BIG Transmission fluid leak

[454cid]

this is too small to be a factory hole. It is in the middle of the hump in the cap.

It's not a big hole. The middle of the cap is exactly where it's supposed to be.

But did you go look at the link I posted..

yes I did. I didnt take the rear housing off though. Did you see the photo I posted?

...and you may as well change the bushing too. It could be worn making things worse.

Yes...not sure why you think that's too small to be factory? It's dead center and where the factory puts a "weep" hole in some yokes. Do you think it got there some other way? Don't get me wrong; I'm not trying to be combative - just curious what your thoughts on this are.

That looks like it might be from a 32 tooth slip yoke, not the 27 tooth that you have..... on my monitor it's almost the size of a paper plate, Though. It's also not installed. The shape changes a bit when they're pressed in, and peened over.

The bearing and o-ring require the tailshaft housing to come off, which you already said you didn't do.

sorry I thought you said end cap, my misunderstanding.

I took the drive shaft out. I took the yoke off the shaft and poured a little fluid in the yoke. I poured out the cap at the end of the yoke. (where the u-joint connects.)
I'm guessing that the fluid was draining out of the yoke and then I did not have enough fluid to move the truck. But what I don't understand is. The last time I took her out. If I let her sit for a couple seconds, the transmission would actually work for a short bit.

Yeah... that IS the same problem that is talking about in my earlier post. That hole is there for venting. At least that is what I was told at the dealership and at a few transmission shops. I replaced the toilet and it didn't leak anymore

 

[Outlaw910]

I don't disagree, but every design is subject to field revision. That's why I was thinking the TSB would clear things up.

It was my initial thought that the tailshaft bushing has failed, but again it's been forever since I dealt with this particular issue.

You're right..it is a vent. But...there is some silicone or plastic in that hole that gets brittle over time
