6.2L / 6L80/85e owners

Have you noticed how hot these transmissions run? Typically around 200degs in traffic or hotter. Mine runs about 187deg during a long trip down the hiway. Last trip was to Laredo, averaged about 185degs back and forth.
When they first came out, we stuck a couple BM coolers between the radiator and ac condensor. We noticed a huge drop in transmission temperature.
We also bypassed the transmission cooler embedded in the radiator.

After the installation, we've noticed 130-140degs transmission temps on the highway and most of the racers can now hotlap their trucks non stop with no heat issues.
One customer just reported his trans temps won't get above 180degs after 15 consecutive laps down the track.

The trans temp will get even hotter after a higher stall converter is added.

I realized trans temps need to be brought up to operating temps, but we haven't seen any negative effects after making them run a lot cooler.

Just an fyi, later,

yea ive noticed mine hits 210-215 after 2 runs at sar shootout..sucked.......and i have the biggest hayden cooler

if you're having heat issues with the trans, or it getting up to temp too fast or over 200degs (which is normal), get two B&M coolers on there.
The model with 1/2" in and out fittings, the largest one.
They may be physically smaller, but they cool better, imo.

Or we just do it for you next week :)

I watch mine pretty regular. I don't have much traffic driving, but when I beat the hell out of it, it never gets over 190. Luckily, and oddly enough that you make this post... Brown Santa stopped by today while I was at work.

let us know how temps get after install....i really need to get a better cooler,hayden is just a cheap oreilly brand

Mine has only seen 190 once and it was pulling 7000lbs up a. Long steep grade . Cruising im 140 on average ....dunno why the 6.2 makes difference or not
Thus is still all stock coolers

fyi was just cruisin a while ago cruising at 153..then i hit the tow haul button since its the only way i can keep my truck in low gear it hit 187 :(

Installed and drove around about 10 miles of cruising at 50 mph or so. Temps never got over 142. Seemed to stick at around 138. I wish I would have done AN lines and compression fittings, but I'm going to be out of town working next week and wanted to get this thing on. I may go back and do it that way later. I took out the stock cooler and simply replaced it with the 40k.

And yes, I know it's ugly/dirty. I drive 200 miles of gravel and dirt roads a week. If I clean it now, it'll be like this again in a week.

damm badass

Just a little update after driving. Yesterday it was 102 here and driving 20 miles to town at 75 mph, then around town for 10-15 minutes, it never saw over 155*. Cruising at 75 the temps were at 142*.

Last night, coming home at 1:30 am, it was around 84* outside and the trans sat at 127* all the way home. I'm impressed and very happy with the functionality.

140degs? Lol. Something must be wrong with your gauge because there isn't one truck I've been in that cruises at 140degs from the factory.
Even my stock caddy cruising for 2hrs going to Laredo run a solid 187degs with cruise control on.

The trans fluid flows thru the stock radiator trans cooler and that water is 200degs. No way it's coming out and back into the trans at 140degs.
Even if u have a 160stat.

U must have the only truck that runs 140degs trans temp from the factory.

This was after the 40k Allen. Not stock cooler. I was seeing 175-185 with the factory cooler. I'll put my HPT on it and scan some logs if you'd like.

We're good. Although in George's defense, he does live in an area of the country that sees much cooler temperatures than we do year round. I wouldn't doubt that his truck has seen lower temps than us southern folks on average.

Come to pa ill let you drive my crewcab. It stays cool. Like siad I've never seen hot temps.I keep the display reading trans temp and always have an eye on it. I have no reason to give false info. It stays cool

That was cruising on highway after about 40 minutes

http://i948.photobucket.com/albums/a...-04-47_121.jpg

Nice temps.

at 78F at night cruising is a ok temp.

But towing and holding those temps, you must have a 15821239 or better, Stock wise.

I need to take down my temps in 89F all round ambient temps

Towing is 175-190 usually. Highest I get is going up steep hills. Cruising highways its cool.

On a 100* day it still doesn't get hot

Ya, i started mine up today and it was only 132degs but the ipc was showing 103deg outside :)

good to see it's not running hot.

Allen that was at a redlight after a 40 minute drive

i just hit 195 made 2 --130 mph runs

I think the highest temp I've seen yet is 154. This was after a 120+ run after driving in town... 109 degrees. I even called Travis to brag.
