Need some serious help..

So my CJ was running fine the other day, took it out and trailed, came back home and parked it. Well took it to the car wash the day before yesterday and washed it (no pressure washer) and drove it home and parked it. Got home and had it parked, left the house for about 30 minutes and came home to a puddle of transmission fluid about a foot wide and 3 feet long. Checked oil today, was just fine on levels, but it looked as if the trans fluid was coming out of the top of the tranny/out of the dipstick tube. Now the stupid thing will not start, I have white smoke coming out of the exhaust and a slightly sweet smell coming from the CJ. I also am having smoke come out of my oil fill tube. Any suggestions before it ends up on Craigslist (for real, because I paid way to much for it to have this many issues)

I'm confused over where the oil is coming from - is it transmission oil or engine oil? Don't think your transmission should have a dipstick tube.

Transmission fluid. That's what's leaking.

It sounds like you have a compound problem with different issues causing your symptoms. The transmission problem should be phoned in to a transmission shop that you trust, to get some idea of what that could be. All I can think of is something is plugged up in the normal fluid channels that would make the ATF come out of the dip stick.

The engine sounds like it could be an EGR problem, head gasket problem or worse. Check to see if you can "blow through" the EGR line... to check if it is clear. If it is, and your engine will spin over, running a compression test on her. See how tight she is... maybe its a head gasket. Usually white smoke coming out of an exhaust system is water entering the combustion chamber. Usually this is due to a bad head gasket, which is simple to fix. Pop open your radiator cap and see if you smell gasoline or oil. Do you see any oil residue in the water?

Since your vehicle seems to be a great model jeep, sit back and reexamine why you bought it in the first place. Don't make a hasty decision to sell it based on this because you won't get your money back with these problems at all. These things happen to all jeepers at some point, especially if you buy a used jeep. It happens. It is a jeep thing... no not really. It is buying a used car, having no note and yes, they break down and we have to repair them. That is the price we pay for not having a monthly $400+ note. But think about it... WITH THE MONEY WE SAVE, WE CAN AFFORD TO REPLACE THE ENGINE AND TRANSMISSION EVERY 100,000 MILES AND STILL BE WAY AHEAD OF THE GAME because we don't have a monthly note.

Take care and keep jeepin.

Sometimes a trans can puke fluid into the intake via a modulator valve. This causes white smoke. Pull the mod valve vacuum line and see if it has fluid in it. Below are a few of the things that could cause the overflow.


Overfilled fluid
Plugged vent line
Bad modulator valve
Filter not properly installed
Line clogged to or from cooler
Bad torque converter

Here is where it is leaking. Where are these things that could be causing problems besides the torque converter located?
The first pic is the dipstick tube, and the second is the side that it's going down.

TF727 doesn't have a modulator valve, only the TH400 does. My first thought was the same as yours, till I checked his profile.

78 CJ7.. 258.. TH400/Dana18.. SOA/stock YJ springs.. 35" General Grabbers.. Waggy 44s.. 4.88 gears...Spartan/Lockright...Fiberglass front to rear

So know that I have found out for sure that it's a TF727, with my symptoms I have described, does the current suggested diagnoses stand, or is there more just knowing the transmission that's in it now.

I can't help you much, autos are my weak point. Do have a question. You said it leaked out a pool then you checked it and the level was fine. Did you check the fluid level with the engine running?
If not recheck with it running and I bet your low.

Pull the radiator cap and see what it looks like. The slightly sweet smell and no start would lead me to check for head gasket failure. Why that and the tranny at the same time is way beyond me.

°lllll° Am I broke yet??

Fluid leak from the tranny sounds like a plugged vent. Maybe you got some mud around it. The oil heated up during use, expanded, and vomited out of the dip stick tube... path of least resistance. Better than blowing a seal.

Not much on engines, not much on anything really, but as mentioned, check your radiator for oil in the water... check your engine oil for water. Sounds like your "burning" antifreeze in your engine, hence the white smoke and sweet smell. Unless a cat got into your intake??

But the right word at the right time... "Hey, give me a little hug!" That's the difference between lightning and a harmless lightning bug!
