Can't be two busy! He's always on the dam computer!
The computer stays on all day.
sure sure thats what they all say!..lol WEll Macking nows your chance to chat with mike !:thumb:
I two have a ATS transmission and a " Mike L cooler " Driving with air flow across the cooler does make a difference with mikes cooler.

Yes. However the stock oil filter housing on most models has a bypass built in it as well. I believe it's set to 63psi? You wont see that pressure at the dash gauge though unless you have a 01-02 with the sensor right after the oil pump. That just what it opens at. Now what the journals see after this another matter. I think they call it "residual loss"?
Michael, every filter manufacturer has different settings for the bypass. In the allison the spin on is critcal because it feeds control main pressure which feeds the valve body and solenoids. 125 psi in and anything over 126 psi gets dumped to sump because the solenoids can't handle it. If pressure drops at the spi on filter on the Alli, all hell breaks loose.

So sorry Mikie. I was speaking of the engine oil filter housing. So yes, what Mike said.

What a great thread filled with differing opinions/views/thoughts to ponder. All seem to unanimously agree a cooler WILL in fact help the temps. Wether or not oil can/will help? Jury is out. That said, if ever there was a thread prompting enthusiasts to upgrade to the "finest" tranny cooler ever made, this is it. Mike L can I please get a quote on a "Mike L/Setrab cooler for my 5 speed Alli? Thanks in advance. PM is fine or you have my number on the voicemails. Please don't gouge me on the price for publicly stalking you for a price quote lmao.:rofl:
Call me in the morning and I'll take care of you extra special. Sorry I left you hanging. No excuse.:hug:

No worries. Thanks ill def give you a shout tomorrow.
I am sure my last post is already going to cause crap, but oh well.
But riddle me this, "if" the tranny is already producing too much heat and is burning the oil (apply your own technical terminology), how would a cooler help?
I am not putting down anyone's product, nor supporting any other initiative, I do agree that if a cooler can keep ahead of the heat build up it is a good thing, but if the transmission fluid is already toast (again, apply your own technical terminology) before going to a cooler, I don't believe any amount of cooling that oil is going to reverse the damage to the fluids.
So theoretically, you need to reduce the heat that is being generated in the first place, better parts, better fluid, better/correct tolerances in the parts, better parts(material), better shift patterns(better computer programming for the transmission), etc... The cooler just helps to maintain that temperature, obviously adding something cooler to something hot will make things cooler. But if it already "too hot", isn't to late?
How much fluid actually gets pumped through the cooler and dumped back into the pan in any given interval? How much of a temperature differential is there? I have no idea, and this is a serious inquiry. I'm sure the stock cooler sucks compared to almost any aftermarket cooler.
Somewhere I read about upping the pressures to move more fluid, doesn't pressurizing actually increase heat? I'm not sure how that can help? Seems to me that more fluid that is cooled would be better, but it goes back to my question about the amount of "cooler" fluid returned to the transmission.

And MikeL said that forget the fluid forget the cooler if your seeing excessive temperatures, you need to find the root cause as to why, not put a band-aid on it! BUT no matter what if your aren't seeing excessive temps any additional cooling will create longevity to the life of the fluid which will result in longevity to your transmission clutches and holding capabilities I assume.
Apparently I missed the part about the "excessive temperatures" from Mike L., and maybe this is why (missed a post/misread a comment) the forums sometimes get blown way out of proportion, what I got out of all of this was that a "good" cooler would solve all the temperature problems.
I agree that keeping it cooler all the way around is better in the long run.
Yep it was there, just hidden and I did miss it. I do agree with that particular part.
