Hey I see somebody has a problem with the E40D.
I have a 93 5.8 with the E40D and I was pulling the boat this weekend when it started shuddering into gear (only twice) It seems to vibrate in the floor around 50/55. I have 175000 on the truck , bought it at 140000. I changed the fluid /filter at 160000. what should I do now? Also I read about the zf swap, sounds good, does anyone have more info on whats needed
