Normal A10 Transmission Temperatures?

[MAT1955]

@AZ_Ryan .....I respectfully disagree. I have installed many small transmission coolers over the years. Even a small one makes a tremendous difference and new ones are even more efficient.

Thought about that but I don’t seem to be exhibiting any signs that it would be low. Shifts aren’t jerky etc. Anything else I should look for?

My point is, I don't think your temps are crazy high. And you do admit to hard pulls with Paddles. Increased temps are expected under those conditions. Especially in traffic.

Maybe someone with the performance pack can chime in and share their temps.

Okay thanks for clarifying.

I will try to explain the setup as best I can after inspecting it on my PP. I will reference the photos below.

Photo 1: The transmission cooler is shown with green and red labels in front of the pan. This cooler is the part that is the same on the PP as the non-PP. On the PP the lines on the left and right labeled aux cooler run to the front of the car where the aux cooler is located. On non-PP cars the line on the right runs back into the cooler on the left side where it is labeled aux cooler.

The center two lines labeled radiator run to the radiator on both the PP and non-PP cars.

Photo 2: This shows where the two center lines running to the radiator are located right behind the radiator fan as well as the lines running to the auxiliary cooler.

Photo 3: The auxiliary transmission cooler sandwiched between the radiator (rear) and a/c condenser (front).

Photo 4: Driver’s side of the radiator where the cooling lines connect.

Hopefully that is helpful for someone. It was interesting to me if nothing else.

My PP has gotten up to 221 on the track.

So the non pp could fit the aux cooler?

It looks like it could be possible, but it would definitely be a pain to install. It would definitely be easier with an aftermarket cooler mounted somewhere other than between the radiator and condenser.

@krisk ..... great pictures , very interesting. Thank you! Awesome beast! @TheGrabberBlueGT2024 ..... I agree with @krisk ..... would be very hard to install an aux oil cooler there. Much easier up front and likely more of a radiator function (air blowing through the fins) than a heat sink type tucked in the body cavity. You could run sone ss braided hose, even if you had to have it custom made, that would not be that expensive.

@krisk and @TheGrabberBlueGT2024 Blue .....was discussing this with a friend who owns a 2024GT. He asked, " Doesn't the DH have an auxiliary cooler behind its lower front grille? That area of the grille seems to have OEM open slots to let the air blow through when underway. Couldn't 1/2 or 3/4 inch holes be drilled through it and the aux cooler mounted behind the grille in that area.?"

Was ambient temperature a little lower than intake temperature ? aka a warm day.

230F is fine for engine oil, however 17psi is a little on the low side for what i assume is idle.
Mine (still on factory oil, about to be changed after first 6 months) sits at 28-29psi hot (205f) idle.

Pressure does drop significantly with temperature but that seems like a lot.

Yes it was a warm day. Car was in park when I took the photo I can’t remember if I shut it off before I took it or not but was definitely in park. I’m not sure about the pressure everything I have read varies I’ve seen as low as 14 all the way up to 30 and every number in between with 20 being a common number. I’ll have to pay attention to that later today.

Thanks for the pics. So essentially there is an aux cool in front of the radiator in the PP.

To the OP - I could see that being helpful on the track. But im still not convinced it would significantly lower temps in stop and go traffic. Id think you'd need consistant airflow to get real cooling benefits.

Good to know. That's a bit higher than I would have guessed, But seems reasonable given the driving conditions.

@TheGrabberBlueGT2024

I'd encourage you to monitor your trans temps during NORMAL driving conditions to get a base line and report back. They should be 205-215 fully warm.

After that, do some pulls and use the Paddles. When your temps go up, go back to normal driving for while and see if they drop back down.

If normal temps are in the 205-215 range, and the 230 temps come back down after hard driving, I wouldn't be concerned. If however, you are seeing consistent temps near 230, then I would bring it to the dealer and have them check the system. Yes, low fluid fill will cause high temps. Just because it's shifting normal doesn't mean the fill can't be a little low.

Report back and let us know!

I wonder where it's located.

Behind the grill of the rear bumper, you can see it from the underneath (the guy showed it to me at my recent oil change).
