I didn't realize it would be a bad thing to add additional cooling to the stock cooler. If both coolers have 3/8" fittings, how is it more restriction than one bigger cooler with the same size fittings & similar sq. inches?

from what I understand it is not the fitting size but the tube size. I had Told Brian that I wanted them 'inline'..... he looked at me with his head cocked toward me and said, "nope, the 7.3 is coming out as it will cause a reduction in the flow". I had just spent above 4Gs on this guys transmission and if he said that it will be a handycap to the 6.0.... I believed him. (He covers the warrenty on his tranny, so...it breaks, he fixes....thats enough for me)

I want to say also that 'adding' the smaller coolers that you are looking at will 'help' the cooling of the transmission (as I thought the inline would do), but by buying just the 6.0, that is All that you need and the 7.3 will 'pull' the full potintial of the 6.0 down a little. By having just the 6.0 it will aliminate the need for any 'add-on'. this is the drift that I got from Brian.

Interesting. I'm no expert, usually your smallest point limits what flow is. As long as the tubing wasn't undersized compared to the fitting on a tube/fin cooler, I wouldn't see it as being a flow restriction.

I checked car part this morning before heading to work. Only the one posted above showed up. I'm at work now, checked again...wow...anything from $20~300 all over the country. I'm leaning towards just doing the 6.0 cooler and calling it good.

Hmmm, Les, I put the TruCool inline with the 7.3 cooler. Do ya think I should just route it through the trucooler and pull the 7.3 out? I'm the kind of guy that thinks more is better!! Good discussion though.

Les is right, Brian told me the stock cooler would be too much of a restriction along with the tru cool. He's also not a big fan of inline trans filers for the same reason.

FWIW, I have a V-10 cooler in my truck (about the same size as a tru cool IIRC). I was seeing around 150-160* temps and thought "hey, why not add my stock cooler back into the loop, more is better right"?

WRONG!!! now that my coolers are hooked up inline, my temps will climb to 180-185* when driving around town, once I get on the freeway and get the air moving again, they do drop to 155*. Needless to say, the stocker is coming out this weekend, can't risk that kind of behavior when we head out with the 5er neext week.

Ya you would think more is better, unless there is a choke point and limiting flow.

rufushusky- How long did it take to hear back from your vendor from CP? I've sent to two different vendors and haven't heard anything yet.

What do you guys think about this bypass kit? It uses 3/8 NPT's and 3/8" Barb fittings.

Derale Cooling Products 13011 - Derale Performance Fluid Control Thermostats - Overview - SummitRacing.com


I was thinking it could be useful when its winter and below 0*. This would keep the fluid from going through the cooler allowing it to warm up quicker. The thermostat would allow it to go through the cooler when it opens. Sometimes it takes 6-8 miles before the trans will even lock the TC. Installing a 6.0L cooler might make that wait even longer...

What do you want????
Do you want your transmission 'cooled' or 'heated up'?

The 'kit' said that it would open at 180 degrees.....

My transmission is set up (as most BTSs are) to run about 70-80 degrees above the outside temp.....

Hence outside temp (example).....30 degrees + 80 degrees... = 110 degrees.... (outside temp)90 +80 = 170 degrees

When this 'valve' opens at the hight setting of 180 degrees with the 6.0 trans cooler, it will drive the temps down to (to the normal temp of )110/180 degrees and the valve will shut and the trans temp will climb again....

Does this sound like something you should to?

I have the number of a good transmission builder for when you need one. (His transmissions are guarrentied for life, but if you insist on putting on this valve, for you he may make an exception)


Just my thoughts, it is your truck.

I understand where your coming from, but I don't think you realize the temp. swings we have here in Utah vs where you live. During the winter its not uncommon to hit -20* and during summer 100*+.

With your #'s an ideal trans. would have 180* during the hottest months and only 60* during the winter. But then again I don't have a $4500 tranny. Ever see the Nissan Titan commercial? Its got a heater & cooler to keep it at operating temp. When I looked at the bypass kit, I wasn't as concerned about the opening temp as ports size initally. Ever hear of the Ranger heater core mod? Ideally if the open temp was correct I might could have my cake and eat it too!

I have actually kicked the idea of a bypass valve round since the 6.0 coolers capacity is soo much more than stock. I decided against it for the simple fact it doesn't get cold enough in mass and I going to run a winter front which should help. In Utah were is obv gets much colder it might not be a horrible idea.

Since I am not a transmission tech, and I am passing on what I have been told second hand from a transimission tech and the rest is my opinion.

There is a transmission tech (Mark) that fellowships here. It may be good to send him and e-mail and ask his professional advise.

Well, yes, it is! I want my trans to operate around 170-180°F. That's the temperature the trans was designed to operate at. It can run there forever with no heat damage. Cooler that that causes excess drag and burns more fuel. I like better fuel economy.

And for the record I was never a transmission tech. Transmission techs build transmissions. I don't do that.

And for the record Mark, it was never my intentional to do anything else but to give you the utmost respect. Sorry for the mislable.

Thank you for you answer.
