+1 on ripping the carpet out. I’ve thought about doing this and rhino lining the inside of the cabin floor completely.

In that TJ Wrangler that I mentioned I extended all the breather tubes up the height of the air intake which was essentially the hood line.
I’ve never had a snorkel on any of my vehicles and don’t plan to put one on the JL, but if I needed to use one, I would like to know that my transmission had the same protection. Again, your engine air intake is more critical than the tranny. The transmission breather can be submerge for a short time without pulling in water but if you dunk for the air intake for more than a split second, you are getting water past the air filter and it’s gonna be a long day.
When I extended my breather tubes I just went to the hardware store and bought the same diameter tubing and the fittings needed. I ran the rear diff up the rear of the body tub behind the taillight and the the front diff, tranny, and t-case I run up to the top of the engine bay.
On the JL the transmission breather is up in the engine bay already and the others are high enough for me. I don’t plan on doing more than 30 inches of water in this rig anytime soon.

Thanks for the great info. Any idea where I can find the breathers for the transmission and transfer case? I’ve heard they are on the fire wall behind the engine, but I haven’t been able to find them yet. Thx

I removed the carpet after the first week. I do have the weather mats that cover pretty much everything. Don't be afraid to take a water hose to the interior I did it the first time last summer after a beach trip worked great but kinda scary doing that the first time. Probably not nearly as scary as having to get back in the Jeep with the GF she looks very much non amused

I am not around the Jeep at the moment, but you can find the end of the 8-spd transmission breather tube in the engine bay. See the white cap in the photo below.

The transfer case vent tube does not route that high. If memory serves me correctly, it runs on top of the transfer case and transmission assemblies and ends at the engine bay/firewall. You should be able to get under there and find it (black Hose) coming off the top of the transfer case. The T-case will tolerate water more than the transmission since there are clutch packs and much more electronics in the auto transmission. A small amount of water in the transmission can fry solenoids, pump, and cause the clutch pack adhesive to break down. The T-case is mostly hard parts and a few electronics but still want to change the fluid if you end up getting water in there.

Thanks for the clarification. I have a standard transmission, but I found the breather in the same location as shown in your photo. Nice and safe.

The transfer case, on the other hand, was a bit tougher. After looking all around the transmission tunnel and having no luck, I found this photo of a JL TC on the internet.

It shows the breather at the end of a short hose on the top of the TC (lower center of frame, facing camera).

Armed with this info. I was able to find it on my JLR, and indeed it is at the end of a very short hose. (though it is difficult to see, the breather is in the center of the photo below, facing away from the camera.)

So the transfer case breather is only about 26” off the ground, well below the max fording depth of 30”. I guess I better check the fluid. I just returned from Mojave Road which involved fording water a little deeper than 30”!

After that, put your now dried out carpet back in and roll out.
I did the above probably a dozen times in my old TJ.

Psh. Amateur. I just pulled the carpet out and rhinolined the tub

I'm thinking about doing the same with this one, only I'd put the carpet back in. OP, if you find yourself in water often, you might want to consider that, too.

So would there be any dangers to rinse the engine bay with water if that’s where the breather hole is? Do I need to tape that off before doing an engine bay wash?

I used to throw a dehumidifier in the back of both of my old Jeeps to dry them out after something like that. Let it run over night and your Jeep will be bone dry in the morning.

Hi Onyx, amateur here. What is Rhinoliner? 2 1/2 year Jeep owner. Trying to learn from the masters.

Nah, that cap is a one way valve.
