a little nervous about flushing transmission fluid with all the horror stories you hear, should just dump the fluid and leave it at that? thanks ahead !
recently bought a 2005 tundra w/100000 on it, and the tranny and differential
fluids are all original

It depends on the maint done before you purchased it. If the fluid has never even changed before then there is a good chance you have some sludgy stuff in there. If your clutch stacks are worn and some of that is what is keeping your friction and you change the fluid, you could end up slipping in a few hundred miles.

Tranny fluid has a lot of detergents in it and can break up stuff that may be stuck in places and let the previously stuck debris start circulating.

On the other hand, if it has been regularly maintained then this should not be a problem. It just really depends. Ask a local trans shop, not a mechanic shop. Most mechanics simply outsource transmission work. In a mechanics field it is always good to change fluid on something that may be old/used. With a transmission, this is not always the case.

At 100k I would drop the pan, change the filter/screen and then flush it, of course use only OE fluid. New fluid is not going to destroy your transmission or wash away some "sludge" that is holding your transmission together. Usually damage that occurs after a trans is flushed is caused by a problem that was already there, which is why Joe Shmo decided to get the trans flushed in the first place, or from using the incorrect fluid type.

in 3 years ive only seen one trans go out on a tundra, and that was the owners SC tundra that he beat the piss out of. any other issues have been from customers pulling the trans drain plug when trying to change the oil.
I have personally done dozens of trans flushes on tundras of different mileages and never had an issue with any of them

Dealer did my flush at 40,000 and will do it again between 80-100,000. I worry about it due to stories of people waiting till 90-100,000 to do first one. My other vehicle has a dip stick and is getting drain and fills every 20-30,000 without drama.

That's crazy... These guys wouldn't even change a oil filter after the car been on a hoist lifted... ? Dude the filters is like right there . I am totally blown that there's company out there doing shiet like this.. Sigh.. What a world...

Recently I dropped off my truck to Toyota for a 5k service and ECM update... The 5k service is pretty much a tire rotation and 21pt inspection... When I went to pick up my truck, they told me they did all of the above and extras... I marked the rear tires that were on the rear before dropping it off and it came back the same way where they didn't even rotate my tires... Another word Stealer is the same way as others... Best way to make sure it's done is to do DIY

Glad I have been doing my own work since I am my own mechanic

Well I flushed mine at 75k miles and by 96k miles the tranny quit. Torque caused most of the issues. These trannies have 6 sensors and all 6 had to be replaced. All particles get magnetized and stick to these sensors. The tranny specialist rebuilt my torque and tranny stated never flush. Drop the pan. So I'm up to the mileage to drop the pan and see what I got. Being a sealed tranny you have to have your fluid at 156 degrees to put it in. I was also told they can put it in cold only when tranny is cold.

My understanding is that there is a difference between a power flush and a fluid exchange. Most call a fluid exchange a "flush" also.

I'm coming up on 75k and mine has never been changed. Not happy about that (I bought used); I checked the overflow plug and it wasn't the bright shiny red I was hoping for. Others have noticed the same dark-ish look, so maybe it's nothing. Not sure yet if I will drop the pan or just do a fluid exchange; from what I've read most of the metals come from initial break-in, and then those metal bits stay wherever they stopped, which is why OEM's don't recommend changing the filter anymore.

For me, I'm not sure I want to change the filter, since I'd do it in my dirt driveway and would likely add more dirt to the system than what would be removed.

Not a bad idea. I wonder if a dealer would have all the bits required; filter, pan gasket (?), crush washers. I know there is a DIY here or elsewhere, might be a good weekend to do a fluid change on it (too hot to do anything else).

Is it a real filter, or just a wire mesh? Going to call around, but if it's not a real filter then I'm not sure why it needs to be changed.

I did see it's about $25 on Amazon, though. Cheap enough to replace, assuming the dealer is close to that.

Dealer was around $50
It's an actual filter. It's the black part.

Pricey, but I guess that's what you pay for the "right" part.

Does this use a sealer or is it a regular gasket? I'm still trying to find the how-to that is on some site somewhere, where it shows what transmission line to pull. I'd like to do this job this weekend, and I kinda need to pull the line and pump out the transmission; it's 75k on the original fill so a pan drop, while good, is probably not good enough.

Just a gasket.
Honestly, I didn't need to replace the gasket but just wanted to be safe. I'd spring for the filter though.
Next time I'll try the valvoline maxx life fluid, its half the price of the toyota fluid.
