transmission cooler
transmission cooler Here is an update to the thread I started about the transmission cooler I installed. The original thread is here.

Well this cooler probably works a little too well, probably best for much hotter climates. I installed inline with the radiator cooler. The trans temp never got over 186 degrees all summer long, even sitting in traffic jams on 95 degree days. I drive all the time with the DIC reading transmission temp and have been monitoring it since March. It is getting cold here in the mornings, got frost on the pumpkins
. When I left the house this morning it was 35 degrees. I have a 45 minute commute consisting of 40% highway and 60 % back roads with lots of hills and lights. When I arrived to work the transmission temp was 118 degrees, that is far too cool for sure. I let it idle to be sure when I got here and within 10 minutes it was over 150 degrees. I don't recommend a cooler of this size for colder weather areas. Hopefully I can find something for winter soon as I don't want to put this car or this transmission thru another winter. Just a follow up and an FYI for anyone contemplating a cooler. Read the older thread for any details needed. Thanks

Your running a synthetic fluid in your trans. So viscosity isn't a factor when it comes down to it. Nobody has ever reported a failure from cold fluid Temps with dex 6 in there tranission
Having the fluid under operating temp causes the same issues if your engine was running at 118* all the time. There are parameters in the trans ECU that change the way the trans shifts and when the lockup engages according to the temperature of the fluid. That's even evident in the tune files on hptuners. Make sure your trans fluid can always reach 150+.
Apples and oranges. Engine operating temp a whole diffrent animal. Your trans tables increase pressure anyway when cold, aND that's only till 111 degrees anywway. Tcc lockup only locks based on speed but I have heard a minimum of 89 degrees must be achieved for it to all work

I guess I will let this thing warm up in the morning for awhile until I find my winter car. This trans I am not worried about as its on its last leg. Once the new trans goes in it will be done with its daily driving duties anyway. Thanks for the info, appreciated as always.

That's why I used the b&m cooler, it's the biggest super cooler that's minimal size with the inline function where it keeps the trans temps cool, but it never drops under the temp where it'll be "too cool" for your car. I don't think the Hayden has that feature.
I have heard of the valved coolers that use tstats to open and close but I didnt think the B&M's had that function.
