REALLY strange trans problem!

[J. Steinbeck]

Hello everyone! This is my first time posting on this site, so if I say anything stupid, please forgive me. I am here, though, because I am having a pretty serious problem.

My brother has a 2001 Ford F350 dually automatic that he has been using as a service truck for his diesel repair company. The truck had two injectors going down, so I spent the better part of yesterday afternoon helping him replace them. When we finished, the truck ran like a champ.

This morning, we were going to start the truck up and drive it around a little to get a good charge on the batteries. (Before yesterday, the truck had not been driven in almost two weeks.) The truck had some trouble starting, so we took one of our other Fords (a 2006 6.0 Superduty) and jumped the service truck off. The truck started pretty easily, but we soon ran into a big problem- when we put it in gear to pull out, NOTHING HAPPENED. We put it in every possible gear including reverse, but the truck would just rev as if it were in neutral.

Now, my question is, what in the world could have so suddenly gone wrong? Is there any fuse or solenoid that we could have blown when boosting off the truck that could cause this issue? As said, the truck ran great and shifted great on our test drive just the night before.

BTW, we looked to make sure nothing had come unplugged and everything appears to be in order. I also noted that when the column shifter is moved, the actuator on the side of the trans moves as it should.

Sorry for the long post... I just wanted to see if anyone on here might have some suggestions before we tear into this thing in the morning.

I'm not much on tranny issues but I thought I would at least you to the forum... I hope someone has some answers for you shortly....

Is the overdrive light flashing at all. Does the fluid smell burnt. Is the fluid brown. How did the tranny work the day before or before the injectors went out. There are soleniods inside the tranny valve body. They work electrically. The black box on the side of the tranny actuates the soleniods. That black box may have went bad. If it did it may not be operating the soleniods. I doubt the tranny took a dump while sitting over night. But it wouldn't be the first time I seen a torq converter go out like that. Mine did once. Ended up just rebuilding the whole trans.

could be you leaked all your fluid out, or something in your valve body has been plugged up and stopped or slowed down the flow of tranny fluid through the right hole.

Can't help with your trans problem, but

Welcome to Powerstroke.org

Thanks for the welcome, folks.


We drained the transmission and put in a filter kit, but it did nothing, so we pulled the whole thing. We aren't transmission experts, though, so we're still not sure what the problem is. There wasn't any metal in the case, and when we turned the input shaft, the tail shaft on the transfer case turned as well.

At this point, I guess we are leaning towards the torque converter.

Is there any way to test a converter while it is out of the truck?

Thanks again for the courtesy and prompt responses.

Just in case anyone was wondering, I thought I'd leave an update. The trans pump was blown, and the bullgear at the input of the transmission didn't look too hot. We're having the whole thing rebuilt now.

I guess after 140k of hauling an 11,000 lb. service body truck, the trans had just taken all it could. The strong performance of the engine after our injector replacement was probably just the straw that broke the camel's back.

Once again, I appreciate that ya'll tried to help. Have a good one!

Thanks for the update and glad to hear your gettin' it fixed up!

FYI, big country. The black box on the side of the trans does not operate the solenoids in the trans. The computer does that.
Steinbeck, If it isn't already in, make sure it doesn't have the grey seal in the front pump. It's death to the tranny on a hot pull.
