I have a TCS controller and wondering if anyone uses this controller? I think I ahve something set wrong or pressure to high because my temps are high at times and in the AZ heat it can get to 200 pretty quick. I probbably need a trans pressure guage to set the tranny limits too.

High preasures on the clutch's mean they wont slip and cause heat. Atleast thats what I always thought. Maybe there is a limit? Sounds like you could use an Atomic Cooler from Derale.

 

[bigrpowr]

maybe your converter is locking up properly. is this heat coming in stop and go traffic or highway driving?

 

[Trapper]

Stop and go traffic heats the tranny up, When I got my tranny controller I didn't have a pressure guage to set the initial settings. I have two coolers, and when I did have the 7.3 with the stock computer and chip it didn't get this hot even in AZ.

The highest I've seen my temps go so far is about 185. Most of the time they are between 145-165. I've got the pressures set pretty high on my PCS and no temp problems. What speed are you locking up your tc?

 

[bigrpowr]

trapper- i meant to say "improperly" do you have a lockup switch?

 

[Trapper]

No lock up switch right now. and my TC locks up at 40mph

 

[bigrpowr]

prolly restriction in the lines... have you had it flushed with a machine?

 

[Transman]

High line will definitly cause heat, plus cause damage to the pump!
Are you using the stock rad and does it have cooler lines running through it?
Are still running the bypass tube the side of trans.The bypass cannot
hold the presure of two coolers inline.

Glad to be apart of the new Powerstrokenation.

[Trapper]

So should I run the cooler in the rad or the aftermarket one?

 

[Transman]

You should always run the fluid though the cooler.This will bring the trans fluid
to engine temp first.Then though the aux cooler. The stock 7.3 cooler brings
the temp down 10-20 while the installion of the 6.0 will bring it down 30-40
degrees.

When you say tcs controller do you mean compu-shft?

Glad to have you here sir! :rockwoot:

NO not a Compu-shft the TCS trans controller has way more adjust ability.

Start with the basics. Hot at idle/stop lights indicates low cooler flow or lack of air flow thru the cooler. Look for air flow blockage, bugs, bent fins etc. Engine fan ok? Is eng clutch engaged and pulling air at warm idle? Try pulling the rear cooler line and measure flow for 30 seconds into a container. Go from there. If 1 of the 2 coolers is the original, might be half clogged reducing flow.
More pressure everywhere from electronics...Just dumps it back to pan, steals it from where it was needed, pump works harder, and apply pressure maybe actually lowered when needed most. :shrug:

I agree with your routing, but the radiator cooler doesn't control ATF temps to engine temps. The radiator cooler is in the side of the radiator that has the cooled water in it. That water is anywhere from 15-100 degrees cooler than the engine's temp. If it were the same as engine temp, why have a radiator at all? If the temp is the same the radiator isn't cooling anything.

 

[bigblockhorse]

Mark is correct, for the ones who say otherwise get your trusty temp gun and do some testing.......................

 

[Trapper]

I will get around to it soon. Its alot cooler here in Texas and I don't half to drive as far to work and very little traffic.

60º ambient (fluid temp)

cold side of radiator (what would this be, 150º at least, right?)

Looks like it warms up the fluid to me. Up to a certain point...

Of course when trans temps exceed 150º (assuming the cold side of the rad stays the same) it would then serve to cool the fluid.

What am I missing here?

You guys have it so set that the radiator cools the fluid, not warms it, when it's obvious to me that it does both. :shrug:

 

[bigblockhorse]

The radiator will have no heat into it before the t stat opens, the damn atf will have heat in it from the converter shearing the fluid long before the stat opens. This said how in the hell can a cold cooler in the bottom of a radiator add heat?

Gotta remember the vast majority of you guys have your probes in the pressure port on the trans, the fluid temp coming out of the converter on its way to the cooler is way hotter.

Just because someone who ought to know better says it aint so dont make it true, I think Mark might know wtf he's talking about.


Rekon you could pull over and wrap the tranny in ice, wait a bit then take off again then yeah it will ADD some heat, for a short bit.......................

You will never have 60° converter out temp and 150° lower tank coolant temps. What you are missing is the facts and the understanding of how these things work. There is really no reason to even argue about this. It's real simple to test it. Put a temp sender in the radiator and another one in the cooler line.
