A jeepclub member of the dutch jeepclub had a little accedent last weekend. He drove his TJ in deep water with a ARB snorkel but after a few runs the engine stalled. After inspection they saw that water had run in the auto transmission and boiled the oil out ! end of transmission !
Now my question : I read some write up a time ago on (i think) this forum but i can't find it (search is out).
Does anyone know this problem and the solution or the link to that page ?
HIs only solution will be rebuild the transmission. He can add a longer vent line at that time. I never do the deep water stuff myself (past bottom of the floor boards anyway)
Yes and no... The 3sp autos have the vent in the bell housing with no way to extend it with out welding the hole shut and then tapping a new hole. The manuals I believe though have the breath on top and can easily be extended to avoid this...
I have an auto and until I can find the time to re-locate the breather I avoid water past the middle of tires if possible. A few times on flooded roads I have gone through and has the alxes completely under and the t-case skid at about the water line. If that happens just take it slow to avoid splashing up around the tranny and then flush the fluids...
I think the general consensus is if you have a auto, stay away from deep water and if you have a man, tie your left foot behind your ear to prevent pushing in the clutch while fording it.
I had the same thing happen this summer. Was trail riding and hit a mud hole and the auto trans took in water. It was destroyed by the next day, even after I changed the fluid and filter. (it might have been mentioned already, but water breaks down the friction material and adhesives..
I relocated the vent tube, and had the trans rebuilt, I am now searching for a aftermarket torque converter and not having much luck.
Would love to get this thing back on the road before deer hunting..
The 4spd auto's have the breather up much higher -- pop you hood and look for the auto-trans dipstick... the breather should be in that general area. It's pretty high up. I've read a thread or two that suggested their 4spd breather wasn't in the right place (don't know that for a fact.... going by memory), so do take a few minutes to locate it to confirm.
I've taken mine up to the tops of the tires -- no problems. That's about as high as my personal comfort factor will allow me to go.
I have got water in mine 2 times, did a lot of flushing with ATF +4 and all, is ok now. It takes about $100.00 dollars in oil plus a couple of filters each time.
The snorkel is used in Australia for getting fresher less dusty air from above your Jeep making sure that you air filter lasts a little longer. It also provides protection from water being sucked into the intake of the engine, but is not the only thing that you need to waterproof, like transmissions, diff breathers etc..
Over here in New Zealand, especially the South Island, about 50-75% of Jeeps that go seriously off road have a snorkle as we do lots of river crossings, and while it may only be up to the sill, you never know when you are going to hit a hole, and it is good to know that you can drive through it and out the other side, even if the water is halfway up you doors.
When you install a snorkle it pays to make sure all the joints are sealed. One guy who installs them over here does not let them out of the shop until they stall if you put your hand over the snorkle intake. Then you know it is sealed.
