    Interesting info. I had just been thinking "what should gently used transmission fluid look like? That could be perfectly fine."

    Just another vote to send a sample off to Blackstone. It may show the fluid is perfectly fine and you can extend your oil changes to more than a year.

    Or it can prove your annual plan is appropriate. Either way, lab analysis is a win

    I was being a bit of a smartass, sounds to me like we're on the same page. We're arguing semantics at this point.

    I could not agree with you more on oiled air filters, I too bite my tongue on that one.

    What I meant about pressure drop, is that filter area also comes into account, which is why more drop does not equal better filtration. Yes PD pumps are much more forgiving, but there are other consequences to starving the suction, while collapse on the suction side is possible, shearing the drive due to overload or running out of power are not. Power usage goes down as flow goes down, which is what would happen if the suction was starved.

    Funny you mention a PD vacuum pump, how about that PD air pump you have under your hood?

    But...there is a third possibility. Won't know until one of you guys sends off a sample: :eek:

    There was one member who sent a sample in for analysis. I don’t remember who it was or all of the details, but he had a 2019 or newer and the results he got showed the oil was still fine and he had done a fair amount of towing.

    It was Greg marmaland or something like that. His thread derailed like this one started to do and he asked for his account to be deleted, which also removed the thread he started.

    This is the right method to flush a transmission. Machine flush is not ok. I probably should have mentioned this in my reply for earlier.

    I too believe there's some missing steps, but this is basically what my mechanic did for my previous Tacomas. Basically pour new fluid as the old one is displaced by the engine, so maybe something like 5-10% of the old stuff is still mixed in with the new.

    You made some assumptions. First, the pan, it can be removed without issue with the correct tools. Replacing the strainer and cleaning magnets with a full fluid type change is desirable. Additionally it provides a visual verification that the transmission is healthy before changing, good for business. Second, that overfilling the pan to pump out is bad, is it? States he has been doing that for 20+ years no issue in a different video, I have seen others using the same method. Third, that the pan was run down to breaking pump suction, it was not, the fluid starts sputtering/spitting immediately. If he had run it down to breaking suction, it’s not going to blow up instantly, shut off and add some fluid. I think checking the temperature any other way than using the built in check mode is dumb, but don’t doubt the way he did it is fine. Worked as a mechanic and have a few friends that are. All have their own hacks and work-arounds to be more efficient. I see no issue with the completed job, other than the switching to Amsoil lol. FWIW not how I would do it, take it to my local independent Toyota master tech, easy.

    Thankfully Toyota doesn’t use an Allison 1000 transmission. Internal and external filters...people’s heads would explode.

    They make conversion kits for the swap.

    It’s Cummins, not Cummings. You can always tell the members that watch porn on their devises...:rofl:





    Mine autocorrects to Cummings too.

    I don't know why I keep reading theses transmission threads, well, other than the epic derails.

    I think I have decided to never touch the trans on my 2014. No flush, no drain and fill, no new filter, no nothing, although I do at least have the factory cooler. :crapstorm:

    Good Lord, I hope not. Need to save money for fuel.
    Listen, if I want to watch Whitney Cummings do unspeakable things to herself I dont think there's anything wrong with that.

    She must be very devout what with yelling "Oh God!" constantly.

    Do you have anything to back up your statements about your claims on changing fluid to soon? I’m open to learn something new and for the reason I’m asking. I have learned more off this site than I have taught....

    This was my fluid in my Lexus. I’m pretty sure the 60k mike service wasn’t done and this is what came out at 130k miles.

    32E33369-B9D0-49EF-9B7A-15A56BACDD11.jpg

    The sludge on the bottom of the pan was concerning...AMSOIL went in. I will perform this again in a few months to flush even more out.

    I had a good friend that owned a transmission shop in Texas for 38 years. He was our “go to” guy on a Dodge Cummins forum I helped moderate. I trusted Tim (now passed) and his integrity was never in question.

    We talked about flushing machines. There are a few that are legit, but very expensive. Even he didn’t want to afford one. He would say “toilets are for flushing...transmissions get serviced.” Most flushing machines are crap.

    Tim told us, “if you want a transmission to last in the HD world, drain and fill every 20k miles or so.” His customers were mostly ranchers that overloaded and worked their trucks in the Texas heat. He rarely had failures on stock trucks. He would even pull transmissions and check high mileage ones just for fun (with owners permission) to see how things looked. The ones that Serviced more often had longer lasting units. He even showed his customers how to change the fluid themselves to make it cheaper. Most of them still had his shop do it anyway.

    I’m at 64k miles on my Allison 1000. I should have done one external filter change with one drain and fill at 50k miles. I just performed my second external screw on filter change, drain and fill, and first internal filter (this is supposed to be performed at 90k). This has cost me 150.00 extra in maintenance to keep my fluid fresh.

    Pro tip:
    Instead of using the slippery Pete or similar pump and pumping in a quart at a time, use a 6ft length on plastic hose from the engine compartment and stick it into the side of the transmission at the fill. Attach a funnel to the plastic hose then pour in your premeasured WS fluid.

    I did a drain and fill just like the OP. Only change was I did mine at 60k per the manual. I don’t tow everyday but do regularly. Drained just under 4qts

    I serviced my Allison every 30, spin on with a drain and refill. I sold her last year with 188K on the clock and she is still going strong. I see it every day because my neighbor bought it. LBZ is THE GOAT ! There is a guy on the chevy diesel forums, Allison trans whisperer and he preaches drain and refill only. IT WORKS

    Here's another option, worked awesome. I cleaned it out first and put an inline filter in the hose, flushing some through first before filling, and would recommend doing the same. Also marked the side with a permanent marker as I dumped each quart in, that way you know how much you're putting back in the tranny.

    I'm at 131k miles and have owned it for the last 15k, with no hard record of a transmission service. Thanks for all the info in this thread, i think a drain and fill is in order.

    Same method works on hard to access front differentials. Run a hose or PEX line down the front of the engine and into the Diff Fill Hole. Put a funnel on and fill using gravity.

    The Slippery Pete pump actually came with a few different lengths so I actually ended up pumping it in from the gallon jug. I wouldn't mind doing it the other way if I had someone under making sure the hose didn't fall out though.

    I used to know a couple engineers worked for Hydro-matic (OEM supplier to GM and BMW). They said changing fluid more often than 50K miles can cause excessive wear. There are economy of scales between transmission fluid properties and sludge. Transmission bands wear, they wear faster with new fluid. Again if the fluid has 200K miles than your clutches may be ok but all your passages will be plugged and solenoids will not operate smoothly. I changed fluid at 50K, fluid and pan looked perfect. Flushed at 100K miles (waste of money should have just drained and refilled). My Lexus with 175K miles pan was spotless, I never changed just drained and refilled with two quarts every 60K miles as specified. Last transmission failure I had was a 1997 Bonneville, dealer replaced 5 transmissions under the 3 year 50K mile warranty. Good news, the was the last domestic I owned until 2017 F250. Oh that was the last transmission failure I ever had also....

    Transmission don't have combustion by-products that motor oil has to digest, for all practical purposes the only contaminate transmission see is internal wear, sure there is a breather but it supplies minimal contaminants. I won't change my for 100K miles, someone needs to change their fluid every 2500 miles. We can see who transmission makes it to 200K.
