    where in hell is refill plug on 07 tundra 6 speed automatic transmission

    • Anonymous says:

      I just did a service on an 07 6 speed 4wd. The refill plug is on the front driver side of the transmission right next to the diff. You’ll need a 15/16 wrench to loosen the plug and you’ll have plenty of room to move the wrench. The one issue I found is actually doing a flush. All I could do was a drain and fill. Just make sure you don’t fill it past 4 quarts.

    How will I change tranmission fluid on toyota tunrda 2003/

  9. robert says:

    I have a 2007 tundra but don’t know where to check the transmission fluid, I look everywhere there’s not even a dip stick.

    I have a 2010 Tundra Double Cab 5.7 V/8. Let the dealer do it as all you can do is a drain a flush. The majoity of the fluid is in the torque converter. I e-mailed Toyota Canada and asked them why there was no dip stick. Their reply was they didn’t want the owner trying to service their vehicles transmission. My reply to them was then why even bother with an oil dip stick. I said it is called piece of mind. You are going on a trip you check your coolant, oil, and automatic transmission fluid level to see where it is at. If any are low you can add or at least find out were it is going. So you are driving along in the summer maybe with a trailer and all of a sudden your trany craps out off warranty to bad so sad. Who ever came up with that idea should be shot with a ball of his own shit!

    • Jim,

      Agree with not having a dipstick. The shooting with a ball, not so much. :)

      I own a 2010 4.6 Tundra and did alot of research before purchasing it. The reason for no dip stick is Toyota went with a sealed unit that helps keep dirt and moisture out. I guess if you dont see trans fluid on the ground your good to go?

        Good luck with no spot-no problem. Have an 03 and the transmission seems to slip when accellerating after going around a curve or slowing at a stop light. The dealer put fluid into it saying it was low and it kind of worked for a while. It’s back to slipping again but I dtill don’t have a spot on the ground. No one has an answer as to where it’s going… Aliens I say.

        Correction on the year: 2007 Limited. I’ve been working on my 03 corolla the past few days…

    I can’t find the damn dip stick either. Now I know I’m not nuts. Checked my oil and all the other fluids but feel at a loss not to check the transmission fluid on my 2012 Tundra 5.7 liter, 8 cylinder monster. Seems like I can check it on lesser vehicles that don’t haul major loads and get very hot. I like the dipstick idea and the shit shooting ball idea.
    I’ll quit looking for the magic want now and just find solace in knowing that some really major oversight in design has occurred. Kinda like not having an integrated towing system from the inside.
    Nice truck though.

    I drained my transmission fluid instead of the oil and must replace my transmission fluid. I can’t locate where to put it into. I’ve researched 2008 Toyota Tundra engine diagrams and can’t find anything on it. If and when I do find it how will I be able to check the level?

    • Chris says:

      cole, I just did the same thing and feel like a dumb ass. did you find out where to fill is for the tranny fluid?

    • Anonymous says:

      I did the same thing, thinking that the tranny pan was the oil pan. Caught the mistake when I saw that the fluid was slightly red and after I had drained about a quart. Took this damn lovely-but-stoopid machine to my local mechanic who quickly put her up on his lift and added close to 2 quarts. On my 2006 “limited”, 4.7 model, the pan had a bolt in it(looks like the bolt for the oil pan) thus my mistake. A few inches away from this “drain” bolt, there is a plug. Must remove with an Allen wrench. This is (I guess) the check/fill spot. I was told that you must remove this “plug” and if fluid drips out you are OK. If not, you add fluid with a special hose and fitting until it does. The vehicle must be level and the fluid thoroughly warm when you check. Toyota and some shops seem to make this process unnecessarily complicated. You’re supposed to take the temperature of the fluid with a special tool and use ONLY TOYOTA WS fluid. Again, seems like they don’t want anyone but a Toyota dealer to do the general service that most of us prefer to do ourselves. Comes down to mo-money I’m guessing.

    I have a haynes manual that says the oil capacity for filter change is 2.2 quarts. not so, i drained 3.8 quarts from the pan

  14. Rod says:

    Sorry, I was trying to add a couple pictures, because I just did a simple drain/refill on my 2010 Tundra.
