I have been pondering on what to do about a tranny vent for a week now. I thought today, that if a fella siliconed up the inspection cover and in the little groove in the bottom ran a small vaccum line out of there and up to a high and dry spot inside the engine compartment he would have a much more water proof rig. Does that sound like a good idea? I want some feedback before I do this, but everytime I drive my truck through deep water I get real nervous about water entering the tranny through that little hole and ruining it. I can't see why it wouldn't work, as long as the tranny has some way to intake and expell air albeit a very little bit at a time. That's why I don't think it would take much of a tube to do the job. Any help is appreciated....

Come on now, am I the only one out there who drives through deep water and big holes? Somebody has an idea as for a way to keep water out of the tranny.

I thought there was a couple posts about this a week or two ago but maybe I am mistaken.

If you do find any info I would like to know about it. I plan on taking the new truck into some serious stuff.

You're right, this topis was brought up a little while ago, but I never understood the consensus of those involved. I would like to have a very clear understanding before I start moidfying a $1500 tranny that is still under warranty. I will try and talk to a dodge tech and ask his opinion, when I do this I will post the results of my research.

I did my 727 while it was out. Behind the torque converter, where the vent hole is, I tapped it to a 1/8 NPS thread and drilled a hole in the tranny housing above it. This line ties into the vent line off of my t-case and runs up to the engine compartment.
