trans temps cooling

[03dmaxkolb]

iv read on here and iv heard anything up to 230 is ok. but i hate seeing mine run 200ish all the time. it was 80degrees here yesterday and i was in town it was 220. after a few launches last night it was 230! iv heard the deep pan is a waste of money but im thinking bout gettin one. i have a precision TC and its stalled at 2300 instead of 2000 i wander if thats all my problem for this heat? any thoughts?

You can tune your trans to lockup the TC real early (low mph etc.)... may help temp during city driving. Sounds like you really just need a cooler though... everyone that has the Mike L. Cooler seems happy! may want to check on that. A deeper pan isn't a bad idea in general, though it will just delay the hot temps...

Don't do it!!! It was a complete waste of money for me. Just makes changing the tranny oil more expensive (not including the cost of the pan).

Get a MikeL cooler. I can tell you that those work for sure.:woott::woott:

Here's a thread to make your own cooler.

ya i have considered the cooler. my tranny when first built got a lil messed up sent sum metal threw the system i think a cooler would b in my interest anyway lol. im jus going off some buddys of mine got lower temps only thing diff is the pan. but my cooler could b a lil screwed

Another option which is a direct drop in replacement is MikeL tranny cooler. See Link below. I have Mikes cooler installed. Temps of tranny are below 200 even when towing in 100 + temps.

There's always a difference in opinions but I don't believe a deep pan specifically a Cast Alum being a waste of money. Will it cure over heating ? No Will it lower temperatures? Yes

It's a combination of items that get lower temps. A Cast Alum pan is a good heat sink or source to shed temps quicker then a standard steel pan and in additional the extra capacity gives you more fluid for longevity of break down in additives and longer drain intervals. With a deep pan and a bigger cooler you will achieve lower temps.

Forget the in dash guage the proof is in the sump temps. With a cooler and pan you will see a 20+ drop in fluid temps.

I never saw the drop in temps with the deep pan. I ran the deep pan for a month prior to installing the MikeL cooler. At the time I was running an ATS trans that REALLY made heat. What I did notice was the temps came up slower because I had more oil volume. More oil means more mass in the system, which takes longer to get up to temp. What I was seeing was temps as high as 240* when idling or driving in stop and go traffic. I was cooking my trans.

The issue was the engine temp was low because of ambient air temps 50*-60* and the fan clutch would not engage, thus the stock cooler had no airflow. When I added the larger oil cooler, I stopped having the problem.

What I am doing now is removing the deep pan. At this point, all I get for having the deep pan is more money to fill the thing with oil.

Results may vary.....

I will admit that I never ran just a deep pan (cast alum) and monitored fluid temp. I'm also running a ATS transmission. Nonetheless a deep pan alone wont solve excessive heat issue unless your parked for a period of time and it will shed heat fast.

A bigger cooler is the way to go.

Also unless your running a sump temp guage the OEM guage in the dash doesn't represent the actual fluid temperature. Once the truck is up to normal operating temperature with all the heat soak my factory transmission guage would mock the engine temperature unless the transmission was being semi abused then it would rise above the engine temperature. My sump temp would always be a min 20 degrees less.

Most of the time a lot more then 20 degrees! Unless the ambient temps (summer) are high my sump rarely rises above 150 degrees while my engine temp hovers in the 185-195 range. Summer it will rise up to 180 degrees. Very far and between will I see anything warmer than that.

With all that I do agree with you that a deep pan will not solve (alone) high transmission temperatures. Waste of money? Yore mileage will vary! :hug:

If you have a sump guage as I do record your current temps before and after the change and lets us know what you find out. Just be honest

Chances are you don't have one. One thing for sure having one definitely shows you the efficiency of the cooler and the worthlessness of the factory guage for actual sump temps!

Trans temp sensor is mounted on the pressure switch manifold and therfore records heat sink temps on the valve body. Fluid temps will be lower than what the factory gauge shows you. It is still an accurate reference.
