    Long story short, I drained my transmission fluid instead of my engine oil during, what I thought, was a routine oil change. Shortly after realizing I had drained the wrong pan (my engine oil levels didn't drop like they were supposed to, and I noticed the "oil" I drained was cherry red and smelled rather appealing, much like autozone) I corrected the problem and changed my oil regularly. The engine oil has since been changed and all of that is peachy. My only issue? Putting the tranny fluid I drained, back into the truck. I have been browsing forum after forum and I have learned that there is no fluid dipstick for the transmission and that it cannot be filled that way because the transmission is sealed. So, it occurred to me that I had to fill it with a pump from the underneath. That would be fine, if I could locate the fill plug. Every DIY instructional video is either for a Tacoma, a 5.7L 2010 Tundra, or an earlier model with a tranny dip stick (or any combination of unhelpful models and years). It seems no one owns a 2008 4.7L V8 Tundra. I really just want to get the truck moving again, so if someone could tell me how to locate the fill plug and what tools I would need, it would be greatly appreciated. Thanks much. -Josh

    yep bank account is running low from it..
    1. Get under the truck.
    2. Look at the transmission where you drained it now.
    3. Look on the passenger(if my memory is right) side. You will see a plug about 3/4 the way up. You will need a allan key to open the plug. I want to say its 3/4 inch or 14 mm allan key you need to open it up.
    4. Replace the oil with fresh oil not from the pan... oil in the pan is now contaminated. Fluid should be just to the fill hole.
    5. Tighten everything back up drive for 5 to 10 miles confirm no leaks. Job done.

    Thank you for your advice, I'll give it a go tomorrow and repost to give you an update on my progress. I hadn't checked the passenger side at all because I was told it was drivers. Kind of dark out right now. Thank you much.
