DNE2 OverDrive Leaking Bad T19 Borg

[Kingralph88]

Has been leaking very little (couple drops here and there) but today I seen a shine from under my truck when it was parked.

Check the photos out, looks like a leak on the speedo line, also leaking more from a part I am not aware of, please let me know if you know what this is on the top of my DNE2 overdrive unit.

Should I replace the speedo line, and the other part that is leaking or should I reseal them? Not sure if that is possible. Let me know your thoughts

In my unexpert opinion, the leaking part for the speedo is probably a bad o ring seal. The other thing that's leaking looks like a vent to me. If it is, then it's leaking from having too much fluid inside the OD unit. That means that you have a bad seal between the transmission and the DN2.

That’s probably what’s going on, damn!

Am I looking at the correct seal here?
Check photos attached.
#29 input seal

It could be that one. I'm just throwing out guesses here. I'm certainly not saying that's what is wrong. It just seems logical to me. Hopefully someone with more experience with these than I have will either say that I'm right or that I don't know what I'm talking about.

Checking transmission oil level will give you a pretty good idea if IDI is correct.

Check trans oil level today & it’s low, I do think the oil is leaking past the seal between the trans and the OD unit

Does anyone have an idea of what seal I’m working with? I for the life of me cannnot find any info on a seal in between.

Maybe the rear output shaft seal, but that would be on the back end of the OD unit connecting to the drive shaft if I’m not mistaken?

Got some photos of t19 below

There's a seal on the back of the transmission. When I first got my Blue Truck, it had a 4 speed in it. That seal was bad because I almost got a bath of 80w/90 when I finally got the transfer case loose from the mess of RTV that held it to the transmission.
