Tranny temp

I own a 2022 Tacoma double cab TRD Sport 4x4 and I was wondering should I need to know my tranny temp when towing? My truck came with a hitch so my assumption is I have an internal transmission cooler. The truck has several adds for performance. I have an OTT tune, K-N filter, Borla exhaust system, timbren load boosters for the rear and a Redarc brake controller. I have an equalizer hitch setup for our camper. When we retire in a few years we are taking a road-trip across the USA and was wondering should I be monitoring my tranny temp? The gross weight of the trailer is 4000 lbs. Thanks in advance.

 

Up to you.
Your model year does not have an axillary cooler like early models have. Also you are tuned.

 

Short answer, yes.

Scan Gauge II works for me

 

I would!
There is the mentioned Scan Gauge and also you can add an app on your phone and use an OBDII bluetooth dongle. I prefer the latter.

Its never a bad idea to gather information. What you do with that info is the real piece of value though.

 

I have the OBD Fusion app on my phone
I monitor trans temps when towing using a OBD Link MX+

 

like duff said short answer is yes , but if your going to tow a lot then you should upgrade to an extern transmission cooler or simply buy a bigger truck that can handle constant towing

 

I'm looking at the 2022 Tacoma brochure, and it shows ATF cooler and Engine oil cooler are both Standard on all trim levels with automatic transmission.
Not available with manual transmission.

 

they discontinued the external atf cooler sometime in 2020 in tacoma and tundras

 

With the OBD Fusion app, you can use Carplay to connect to your OBD II reader where you can display PIDs on your head unit.

 

Interesting.
I have a cooler installed on my 2023 from the factory.
And the receiver and associated wiring harness.

Are you suggesting the 2020, 2021, 2023 and 2023 brochures are untrue?

 

i would delete that condescending comment lol

 

To clarify, every AT tacoma has AT fluid cooler inside of the engine's radiator. Yearly models with the tow package have an additional AT fluid cooler hooked up to the radiator's AT fluid line on the its side. You can see it on the driver's side of the radiator. Apparently, it was discontinued after 2020.

 

thank you for clarifying, but i did say external .Bgavin click this link it may have more information on that https://www.tacomaworld.com/threads/no-more-trans-cooler.782454/

 

mine doesnt have it , but i dont tow so im not worried

 

Here's a link to an easy way to add an external cooler:

Op, 2020 models and up dont have an external transmission coolers. If this is something you may be worried about you may want to add an external transmission cooler. Keeping an eye on temperature may help as well. Also dont bother checking if its there , its not lol.

 

I'm not being condescending at all, but did change the wording to make you happy and avoid a ban.
Every brochure from 2012 and newer has the exact same wording.
My 2023 has an external cooler installed.

I am questioning your absolute statement, without any proof, that these are discontinued.
I have one installed from the factory, on a 2023/10 production date vehicle.

 

just take my word for it its been talked about plenty of times here on tacoma world , the brochure says there is one but its not .Yet nobody did anything about it just come here and cry about it lol. Also the original comment you did was quoted by me so its still here lol also i said i would delete that condescending comment is because respectfully you sound like a jackass not because you will get banned lmfao

 

Toyota transmissions have been cooled through the main radiator for a very long time. Decades.
This is nothing new, but calling it an ATF cooler in the brochure is very misleading.
Especially when I have all the other towing package components installed at the factory.

So yes, the brochure people are lying.
Pity.
