Original vent location:




I sealed the original vent using a threaded plug of the same size as the barb fitting purchased for the new vent. This way you can use one tap for both fittings. And you do not even have to drill out the old vent. The hole is close enough in size to drive the tap through.

Remember, its only a vent, so your options for plugging it are practically endless.

I recommend using teflon tape on the threads of the plug.

Drill your new hole slowly while holding a vacuum hose closely to catch the metal shavings.

Check the location of the new hole several times before drilling. Be sure NOT to drill into the front pump assembly.

Here's the newly located vent ready to accept a rubber extension hose:

I often wondered what people were doing about the metal shavings after drilling a new vent hole. Thats a nice shiny trans.

How big of a pita is it to drop the tranny and install one of these?

Big time PITA so far as I am concerned on the couple times I have dropped and reinstalled a tranny in my TJ.

Does anyone have information about droping the trans?

I am guessing it would eb the same for a YJ. I need to do this to my YJ as I got water in to yet again last weekend. Lucky for me no damage was trailered home.

Here's the quick and dirty write-up without pics :

1. Remove tranny mount from tranny skid plate/crossmember
2. Unbolt bellhousing from motor
3. Unbolt starter
4. Remove driveshafts
5. Unhook tranny cooler lines
6. Unbolt t-case shifter linkage
7. Unplug crank position sensor
8. Unplug speedo gear
9. Unplug other miscellaneous electrical connections I forgot about
10. Remove kickdown cable and gear select cable from tranny
11. Remove inspection plate from front of tranny
12. Unbolt 4 bolts that hold torque converter to flex plate. You have to rotate the flex plate to get at all 4 bolts.

Be sure to support the transmission once you remove the skid plate/crossmember. Also remember to drain the fluid from the pan before you start.

You can also remove the t-case and drop it separately to make it a little easier to handle, but I usually just drop the tranny with the t-case still attached.

The new vent was located as close as possible to the old vent.

I wasn't sure exactly where to put it. I've seen a few write-ups that move it further back on the case. I thought it would be best to keep the vent as close as possible to its stock location, so I chose the location according to that.

That makes sense, but you mentioned about the pump assembly.

I was just curious how you knew that location would not hit anything under the hole.
I'd really like to try this mod at some point. I do VERY few water crossings, so I'm not sure how cost effective it would be for me. My Atlas would also make the assembly MUCH heavier to deal with on the garage floor.
If the tranny ever has to come out for service, this is getting done for sure.
Thanks again for the pics and writeup!

It was a lucky guess.

I held my finger at the proposed spot and looked at it back and forth and at all angles. I had a few buddies also look at it to see if they thought it would clear that front plate of the pump assembly that you see directly behind the torque converter.

I drilled slow and once it was through the case I made sure it was not drilling in to something else.

I did not have the tranny apart since a builder did that work for me. I was not really sure what to expect when drilling in that location. Luckily it worked out very well.

Seeing that I have the 3 speed auto as well I have a few noob questions about this mod.

Where does the water come in from on the transmission.
Is the bell housing not sealed where it mounts to the engine.
Where is the dreaded torque converter that throws the water into the transmission located. Is it inside of the transmission housing, or in the bell housing area and it shoots the water through the vent hole in the bell housing?

Can you drill a hole in the outside like your new vent and pressurize it to keep the water from entering in the first place?

Sorry for the noob questions but I am very interested in this mod.

Water comes in from the inspection plate and from where the bellhousing mounts to the motor.

The torque converter sits right on the input shaft you see in the first picture.

Water will usually stay out of the tranny if you keep moving. Its when you get stuck and have to sit when the fluid becomes contaminated.
