I've tried and tried to find pictures for comparison so that I didn't have to bother anyone, but no luck :/
1991 F250 Diesel 4x4
I took it to a reputable transmission shop for a flush and filter change/ inspection and to get the cooler lines at the radiator replaced because they were rotten and leaking transmission fluid all over. $200 was the cost. Get home and notice that there is quite a leak ,but unsure where from. Called the guy we discuss it and I end up finding that the pan bolts were merely finger tightened. I could turn all but one with my fingers. So I snug them up and am keeping an eye on it. Still leaking. The guy says bring it back. Ok, I'm gonna. However I would like to go loaded for bear I have turned many a wrench but never transmission work and never diesel nor 4x4. I've had this truck for about six months. Something doesn't look right. (See pics) I see shiny metal. And it looks as if there are no gaskets
? Like I said, I don't know much about this subject and any help would be appreciated. Thank you



What is that thing protruding with a drop on it?





Upper right corner of photo(bare metal) is odd looking to me

 

The first pic shows fresh fluid leaking from the bellhousing drain tube. That would be a leak at the front pump seal (transmission input shaft basically).

Second pic, another view of the bellhousing access cover. No gasket required there, it's just to keep trash out of the bellhousing.

 

Please ignore the redundancy




More shiny metal





What is this part? There is a noticeable gap

 

Wow that was quick! Thank you. That sounds like it's gonna cost me though :/

 

You said you've turned many a wrench but never any transmission work. Are you comfortable removing the transmission yourself? If so then once you have it out, all you have to do it pull the converter (which just slides off the stator support/input shaft) and the seal is right behind it. I don't think you even have to pull the pump to change the seal. Then it's just a matter of making sure you got the converter seated right and bolting the trans back into the truck.

Thank you for your help
I'm not a fearful person when it comes to tearing into something unfamiliar, confidant that I can put it back together with the help of the boards here. I do know my limitations, however, lack of help, place to do it, proper tools and strength. I wish that I could do this myself. My head says I can, my body and circumstance, not so much :/
Is this seal issue something that's gonna just let go someday and leave me walking? can I drive the truck if I keep an eye on the fluid level?

 

yes.
no.not advised.if the seal lets go,or if the issue isn't the seal itself but the pump bushing walked forward,then you could loose all fluid and be stranded.possibly worse,with burning up the trans if you don't pull over and shut it down in time.
you've got to get the trans pulled to fix the issue.where it's leaking from is supposed to be dry.not full of fluid.that's why you see no gasket there.

 

Hi all. Thank you so much for your input. I'm having cervical spine fusion in two weeks, hence my inability to do any part of this repair/diagnostic.
Looking for more input concerning this issue, if you don't mind
Here's some info to consider:
I purchased this truck 8 months ago for $2500. The fella I bought it from is a retiree who bought a new travel trailer and new version if this truck.
He told me that he rebuilt the motor 5000 miles ago due to it overheating severely. He was pulling his new trailer in the mountains when the water pump blew and he kept going to get to a safe place. It (supposedly) has 150k on it. The motor seems strong and the trick is straight and only the bed is rusted through in places. I've talked to the Trans shop and he had quoted me as follows:
If it's the seal or torque converter is gonna cost $7-800. With upgraded Billet plate/parts
If I need to have the Trans R&R'd it's gonna be $2200 again with upgraded parts. I lolilive in a 1968 '30 Airstream therefore I will have to replace this truck if I end up selling it.
Questions:
Should I get a compression check to verify the motor is sound? What else should I check? At some point I will be (hopefully) back to turning my own wrench ,so the regular wear parts I can handle in the future.
I would really appreciate your thoughts and recommendations
Thank you so much!


Should I go ahead and have it R&R'd rather than spending money now then probably having to spend money again in the future on the same trans?

 

It's probably leaking right from the pump gasket,

 

As far as the engine, if it runs good and pulls good and doesn't drink oil, I would say just drive it and nut worry about it. As for the leaky trans, I would just try a seal replacement and see what happens. Now if it looks like Puddy's, that's a different story. And you won't know until you crack it open.
