    Hey all, been a member for a while, just not much of a poster. Anyways, I wanted to see if anyone else has had this issue:

    About 3 months ago I had a very small puddle of transmission fluid show up under my truck in the garage. I assumed this was the start of a seal that has worn out. I cleaned it up and had to leave to work out of town for two weeks. I came home to no new visible leak. I drove the truck when I got home, the next morning an even smaller puddle than the first was under the truck. I cleaned it up that night and had an appointment to have it looked at. Unfortunately it would have to wait until I was back from another work rotation (3 weeks). I came home again and drove the truck and from that point on, I never had any other signs of leaking. No new residue on the underside of the truck. And for the last month I’ve had no sign of any leak( I check nearly everyday)..

    So with that being said, has anyone experienced a tranny leak like this that just started randomly and stopped just as fast? I’m gonna get under her one of these days to get a real close look, just been busy with kids and wife!

    I misdiagnosed the fluid, it ended up being the antifreeze- red in colour and I was used to seeing the old yellow/green stuff from my older vehicles.. so it ended up being a faulty water pump which I had covered under extended warranty thank god! Had all the diff fluids changed over and a full tune up and it’s been running great all year.
    From what I know, the transmission fluid is in a fully sealed system so a leak prob would be a seal of some kind or a cracked tranny case- something like that.

    What's the mileage on your truck? I always like to keep an eye on the stuff I read about.

    2014 with 150,000 kms.. that water pump fix was around 135,000kms. Toyota told me that’s quite rare for them to see. I couldn’t say if that’s totally true- this is my first tundra coming on 3 years of ownership, before that I’ve had 3 Tacoma’s which were hassle free trucks. I’m loving the tundra as well, I don’t see an end in sight!

    I just noticed a couple drips on my skid plate. It’s coming from the trans drain plug. I checked the plug with a 5mm hex key, and it was pretty tight. I tightened it another 1/4 turn, and I’ll keep an eye on it.

    Weird that the drain plug would leak.

    I did add a quart when I installed my external trans cooler, and used the fluid check procedure in the manual to let any excess fluid out.

    My 2010 Tundra had the water pump replaced twice due to leaks.

    Maybe needs a new crush washer? :notsure:

    If you take it out with the truck cold and running you should be able to change the washer with minimal fluid loss.
