I noticed a pretty good leak from the tranny. So I looked around and fluid is on the exhaust pipe and all over the side of the tranny. My first thought was the o-ring on the dipstick tube. So I replaced it this morning and went for a ride to the car wash. I tried to clean it all out under there. When I got back to the camper and checked again it looks like the leak is coming from the fittings where the rear tranny line screws in.
Has anybody else had this problem? Do I just replace the brass washers?
It has to be a banjo bolt because the other line connected runs toward the front

 

When i pull the rear tranny line(return from the cooler) to do my tranny flushes, its just a flared line with a nut that holds the flange into the tranny port. that said, I would try to snug it up and see if that cures your leak. if not, it might be a cracked line.

 

The rear line screws in but it's in I guess a banjo bolt. It has another line that goes back forward on that bolt. It has the brass washers just like the brake calipers. I was going to try to mess with it before work but it poured down rain and the ground was all soggy

 

Besides the coated sealing washers, there are O-rings in the Bypass Valve that can also leak at the rear fitting. Cooler Bypass Valve Kit - 36605-02K - Sonnax The banjo bolts torque 27 ft-lbs for the rear and 22 ft-lbs for the front.

 

I called ford trying to see if they have this since I have to have my truck and I'm 6 hours from home. Of course the parts guy had no clue what I was talking about. He put me on hold and went and ask his diesel tech and tranny guy and neither of them knew anything about it either. He is saying that the lines screw in the case on the tranny.
I tried ebay to see if I could get a part number. No luck.
I did see a kit to delete the bypass line. But I still have the same problem. I need my truck now.

 

Wish I was close to you. I "may" have some spares.

EDIT: Checked my stash this evening and didn't have any. Sorry!

 

Where are you located? I'm in nederland tx. I'd be happy to buy it off of you

 

I'm about 2 hrs west of you.
Here is the Ford part number for the banjo bolt gasket kit. 2001 Ford F-250 Auto Trans Modulator Valve | FordParts.com Sometimes the terminology for the parts makes them difficult to locate. I deal with this a lot when ordering over-the-road and heavy equipment parts. That's why I prefer to look them up online when I can. Hope this helps.

 

Thanks brother I'm fixing to go back to Philpott ford now for that. I did order the other kit but it's being sent to the house. And I really don't want to make the 6 hour drive with this leak. So ill buy their o-rings for the ride and rebuild it with the other kit when I go home
