Tranny oil for analysis

I'm thinking of sending my transmission oil for analysis. Has anyone here done this before? Which company did you use?

Thanks

 

Most folks like to use Blackstone

 

What mileage and what are you looking for?

 

I would venture that is an extremely rare occurrence on fancy vehicles much less a plebian truck.

Blackstone is pretty much the go to. Let us know results if you do it. Including mileage and how the truck has been used.

 

12k only. I feel something could be wrong with the transmission because when I let go of the gas pedal, I sometimes feel a slight shudder and hear a clunking noise coming from under the truck. It feels like gears that disengage abruptly. It happens on and off at slow and higher speed like maybe 40mph.
I have read that some taco's come with little transmission oil from factory. I also spoke to a guy at a gas station with his tacoma having transmission replaced at 30k miles.

 

Profile is bare. Year and model of truck?

Still in warranty?

Some models came underfilled from factory. Some trucks benefit from a transmission TSB. Some trucks act oddly and only improve with a tune. I'd wager a replacement is a pretty rare thing.

Doubtful a fluid analysis will tell you anything.

....^^^... FWIW .. Trans went out at 500 miles on my 2007 Tundra (IIRC, that was a new model year) and Toyota Corp and dealer treated me like a VIP
at Atlanta Toyota. Shipped new trans, nice rental car and free Toyota Platinum Warranty and had truck back in 4 or 5 days.

^^^ This is another reason I am loyal to Toyota.

Just not happy today with the price gouging from SET and dealers now.

 

Mine is a 2023 TRD OR bought new. My thinking is maybe IF the transmission fluid is underfilled, there might be excessive metal shavings?

 

You're in warranty. Use it.

 

The test is gonna come back telling you "congratulations, Betsy passed with flying colors.."
Why not just check the tranny fluid, You don't even need a jack..

 

I'm scared with the transmission fluid because it needs the jumper thing in the OBD2 and needs to be heated up.

 

The two companies I use are blackstone and caterpillar

I like regular oil analysis. Not a Toyota but it got a buddy of mines $50,000 motor rebuilt under warranty. Oil analysis showed metals trending up over oil changes, turned out the oil pump had shit the bed and wasn’t lubricating 3 of 6 cylinders properly.

company tried blaming it on the oil quality or maintenance intervals but the samples were good paperwork to prove that wasn’t the issue

without oil analysis they would’ve fought him tooth and nail and the issue likely wouldn’t have been caught until he was out of warranty

I’ve sent diff fluid, trans oil, transfer case oil, and engine oil to blackstone

I’ve sent coolant and oil to cat

 

Underfill trainny is TW myph.
1st drain in my case and others was 3 q
Other 2 I did after where barely 2.5 q. Even though the level was adjusted

 

I've only ever sent engine oil for testing. I use blackstone labratories

 

Seriously?
Go check your damn fluid and stop giving yourself anxiety.

 

Get an ODB dongle and OBD reader app to see temps on your phone. That’s how I do it. Much easier than the jumper method.

 

This.
I read the newer Tacomas don't need to do the jumper bit, just the shifting bit?

 

Lol its trans fluid, drain some out if it smells like burnt ass then its bad. Thats how you analyze atf. if none trickles out when you pull the plug it was under filled....take it to the dealer and tell them your 2 year old truck with almost no miles on it has what feels like a converter shudder and go from there.

 

If you don't trust your own skills, or the dealer you'd use for warranty work, find a reputable independent shop.
