Transmission cooler?

[KingLamoni]

I think I know what they mean here. Certain regions got smaller trans coolers (5 row), the US got the bigger one (7 row). In my region we got the smaller one which puzzles me because it is extremely hot were I am. Anyways, I think they had the smaller one and just upgraded to the bigger one.

But when you look up the oem part number it doesn't show different numbers. How do you account for that in your theory?

You probably selected the US model somewhere along the line.. So they're showing you US parts.

We know there are differences to the core support, bumper support and crash bar between different regions. My assumption is those differences impacted the space available for the trans cooler, so they made a smaller one to fit everything within the same space.
As usual, a larger one probably fits just fine, that just didn't jive with their factory assembly plan or other constraints they were worried about.

As for trans cooling, the cooler has a thermostat built into it. The US cooler is quite large - I've never seen a larger unit outside of dedicated race or heavy duty offroad stuff. There's no OEM monitoring of trans temp, and I haven't easily found it via CAN/OBD tools, so there's no telling what the trans temp really is. That said, I'd be surprised if it's really a problem for anything other than repeated hot laps. But, would have to add a sensor to the pan or hack out whatever PID actually has that info.

As for engine oil cooling, it uses a coolant-to-oil exchanger. This is a good approach because it quickly heats up the oil when the engine starts. You need oil warmed up so it thins out. The bad thing is this type of cooler will tie oil temp to coolant temp, and the engine coolant will fluctuate between 200 and 220. This cooler is pretty small (4" cubed?) so it can also get saturated such that they can't get the oil down to coolant temp.
HOWEVER, any quality synthetic oil is perfectly happy at 220. It's actually important to get oil above 200 to burn off water and contaminants. Synthetic is totally safe up to a stable temp of 250 or so.
Yeah, the "oil" monitor on the dash is engine oil.

SO, Kazz got his car thoroughly warmed up, but doesn't seem, to me, that he was pushing any envelopes.

I've been enjoying occasional track day events with my 2018 GT2 in the hot state of Florida. Oil temperatures have been OK but the transmission temperature gets a little crazy after 10-15 minutes. What options are out there for an upgrade to the transmission cooler?

How do you know your trans temp is getting hot? What is "a little crazy"?

My Lap3 v2.5 has an app that shows all sorts of sensor readings, including trans oil temp. The track was hot this weekend and the TOT started getting into the upper 200’s. So, I’m in the market to put on a cooler that will perform better than the stock unit.

I know this is an old post but:

BMS Transmission Oil Cooler for 2018+ Kia Stinger & Genesis G70 3.3T *** CLOSE OUT SALE***

Everyone knows that heat is the enemy of your automatic transmission. This heavy-duty trans cooler dramatically reduces transmission temperature, gives better transmission performance, and extends the life of your transmission.

The BMS trans cooler item description says it's a PNP kit ... wondering how PNP the install this cooler is? Do I need to drill holes to attach the brackets? Anyone installed this on their GT1/2? Can the BMS rep chime in?

Thanks

its PNP if you don't have the mishi intercooler. It replaces the stock trans cooler.
oh and also forget about even running it if you have the wagner intercooler.

Okay; before the BMS trans cooler gets installed, the OEM factory trans cooler has to be pulled out? Then, does it fit in place where the factory OEM cooler goes with just the factory bolts and fasteners?

In the photographs, it seems like the BMS trans cooler sits way up front on the right with it's own brackets and fasteners. One of my specific question was, how the BMS brackets are attached, do new holes have to be drilled out to accommodate the brackets? Can they be spot welded? The BMS item description is vague.

Good catch, typo.

No new holes. Existing bolt holes are used and all screws and hardware is provided. The factory bolts and holes for the oem cooler are not used. There is a lot of unused bolt holes in the front radiator support for some reason.

Ah, that makes more sense. It's interesting - I'm starting to think of my Stinger as a 4-door Corrado. Just wish it had a rear wiper..

Yeah, I bought a used Corrado in '97, still miss that car with the goofy seat belt rails that went around the window frame.

Thanks General!

Just waiting on Fedex to drop mine of. Once again it got delayed on a Friday delivery and I have to wait till tomorrow for it. Installation looks pretty straight forward, though the rad will have to be filled with ATF before its installed since our transmissions are sealed.
