I lost my transmission (E4OD) today

I was driving through a parking lot today after shopping and all the sudden I hear a loud bang, the engine almost stalls and I lost all forward and reverse gears. I barely made it to a parking spot. I had to rev the engine up to get it to crawl into a safer spot. I hear a loud whirring sound when I put the truck in any gear and it gets louder and faster with RPM. I heard some clanking as I tried diving into a safe spot, so I thought I lost the driveshaft and it was dragging. Driveshaft is fine. Everything looks normal under the truck, nothing leaking fluid or hanging down. I hoped maybe there was a leak I didn't know about and adding fluid would fix the problem. Nope, added 4 quarts in the parking lot, checking for movement every half quart. No change in symptoms. I know it is overfilled at this point but that seems to be the least of my worries.

I literally had no warning before this happened. The truck was driving normal, like it has in the past 7 years. I drove about 25 miles on the highway to get to the store and not one single sign of an issue.

I'm pretty sure this transmission needs to be pulled and rebuilt. Has anyone had my similar symptoms? If so, what was the cause?

not that exact problem mine tranny started over heating. When I did the fluid and filter change there was heavy crud on the magnet and shiny particles in fluid. Torque Converter and plantaries are done. I can drive it 10 miles and tranny temp goes up at least 50 The cheapest I have been able to find a rebuild is 1600 from Tom Rivers. The remans are running about 2200. What makes them so expensive is the internal mods that have to be done that were weak areas from Ford. It you can get all the parts cheap you can do a zf5 swap. My local pull a parts sells manual trannys for around 75. Do they have a zf5 diesel ok course not. When you start look for a tranny make sure it is for diesel. The gas has a different bolt pattern.

It's the labor and warranty that makes the price go up so much. A rebuild kit is a few hundred if there are no broken parts in the trans. I have a spare E4OD in the shop but the fluid in it is burnt so it probably needs a rebuild just as bad. Still debating if I want to rebuild it myself or throw in the towel and get a reman unit for about $2000.

I still need to pull the trans down and investigate. It could be something less expensive like a flex plate or TC. Unfortunately, if the TC went, it could have sent trash into the transmission.

BUMMER!

Hope you can figure it out. About the only other thing you could do is drop the pan before removing the transmission. If there's clutch material in the pan then it will definitely need a rebuild. I've read horror stories about the E4ODs.

FWIW, I bought a 7.3l IDI from Eagle Mountain Auto Salvage in Ft. Worth, TX a few months ago. The truck it came out of had a zf5. I want to swap an E4OD into my Bullnose so I didn't even check out the transmission.

Hard to say until you rip it apart.A loud bang could of been the input shaft snapping I suppose? That would be an easy and cheap fix.With you claiming revving it made it go though,I'm pretty sure that rules that out.

Well, it may have been gravity moving the truck, that's how it felt. When I put it in drive and reverse I feel it engage the gear but it will not move forward or reverse on its own power. I will try to make time today to get a line pressure reading but as it sits now, I'm going to guess the line pressure is normal.

Seen this happen on a 4r100 which is really similar to an e40d. It was the rear planetary drum stripped, he fixed it with one from a spare c6 he had lying around. Of course everything had to come out of the trans but if your in a pinch you could investigate

Maybe you'll get lucky and it's just the input shaft behind the converter..

I tested the line pressure today and that does not seem to be the issue. 60-70PSI idle in park, 100-110 in gear at idle. It went into limp mode during testing, so pressure went up to 130-140 in park at idle and pegged my gauge when in manual 1st gear. Increasing RPM increases the pressure accordingly.

Seems to me like the TC and front pump are working properly. I can feel the clutches engage but there is no movement in the drive shaft at all. All I can conclude at this point is there is a mechanical failure, most likely in the rear half of the transmission, so it needs to be pulled and gone through. Since I have to completely disassemble the unit, I will go ahead and get a rebuild kit. Any damaged parts will need to be ordered or sourced from my parts unit.

Did they have a nice selection to look at?

The only reason I went to Eagle Mountain in Ft. Worth was to look at the 7.3l turbo IDI. They wanted $250+ for just the turbo, so I bought the entire engine for $650.

I reviewed them well on Google because they had something I needed and the folks were friendly. They have a closed yard so you have to be escorted on the premises. I waited 45 minutes to see the engine on a pallet in the warehouse. The good thing about their yard is that they put their stock online:

Car-Part.com--Used Auto Parts Market

There are better salvage yards in Dallas down on Jefferson. They actually have a few IDI trucks I pulled injectors off of a month or two ago. I didn't see any Bricknose or OBS IDIs in the Dallas salvage yards. I'm definitely on the look-out for a 4x4 E40D from an IDI truck though.

I drained the torque converter today and found some fine metallic particles in the bottom of the drip pan. I have the transmission almost ready to pull. I have a friend from work that is going to come over on Saturday and help get it on the bench. I ordered a rebuild kit, F5 front pump, Billet milti-clutch TC, and a Transgo Tugger kit. I'm holding off on ordering too much more until I find out what happened in the trans. I do want to upgrade to steel planets but I'll see what's in there first.

Does anyone know if the F5 pumps included the upgrades found in the code 62 kit? I ordered a code 62 kit as well but I don't want to install it if it is unnecessary.

The F5 pump is simply high volume.The tugger kit alone will provide you with all the required mods (save for the metal drainback valve) that should be done.

Thanks F250! That will come in handy when I get to installing the tugger kit. Did I read it right where it says you can be going 60MPH and shift into manual low? I never tried that on any vehicle fearing disastrous results. It could be useful for engine braking when heavily loaded, though. Have you tried that on your truck?

Nah I've got hydroboost brakes on both trucks.No need.With the f450 and it's massive 4 disc calipers,that stops even easier,even with twice the load.I do sometimes manually downshift to 2nd with the f250 but even then,not generally.
