Hi Moses, I read a lot of post with regards to the E40D Trans. I'm adding mine to the list. I have a 95' F-150 4WD, it has a 351 with the E40D. I do not believe I am "Hard" on my truck but if the trans. is bad this will make number 4. The truck has 150,000 until I bought it at 114,000 I don't think it pulled anything. Within a couple of months of buying it, seals blew loosing all the fluid. Replaced with a remanf. unit 20,000 and one year and ($2400) it goes again. This time no remanf. yard tranny, low mileage I have them check it over new filter, oil and ever it takes make it right. 3 months
