black fluid is burnt fluid can ='s bad news. I'd change the filter, flush it ...and the converter, and the cooler, slack ck the bands and button it back up and hope for the best.

Post your VIN, in fact post your complete warranty plate (metal plate riveted to the driver's door) and I can decode it for you.
No idea on C6 capacity, I'm 1400 miles from my shop manuals right now.

Like mikeo0o0o0 said, post it here and he will decode it.

1. If the converter is dry then these will hold about 10 qts. If the converter is not drained and you are dropping the pan put 5 quarts in and check it. Depending on how long the pan is off it could take up to 7 quarts. You just have to add fluid a half quart at a time after the inital 5 quarts.

2. The C-6 also has a very large fluid capacity at 24 pints, including the fluid in the torque converter. 24 pints ='s 12 qts.

3. I looked in my 1979 Ford Truck shop manual on draining and refilling the C6 and it says to add 3 quarts of fluid after you remove the pan, drain the old fluid, and re-install the pan. My Haynes manual for '73-'79 Ford Trucks says to add a little fluid at a time since fluid capacities can vary and to use 4 to 5 pints as a starting point. Don't forget to use a new gasket.

4. Just dropping the pan and changing the fluid and filter. I'd start out with 4 quarts, start it up, then fill to level.

F25 = F250 2WD Pickup.

Y = 360 2V

C = Oakville Ontario Canada Truck Assembly Plant.

W26592 = 1975.

Trucks assembled in Canada were also sold in the US, could have been ordered by the Atlanta & Pittsburgh Ford district sales offices, possibly other offices as well.

DSO code stamped on the 3rd line-far right of the Warranty Plate, will decode to the office your truck was ordered from.

If 14 = Pittsburgh, if 21 = Atlanta. If another code, post what it is.
