Nitro 4.88 gear heat

[TLC2013]

I guess my 2009LX doesn't have an Engine Oil Temperature sensor or PID. Section doesn't have it and 'oil' search doesn't return a match. Looked in the other sections as well.

I have had a heck of a time locating specific PIDs in the OBD Fusion app. Not sure why its search function is such a struggle to use. I have the app on multiple devices but the toyota specific PIDs only work on the device that has the paid add ons. Not sure if this is why you cannot locate it.

You might do a rescan while parked, just to confirm that the PIDs aren't currently being hidden by OBD Fusion (e.g. missed on the original scan, or possibly added to a newer OBD Fusion update later).

I’ll rescan. I did buy the Toyota add on.

Sorry to hijack for a moment but this thread has the folks I'm interested in hearing from and its mostly on topic aside from the fact that I still have factory gears...

Just went for a drive to see what my temps look like and play around with the ODB Fusion app that I've had for years but never really tried.

After about 10 miles on the highway in 106f heat cruising at 75-77MPH these were my temps sitting at the off-ramp stoplight:

After getting back on the highway and driving a few more miles at 75-77MPH...

And a few more miles after that at the exit ramp stoplight...

After driving through the neighborhood and back in my driveway...

So my questions are:

1. Do these temps look relatively normal?
2. What is the difference between the two Trans Temps aside from #2 being highly variable and #1 being more steady?
3. I'm wanting to log my drive to LCDC and overlay the data from ODB Fusion (Speed/RPM/temps/fuel) with GPS (location/altitude/speed/time). Is there value in doing so? If so, what would be the most valuable things to track?

Again sorry for the hijack.

#2 seems to increase with work, #2 seems more steady. That’s my experience. They tend to run 5 to 15 deg different. When it’s just chilling on idle in the driveway those two and the radiator temp converge.
Mine with 4.88s seems to max around 210 deg. But I don’t have any 100+ outside temps to compare with.

Okay, so the variability of #2 in mine didn't seem to be tied directly to vehicle effort, unless its latent by 10-20 seconds. 224.4 was the high point for #2 but it would vary wildly from the same as #1 to between 218-224 on the high side. I don't think I ever saw it below #1. Engine oil and coolant temps over 200 seems worrisome, but the instrument cluster gauge never moved from its normal spot. What would be a worrisome temp for those? I assume for coolant there is a boiling point that is higher than 212?

Also to tie back into the thread, my Trans #1 and Engine oil temps did track with each other to within .5 degrees for the vast majority of the trip.

I don't have any data but wish I was recording this past weekend. Towing and loaded for a long trip for 6, so I was probably laden the heaviest I've ever been. In 115F heat.

She never skips a beat so it would be more out of curiosity.

The AT TEMP 1 looks similar to what I am seeing with my 2013 LC (100,000 miles) with a recent transmission fluid exchange-Amsoil SS. It generally fluctuates between 194-198 on the highway with outside temps between 65-100F. I haven’t noticed much of a change in trans temps in Relation to the outside air temperature (northern CA). Temp 2 should be reflecting the torque converter temp. And I generally see between 195-224 depending on the grade and amount it unlocks/locks. The temp shoots up to 215-224 momentary before dropping down to equal or within 5 degrees of AT temp 1.

I’m in a 2013 LC with 103k, fluid exchanged at about 98k if memory serves, and you describe what I saw exactly. So I’m guessing if #2 is at the torque converter then #1 is at the pan. Thanks!

Cool glad to help. Yes sir, temp 1 is for the pan. i used that reading for the fluid level check (109-118F) when I did the exchange.

yes your temps look reasonable. At2 is the torque converter which heats up quickly. At1 is the pan temp which tells you if the system is able to cool the transmission properly.
