I ended up paying 50%, $695.95 at the dealer to fix the issue. It was a poor fit of the sealer. I believe Toyota is well aware of the issue and applied the fix for a newer model. I have 70K miles on it, ad may be the one of the few got into the trouble earlier. Toyota flat denied to pay in full, nor process the recall. If you have 2004-2006 Highlander, please be aware. They will get you for $2000 price tag that should been a recall item.
#124 of 315 Transmission Leak?
Aug 10, 2008 (2:34 pm)
I have a 2004 highlander (FWD). I noticed a fluid leak that was below the drivers side below the headlight. When I first looked under the hood it appeared to be coming from a small diameter hose that leads from the radiator, travels along the front of the car to a small cooler housing.
Today I took a closer look and the fluid is transmission fluid, the leak only appears to be coming from the noted hose, but is most likely leaking onto that hose.
Anyway, it's a tight working area and impossible for me to see for sure where the leak is coming from, but it appears to be in the area of the cooler box (if that's what that is). This box I am referring to is about 1 foot or a little longer below the drivers side headlights.
A few questions:
1) Is anyone familiar with this area of the car and the problem?
2) Am I looking at major repair? I would attempt to do it, but I can't get to the area to see what I am doing. I did consider taking out the wheel well cover, but not sure if that will give me access.
3) Is there a free repair manual around here so I can see what exactly is this box?
I took the battery out and the battery tray to get a better look today and it's either coming from the tube/hose that connects the cooler to the transmission or coming from somewhere on the box.
After I reinstalled the battery and added some fluid I started up the car and ran it for a few minutes. When I turned it off there were large drops of fluid dripping down at a rate of a sizable drop every 3 to 5 seconds.

if it is transmission fluid (reddish and oily to the touch), this is probably the cooler line from the transmission to the cooler (either within the main radiator or a separate radiator-looking cooler). It may that just tightening the connection at one end would fix it, or it may be (more likely) that the hose/tube is damaged, in which case it will need to be replaced. You'll need to locate the EXACT point of leakage. Clean the entire hose and see if can find the origination. Remember, things drip down, not up.
Depending on your comfort level, replacing the hose may be simple. Or not.

It's difficult to tell where it's coming from. It is in such a tight area that viewing it from below would be difficult since it would result in fluid in the eyes (not a good thing) and from above you can't see the underside. It also appears that it is dripping onto one of the hoses, so that doesn't help to pinpoint the location.
I thought about removing the wheel well shield and accessing it from there, but I have to make sure that it actually can be seen and reached from that approach. It appears that two lines are going to this "mini cooler", one from the transmission and one from the radiator.
I would attempt to do it myself, but it is a timing thing since my wife needs the car for work. Tomorrow she will use my son's car, but I don't have the time to fix it. So now my concern is getting ripped off by a mechanic.
Anyway, thanks for your input. I wish I could locate a diagram of this part of the car, but I've come up empty.

This sounds very much like a damaged or leaky transmission oil cooler line like others have suggested.
Aug 11, 2008 (4:38 pm)
And that is what it ended up being. The line that runs from the transmission to the cooler had a rusted clamp and that's where it was leaking. A guy that works where my wife works came over and fixed it.
Now I find out that you can't get the transmission fluid at any of the local stores, you have to buy it through Toyota. So it will have to sit until tomorrow.
Thanks for the help, it saved me a lot of money - I owe all of you a beer.

yes, you can get the fluid at a decent auto parts store, Toyotas are pretty popular! But if you want to wait to get it at the dealer, that will work fine.
glad we can help. Pay it forward.
#131 of 315 Toyota Highlander 2003 Transmission problems
Sep 27, 2008 (7:27 pm)
I have a 2003 Toyota Highlander 4WD and I have serious problems with the transmission. When I shift from Park to Revere it does not turn it on, it just goes to neutral. Also, when driving, it tries to shift but it just kicks out and the car won't accelerate. Please help. I tried everything, replaced the PCM, took apart and put back the transmission and found no problems with it. Anybody know what it might be?
