E40D Front Seal, what else should I do when I have the tranny out?

Well after towing a trailer down to Pueblo for the USP heads up race. I was 190 degrees on the gauge the whole time (not bad considering it was 105 driving down there). I puked fluid out the front seal the whole time. I just kept pulling over and making sure it was full. I made it there and back.

But now its time to pull the SOB out and make it stop leaking when it gets warm.

Plans of now are doing a Downpipe and the same time, possibly Donuts (but I really dont want to unless you guys think its a good idea, they aren't leaking now). I will be doing the seal and all new fluid. I dont want to tear the tranny open to do clutches and bands right now, I will do that if it is slipping or at that point I will just stick the ZF5 I have for it in.

What else would you guys do while the tranny is down? Would you do a different convertor? Dont have a whole lot to spend on it, but would rather do it now than later. Eventually the truck will have stage 1 sticks. Im not gonna tear it down until two fridays from now and hopefully finish it in a day or I have saturday to finish it.

Thanks Matt

I think I would do the seal with the parameters you have. I know there are better ones to put back in then OEM.

You want a Viton seal. That's the material. While you are there I recommend also changing the torque converter hub bushing, right behind the seal. It should be less than $10 and it could be the reason the seal failed.

It's like any other bushing, nothing special. A standard bushing tool or the right size pry bar will work it out.

Re: E40D Front Seal, what else should I do when I have the tranny out?

I am starting this project today and hoping to have it done by tomorrow.

I picked up
E9TZ-7A248-B
3C3Z-7A248-BA
E9TZ-7A136-A

from ford today, but we couldnt find a part number for the bushing. So I need to find the part number for the bushing and I will have everything but transmission fluid to finish.

Anybody have the Part number for the bushing?

Well its out... From now on, I will no not to ever try and take these trannys out my self...

Found the leak.




And here is next to a C4 I built for a race car this week...

Why check it? To me, if it is not a brand new bushing it's getting replaced.

The only way to accurately check it is to remove it and look for wear or damage. Once it's out, why would you put a used one back in?

I would completely agree. But I am now finding 3 part numbers for the bushing, so I guess im gonna take the bushing out and then take it to transstar and see if we cant match one up.
