HELP! transmission i think

So the past couple days my 04 auto has been giving me problems. while I'm driving it will all of a sudden stop giving power to the rear wheels. Like it's in neutral but the shifter is still in drive. It's at totally random times and it's only happened 3 times. If I stop put in park then back to drive it goes away. Not a huge problem yet but if it happens when I'm crossing traffic Ill be sunk. Any ideas?

Did you check the trans for fluid? Smell it, does it smell burned? Still red? Does the fluid have foam or bubbles? Check for leaks under the Jeep? Not a huge problem? It very well could be just beginning!

Yep, check that it has the proper amount of ATF in it. With the engine and transmission fully warmed up, shift the transmission through all the gears and leave it in Neutral, with the parking brake set. Check the ATF level with the dipstick you'll find on the passenger side near the firewall. While checking it, make sure the ATF is still bright red and doesn't smell burned.

If it is low on ATF, use only ATF+4 to top it off and make sure not to overfill it. Do NOT use a generic ATF, don't even use Mobil-1 ATF which is not the right stuff. ATF+4 is the only correct ATF to use.

Allright. I'll check it again. I checked about a week ago but it wasn't warm.

Yeah...there's nothing in the tranny... This is baffling because it was fine a week/2 weeks ago. There's no oil marks in the driveway but the passenger side under carriage is coated in red juice. Springs shocks tie rod trac bar axle shaft. Por que is happening?

Ya got a leak somewhere, you're going to clean things up and look for its source often until you can find it. Could be a real seal where its output shaft exits the transmission. In the mean time, keep it full until you find the source of the leak.

Can this leak be plugged or sealed? Can you crack a transmission? What usually causes this kinda thing?

Where are the cooling lines on the ti's. Don't they usually run up the passenger side?

They run up the drivers side and cross over to the passenger side under the radiator.

Bugger is empty. How much ATF+4 does she need?

Off the top of my head I believe you need 11 quarts in a stock size pan automatic. Somebody chime in if that's wrong.

Gaskets, cracked cases, loose or detached fluid lines, damaged pan gasket, cracked torque converter hub, or aged seals and gaskets. It is possible that leaks may only occur under specific circumstances such as temperature variations or driving conditions.

Don't let trans fluid get on a very hot surface like your cats or near cat exhaust pipes because the fluid can burn and even cause fire.

I think that would be the entire system. I think just the pan is somewhere around 4-7 quarts when I changed my filter. But as bad as his leak sounds he might need to fill the whole system.

My dip stick was completely dry when I checked it. I'm suprised my tj hasn't exploded.

Check and see what your engine coolant looks like. A radiator dump and low pressure will let the ATF and coolant mix. My wife's WJ is draining as we speak because her radiator went south.

Have a little patience and add the fluid a little at a time. Overfilling it causes huge problems as well. (Blown seals). I wouldn't drive it again til I could figure out where the fluid is going. The fact that it is on the springs and forward components would lead me to believe that it is probably a cooler line. Is there an aftermarket towing cooler on it? If so check it out as well.

No aftermarket cooler. I'm gonna start by powerwashing the underside. Putting six quarts in. Turning it on and having my roomate shift through the gears while I check underneath. I hope it's just a line or hose and not cracked tranny

Just don't overfillit. It is a pain in the a$$ to get the excess out.

Sigh. I'll do 4. Check levels. Then add more. My dipstick has 2 markers on it. One for cold one for hot. Can the cold marker be trusted? This is my first ever work on transmissions so...

This is the reach of the spray or leak.

The last one is looking down so you can see how high up it goes. But ALL that wet stuff is tranny fluid. I put the clamp back on the hose where it's supposed to be and hopefully it will stop.

I'd drop the pan and change the filter ASAP. A full transmission flush is always a great idea if it has over 30K mi on the fluid. You need to find the leak and fix it or you will have a very expensive repair. When you are low on fluid you will burn up the clutches much faster and the filter will need to be changed.

They're pretty bad pictures and don't really help much. But hopefully it's fixed.

See that's the problem. I had a shop do a full flush about 2k ago.
