I am dealing with some leaking in my C4 in my falcon and hope you guys can give me some advice. I realized that I need to replace the gasket on the tranny. Even though it is a new gasket it need to go and I will try to replace that this weekend. I have check the tranny lines and it all looks fine and see no leaks there. I have read online that sometimes that the shifter does leak but not sure if that is the problem or not.
I am attaching some photos and hoping for some solid advice.
1. The car seems to drip daily.
2. It will leak more is on a slop in the driveway rather then level in the garage.
3. I have tighten all the nuts on the tranny gasket and it still seems to leak.
4. There is a leak above the tranny mount as it seems the bolts on the tranny always have a drop of fluid on them.
I would say it is the front pump seal and is blowing back onto the trans and dripping from where ever. Does it leak more with the nose down hill and less with the front up hill? If it has sat for a while the area on the converter that the seal rides on will rust and knock out the seal. I have used additives and in some cases this will work. And if you over tighten the pan bolts it can bend the pan at the bolt holes and may cause a leak there that you did not have before. And with the bolt holes bent a new gasket may not seal if the pan is not fix before installing.
the tranny bolts are tight now but should not be overtightened as I have been very careful.
All the drips that you see are from sitting not driving. I have never parked it the opposite way down a hill, either I park the car with the rear towards the bottom of the slop or on a level. It seems to leak more when the rear is down the slop then on the level.
This is what I meant when I said the leak from the front seal may be blowing back on the trans and will drip from the lowest place. When it sets over night is the biggest puddle in one place near the front of the trans?
I would replace the small rubber o-ring that is just behind the kickdown linkage arm, I have seen them leak a lot in the past, they leak more when parked. Front seals tend to leak when the engine is running and the pump is making pressure. The o-ring may be hard to find, you might want to swing by any trans shop and see if they have one in a old kit box, they might even give it to you, I would.
most of the fluid that drips out of the tranny does come from the rear behind the pan. It seems to concentrate towards the back of the transmission. I left it in the garage last night and I will post a photo when I get home of the position of the leak so it give you so more insight.
The tranny leaks if I drive it or not does not seems to matter.
I will look for a kickdown linkage O ring. I think it may be something odd like this causing the problem because when I look around everything looks good but it continues to drip. If I take a rag and remove the fluid that I have shown photos of it will appear within a few hours.
