Transmission oil cooler

[Carrera_man]

I have a Chevy 6.0 with six speed auto and the optional HD towing package which has an external trans cooler. Since this truck is now used for 95% towing I'm thinking of replacing this stock cooler with something bigger. Wondering what people are using that connects directly to the GM stock oil lines?

I replaced my small trans cooler in my 07 with a 6 speed. Used a B&M cooler that was 4 times the size. I did not have to cut any hoses or lines. I bought the reducers to fit the factory quick connect lines. This is an easy mod that takes more time to remove the grill than hook up the new cooler. Results- 20 to 25 degrees cooler when towing. If interested let me know and I can e-mail you the pics of the projects.

I think you need to worry about something else - like running out of brewskies.

Oh and to quote some famous people - nuf said. :B

I am glad my trans temp gauge does not have degrees on it.

Don't drink................maybe that's the problem LOL!

Your temps are fine. You can run up to 275 for short hard climbs with no damage.

I would contact Mike L at Inglewood Transmissions 714-870-7300. I bet one of their Allison coolers will fit

I would first check to make sure you need it. If your temps don't ever go above 220 I wouldn't try to "fix" it.
It's also important that the fluid gets hot enough to burn off any moisture, which is achieved above about 140 degrees.

Haven't seen anything yet in the 200's. In a few weeks I will again be in the mountains of NY then after a week off its then to western NC, SC, WVa, and Kentucky before coming home and leaving for Oregon. I'll decide after I come back from the Adirondacks and see what temps I start getting pulling steep grades when its warm out. If I don't see temps much above 200 I'll stick with the stock cooler, however if temps are going much above then I'll be putting a cooler like the one mentioned earlier.

So what kind of temps are you seeing right now?

IMHO I would leave well enough alone. I've seen people do this and break hoses or a fitting leak or something gets rubbed up and causes a leak or even cause overheating problems by stacking too many coolers in front of the radiator.

If you're not over gross on the load you should be fine.

Wouldn't stack a bunch of coolers, really would just need one good one. As stated I've seen temps in the low 190's on steep grades. Last week I came back through NW Ga in the Smokies pulling some pretty step grades in third gear and 3K RPM pulling 7500lbs, temps climbed into the upper 180's, outside temps were in the 40's. My concern is pulling grades like this in the summer and a few thousand miles from home.

I would leave it alone. Your 2500 truck should be able to handle anything you throw at it.

While I have a different transmission this transmission cooler may work. I used the factory connections that were in OEM cooler to connect the hard lines with no issues.

Now that's an oil cooler! My OE cooler looks exactly like the one in your photo. The problem would be there's a large bracket in the front for my grill. Not sure if the thickness would be thin enough to fit in between the back support and the bracket. It's something I'll need to check out. Thanks for the info!
