Hey guys! After googling around for answers, this seems to be the right topic to get to the bottom of the problem with the E4OD transmission on my 1990 F-250 7.3. Im a decent mechanic, but not that skilled in the technical terms of the english language, but hopefully we will understand each other somehow...
The symptoms are similar to many of the other ones here. When put in DRIVE, the truck feels underpowered, engine revs up with very little motion on the truck. Takes forever to get the truck moving. I notice when I eventually get up to normal speed, that the speedometer keeps "flickering" while the transmission seems to go in and out of neutral and drive inconsistantly, but still with forward motion on the truck.
Seems to me that this might be an electrical problem, as the transmission fluid seems to be at proper level and clean when checked. Maybe a faulty contact point. The problem keeps coming and going, some days the truck handles like its no troubles at all, but lately it has occurred every time Im driving.
So where would I start troubleshooting with a multimeter? I've had my truck for about 4 years, but im not that familiar with the electrical components of the E4OD, so I dont know what to look for.
Another thing. Before this problem occured, the truck would sometimes start to roll after transmission was put in PARK position, with an awful metallic sound following. Like some cogwheels are grinding or slipping on each other. Dont know if its related though.
What do you think?
