I have a 2004 GX470 with 130K on it (sealed transmission). Last week I was changing a lightbulb and noticed some of my transmission lines had oil on them. I followed them back and it looks like the lines are weeping transmission fluid at the connection points with the lines.
I was wondering if anyone has had this problem and if so, could you point me in the direction of replacement hoses. I looked online but am not sure what they would be called.
There are two lines that are about $40 each for the factory part thru Lexus.Below is a diagram with the lines highlighted.Hope it helps.The leak could be from fittings,o-rings,or from the hoses attached to the lines,so,make sure you identify where the weeping fluid is coming from.
Thank you for this!
This is a huge help. I think most of the weeping is coming from where the rubber lines meet up with the metal lines. But this gives me an idea of what the whole system looks like and how many lines I should replace.

I had same leaks at the hoses [ there factory rubber hoses ] Had to replace them problem solved.
Awesome. What kind of lines did you replace them with? Did you buy new OEM or aftermarket?
Truck was bought used with extended warranty lexus paid for it . The service tech told me that any rubber hose would work but lexus has a part number for it. they use rubber to absorb vibration so metal joints wont break. The factory part is made so it is plug and play I guess aftermarket or autozone hose would have to be cut. its held on with regular clamps

How many miles did you have when you replaced the rubber hoses and did you replace the clamps as well?
I am trying to track down some rubber transmission hoses that are not from Lexus parts. I priced out all the hoses I'd need from my dealership and it was well over $300. So, I am trying to figure out if there is a cheaper way to go.
Does anyone know the rubber hose diameter and what temperature they are rated for? I asked my dealership for this information and they did not know. I would just take the hose off and check but I don't want to take it off before I'm ready to start the service.
Thanks again for your help!
Hoses I am looking at.

Thats a crazy price for rubber hose.Do you have a tool to measure the diameter of the trans line themselves? I do not know if they carry a rating for heat,thats a good question. Is there a transmission shop or a shop that makes hydraulic hoses near you? A trans shop could at least tell you if you need temperature rated hose.Let us know how you make out.

You could try pricing them out on Partsouq and see how much better that is for OEM parts. Do you have a written quote from the dealer that has the full part #'s on it?
I have been working on this problem for a good month now and have an update. After looking everywhere for the specs on the rubber hoses and being too cheap to spend over $300 on new ones, I came up with a temporary DIY solution.
I went to Home Depot and bought new hose clamps that can be tightened with a screwdriver. I replaced all of the OEM clamps on the hoses and so far there has not been any more weeping from the lines. I am going to drive it another week to make sure this is a solution and then take it to a shop to have the trans fluid replaced.
