Wow! this is a great thread on E4OD! Thanks for taking the time to make it.
The E4OD in my F250 2WD is out of the vehicle, and I am going to do some basic maintenance. This tranny has 90,000 miles on it, and it had the fluid and filter changed at about 50K mi, right before I bought it. I am the second owner.
A couple of years ago it dumped fluid out the bell-housing inspection plug while helping someone move house in the mountains of CO. After that day, it never leaked much until about a month ago when it dumped fluid out (mid-summer) in front of my house. So, I decided to take out the tranny and replace the seals/filter/fluid, and maybe have it flushed.
So far, I have purchased a new pan gasket, a new filter, a new front seal, a new rear seal, and a new O-ring for behind the pump. No work done yet, and now I have a couple Q's after reading through your fine posts here. I hope you don't mind.
I don't want to do a full rebuild, but wondered what I should do. Which seals to replace, and which bushings, if any. You talked about the front seal and bushing...sounds like you'd recommend changing at least the front bushing. Would you recommend changing any other bushings?
Your post and pics didn't show anything about the rear seal, and I can't find anything about it in the tranny section of my shop manual. How do I remove the rear seal? We've tried pulling it (forcing it) while the tail section is still on the tranny. Doesn't seem to work well. Can you recommend a better method?
I only use my truck for light duty around-town stuff. But it started spewing fluid on me while doing light driving, so this is why I am replacing seals and not doing a full rebuild. The fluid is darker red, but doesn't smell or look burnt
From everything I have read, the problem with these (or any) trannys is heat. I do plan to add a tranny temp gauge and then an aftermarket tranny cooler (in addition to flushing the lines to the radiator). Another thought I had was to change the pan to a deep pan, like those on 4WD (mine is 2WD). That would let me add more fluid to the tranny for increased cooling. But now I wonder, is too much cooling a problem? Do you know if there is a minumum operating temperature?
Lots of Q's, I know, but I am excited to get the new seals in and get it back to a working truck.
Thanks for any.all of your replies!!!
