And what do you think is clogging things? Automatic transmissions aren't going to be clogged by debris from the air. If you're starving the pump, its likely you've shorten the life of it and other parts.

You're undoubtably correct In my oppinion however this gives no ground to say a perfectly operating trans is on it's way out lol. Not my first rodeo with this.

Last time I had a thread similar to this I was told my trans wouldnt even last another 3k miles. I guess by someone on the internet who clearly knew what they were talking about. However that was 15k miles ago and weeks racing on the sand dunes.
Don't you have a problem with the trans pump sounding starved? Indicating that it's not running perfectly?
Ultimately no one else will pay the repercussions of driving around with this problem besides the owner/driver (i.e you). The likelihood of things being excessively worn/damage is high and will probably lead to premature failure. I personally don't like breaking down on the side of the road.

How do you hear the torque converter kicking in and out?

I am watching this thread just to see what the outcome will be as to the actual cause of the transmission noise.
Is it the actual transmission pump? The TC ? The Transmission ready to completely die?
Stay tuned as we found out next time on

A bad TC can last a few years. Amazing.
I have 150,000 miles on my 2005 SR5. The dealer changed the tranny (5 quarts/filter too) at 100,000 miles, and I'm at 150,000 miles now.
Should I drain and fill another 4 quart - and leave it at that.
Tranny gives me no problems.

No they can't. I am not driving it. If they are bad and you continue to drive them. Not only do you have a chance of complete failure. You can seriously damage your transmission. I just am working of 3 of them at the moment and want those completed before I will pull the Transmission out with the bad torque convertor and replace it.
Keep in mind, with the fleet size of Toyota's I have, I only drive 1 or 2 4 runners at any given time. Its my hobby to fix and repair the 3rd gen 4 runners. I wanted to save a few in this area before they were gone as PA is a major rust belt state. :{

Lol!! Well update for you, a new trans filter and solenoids have arrived to my house today. Going to install all three solenoids this weekend along with the filter. (Provided it doesnt look brand new still). I forgot I have a p0770 code because I've literally had a check engine light for this code since I've owned the truck. Figured I might as well swap those out as well. I'm going aftermarket solenoids. Not going to put upwards of 900 dollars in 3 OEM solenoids on this trans when I have an extra in the garage. These solenoids ran me 100 bucks and came with a filter but I'm not using that one I'm going to stick with OEM. Well see!!

The filter is just a metal screen. So if you have a pile of debris in it. Won't be looking good for the tranny. I am curious what the pan magnets look like too.

Does it happen at 18mph as you come to a stop? I've always noticed that with mine since I bought the vehicle at 232K miles, right now I'm at 260K and it's still there. It always happens when the OD is engaged and I'm coming to a stop, I hear a clunk. If the OD is OFF, it never happens so it's something to do with overdrive solenoid or the torque converter disengaging... Very strange.

I'm pulling for the guy but I don't think this ends well.

Exactly I'm not sure what mph it's hard to explain the sound but you know what I'm talking about! Lol

I'm interested as well. This is the mess I dealt with originally.

I completely cleaned the magnets to make them look brand new as well so well see what's going on! Btw I race in 4lo on a sand drag strip at the silver lake sand dunes and this thing kicks ass. I rarely lose unless someone has some crazy mods. Anything stock jeep wise or truck wise I dont lose to. Trans revs out to 5500rpm through all gears no problem. Lol time and time and time and time again. Fun stuff. Parts are a dime a dozen out here I'm not worried about breaking anything. I just dont want to end up on my back in the middle of Michigan winter doing a trans swap in my garage

Well I swapped the filter and all three solenoids and the check engine went off the trans noise went away and it's looking pretty clean! These transmissions are really bulletproof! Magnets were dirty again but no chunks of metal just sludge. The last filter swap did its job and so did the magnets. I'll revisit it again in the spring and if anything flush the fluid and install another filter. Rinse and repeat untill shes clean!

I would be looking for spare trans with lowish miles and never been cracked open. that is a lot of clutch material IMO.
I did not take pics of the pan but... this one 240K miles and never been cracked. fluid was a little black but still had some red in it.
https://www.toyota-4runner.org/3162709-post2.html
the pan had no where near that amount of build up on the magnets.
also? why is the paint missing on the inside of the pan? did that trans endure some crazy high heat?

I know when I cracked open my 98 with 215k on the clock my magnets didn't look that bad. I agree there is a pile of material being gathered. My Transmission was never opened before then and I bought it off the Original owner. My fluid had a tint of red left in it and the metal screen filter was clean.
The OP of this thread has a transmission in his garage so maybe he is testing limits of his current one. I really am not sure.
I was curious as to why the transmission would sound starved for fluid. To me, that sounds like a failing TC or pump going.
Maybe it will last quite a while yet and only time will tell. The way its producing material especially metal this should be interesting.
