E40D Transmissions

[gbear]

How do you all feel about the E40D Automatic Transmission? I'm gathering
Info for some one who is building a bad "Lighting" running about 400 hp.
I've got one in my Powerstroke and haven't had a lick of trouble. but I would
like to hear more from others. I've heard that the 97's and up use tougher
planetaries?

I hope that's right. I'm fixin to start using my truck to make a living in a couple of weeks pulling campers and mine has that same tranny(2000 F-350 PSD, 39,000 miles) So far I haven't had a lick of trouble with mine:pray: Main thing is (Maintenance) Change that fluid and filter every 20 to 30,000 miles. Probably more frequently if used in a 400 hp Lightening. Wouldn't you say so Marc?

Thanks Deeno, You and I make two that like them. Hope to hear more.

I don't know what year may use the heavier planetary but I installed the HD planetary for overdrive in my '95 E4OD when I had it apart.

The HD part uses a steel planet carrier verses aluminum for the standard unit. While mine was in excellent shape, I thought it would be cheap insurance for towing in OD. The price was $150.

Was there a problem when you had it down or were you just installing mod's?

I tore it down to replace the output shaft. While I was in it, I decided to install the improved OD planetary.
