Derale 4L60E trans pan

[04silveradomykk]

Hey guys,

I'm posting this here because the 700r4/4L60E transmissions in the S series is the same thats in the fullsize.

If you're running a stall converter like me, you too need as much help to keep trans temps down as I. I've learned the hard way why my Dacco converter is called a Bake-O in the industry.

I've recently added a Tru-Cool 10,000GVW "stacked plate" type of aux trans cooler that's mounted on the front of my truck.

And it's helped a ton, but under acceleration or climbing a hill the heat created by the converter can still overcome the aux cooler.

To further aid in transmission life, I ordered a Derale 4l60e trans pan. Ordered from Summit, however I had them pricematch to transmissioncoolers.us for a total of $69.00 + $9.75 (not including filter and ATF)

Not only does it have those obvious air cooled tubes running through the pan. It also increases the ATF capacity by 2qts.

Good thing I had a new Y-pipe made to give me some more clearance to fit this deep pan.

My previous Y-pipe after the engine swap was way to close to the trans pan to fit a deeper one.

I probably wont be able to get the truck in the air and pan installed until after X-mass, so stay tuned!

Cheers ~Mykk

I've allways been curious of how those things work. I just have one of the Old TCI Deep Sump Finned Aluminum pans. It's served me well over the years, I was gonna get the Derale but chickened out and bought the TCI instead.

we'll see just how well they work indeed.

The piece of metal we see in each tube is supposed to spin the air passing through the tube to allow maximum air to metal surface/ heat dissipation

It's like the intake Tornado in my transmission, good for 50+ HP!!! J/K

Looks nice. I'm kinda curious too on how well it'll work.

[04silveradomykk]

One would think deep heat sink type fins would provide the same outcome... But I've got the pan now and we'll see

Hope it works out. I also found that utilizing the stock (in-radiator) cooler along with the external one didnt help out either. Because of the constant heat exchange between motor and coolant to the tranny fluid and the fact that late model engines generally run a higher operating temp, there was no isolation. So the engine temp rose rapidly and stayed upwards od 200* which would cause the tranny fluid to be high. Conversely it is good for the tranny temp to get up to operating temps quickly for fluid performance (especially in cold areas of the world), but where I live that wasnt a concern.
I chose to have the engine use the radiator and the tranny had its own stand-alone cooler.

Mikz, I hear what your saying. Stock my truck stayed consistent on the 210F coolant temp mark (granted GM coolant temp gauges lie and won't read above 210* until the engine hits 260*)

But currently I am running a 160 stat and the aux cooler is on the return side back to the trans. I hope I would be effectively cooling the trans fluid marginally better than a factory set-up

[hero dave]

what would happen if it gets dinged with a rock? or mud gets in it? does it has some type of anodized coating to stop corrosion? I am also considering it for mine. but I have a of rocks on the road.

In the summer months when its warmest out, how long does it take to reach op-temp? And what does it run at in traffic and on the hwy?
Also in cold months is there alot of change?

I'de run that on my 4x4 but it seems it would get plugged with debris

While @ my folks place I decided to get the trans pan out of the way. I might as well, I had a couple hours to kill before Chrstmass dinner and all of my tools are here.

I made it this far before realizing I needed to undo the header collector bolts and move the Y-pipe out of the way.

The new Y-pipe clears the deep pan perfectly. Unfortunately is doesn't clear it enough to R&R the pan for filter changes and will need to get unbolted from here on out.

So far it is holding 7 qts of ATF without issue, however a narly storm just rolled in and I haven't taken it on a test drive.

Looks good. Is the tranny cross member blocking the flow of air through the tubes?

I run the TCI on both of my trucks. Looks good Mykk! I love having a drain plug as a bonus!:D

And good idea wrapping the Exhaust.

Actually, yes. It is... oh well

[bbodycaprice]

Looks cool hope it works out for ya.

[bespurcell]

Build an air scoop to direct air through them.:D

[hero dave]

it doesn't take much air to remove heat from a metal surface....your probably cooling just as much if it wasn't blocked....

I was thinking the same thing, the tubes would help dissipate the heat.
