I have a95 f250 7.3 with the e4od. The od light was flashing with hard shifting when i bought the truck but only intermittently. After a month of owning it i was driving to get fireworks and the trans went into neutral but does hold in park. Bought a 2 wheel drive tranny and had a guy build one from the 2, mines 4wd. Got it together he drove it around the block fine then went to move it again and back to no gears. I replaced the neutral switch, brake switch and put a new cooler on it. I do also have a new valve body and solenoid pack but want to make sure to check everything outside the trans first. Can anyone point me in the right direction.
