E4OD won't shift into any forward gears, but reverse works
Hey guys,
I've been searching around here and Google for a while now but haven't found anyone with my exact same symptoms. I have a 95 F250 with 7.5 and E4OD. I was towing my Jeep and trailer out for the weekend a few months back (its been parked since) and heard some noise coming from the trailer. So at a stop light I put it in park with the engine running for a second, went to put it back into drive and it hasn't gone back into drive since. Reverse works perfectly. Fortunately I was able to back up onto the center divide, unload my Jeep and back the truck onto the trailer and tow home with my buddies Chevy. Anyways, its been dead since. Any ideas on where I can start to look?
None of the forward gears work at all. I'm sort of at a loss here. I'm good with motors, transfer cases, axles, suspension yada yada, but not transmissions. Any help would be greatly appreciated.
Thanks in advance

The easiest way to determine what broke is to pull the trans out and tear it down. Whatever broke is inside the trans and requires a rebuild to fix. What would it help to try and determine exactly what failed first? Now you need to go inside and find everything that is damaged and in need of replacement.

So there's zero way to diagnose anything with it still attached to the vehicle? No chance of it being something simple ie valve body, linkage, solenoid, line pressure etc.? Any idea of what might have crapped out? I'm a sucker for specifics
Thanks

I did forget one possibility. There are feed bolts that can loosen and you lose pressure to apply the clutches. Drop the pan and remove the valve body. Then find and tighten these: https://www.ford-trucks.com/user_gal...id=253194&.jpg

It can't be a solenoid. It can be a broken sun, a broken shell, a broken shaft, a stripped spline, etc. There are a bunch of things it could be.

Yes they can.
Every failure has some exact point where the failure occurred. A crack can begin and spread accross the part. As long as it hasn't gone all the way through the part still functions. At some point that last bit fails and that part is all done.

I've been looking for a f250. If its a crew I'll seriously consider it. E4od is not too big of a deal to rebuild. I've been through mine twice and a couple of buddies also. Its a very stout transmission if updated and the sonax parts installed.
