3rd Generation Transmission Fluid temperature

I bought a OBDS2 BT device W/ Torque Pro
I need some accurate Trans Fluid Temp formulas so I can do a fluid fill

they always seem to match ECT Temp

How do you plan on filling your transmission? I have a 2011 and I took mine to the Toyota dealer for my transmission service.

You fill the ATF via the fill plug.

I would try the PIDs used on other toyota vehicles. Search forum for 21D9 or 2182
Most issues with PID programming is typos

If it doesnt work, get techstream online or ebay

So many trolls so little time

From my understanding you need a gauge that determines the fill level for a certain transmission model to ascertain the proper drip parameter from the plug on the bottom.

No gauge is needed. ATF temp is needed.

I think this gauge is only needed if your trans fluid temp is outside the 104 to 113 degrees F range.
Dealer would use this gauge if a customer brought in a vehicle with the trans at normal operating temp and dealer wanted to do the job right away without waiting for the trans fluid temp to drop back into the 104 to 113 degrees F range.

1994 Camry XLE V6, 1MZ-FE, JVIN, 241K
1991 Nissan Pathfinder KC Truck, KA24E, 5S/MT, 148K

From the video I watched and the service bulletin I read it is used in conjunction with the proper fluid temperature. It is adjustable for various transmission models.

That is the dealer can't wait level check, as mentioned.

The transmission pan already has a 'gauge' or 'straw' calibrated for the previous 104-113F temp already mentioned.

It takes 8hrs for ATF to cool enough for the original ATF level check temp. Dealer can't wait that long with customer in waiting room so Toyota created a super hot ATF level check tool(variable straw for the different RWD and RWD transmissions).

So, ANYONE can check their transmission fluid level with a temperature gauge, if starting from a COLD TRANSMISSION.

If starting with a cold engine and transmission, anyone can check the fluid temperature after starting the engine using even a simple digital kitchen meat thermometer. When the fluid reaches 104 degrees procede with the fluid level checking procedure described in the first 3 minutes of this video:
