Are they worth running on the truck for towing to help cool down the tranny or not ?. I've debated on buying g one and yes I should of when the tranny was built. Your thought's on this is definitely needed !!<img. (((( picture added)))

honest question.

I hate them , weight like 40# and cost you an extra 5 or so quarts every time you go in. Lil prone to leak , but DO have a temp sensor bung and drain bolt .

I had a Furd automatic trans engineer tell me " You will just have more Hot fluid " . Dunno if im buying that , but just do not know.
Some say / have proof they lower fluid temps , some.

Interesting topic. Thank you

Yes they are absolutely. I've seen the results with my own truck. Back when my 48re was stock just running empty in traffic during summer my temp would hover around 190-205. After I added a cheap b&m pan with 6 more quarts it dropped temps to 145-165 max. Its not just additional fluid which of course helps but the aluminum design with cooling fins. Sure they weigh more but also wont crumple up from a small ding either. Now on my firepunk I have a ppe pan and my temps stay at 145. I think I paid a buck fifty for the b&m and it was worth every penny.

I went ahead and put down on a Magtech deep pan and will soon put it on the truck. Hope it does some good that way I can honestly say to the WIFE it was worth the money !

Running a Mag-Hytec DD pan here, big fan. The extra capacity is nice, and I am pulling temps out of my Cooler line return, been fun to watch the differences.

Does that pan have O ring or gasket ?

Whatever it has make damn sure to proper torque it via torque wrench . Aka the directions or Oem value .
My son did not , don't ask ....

Mag Hytec Dodge-727-DD installed , 5-2013.
Cons :
Expensive
drain plug sticks
OEM gasket in this application
heavy to me, gettin old.

Pros:
Magnet drain
More fluid(extended drain with proper oil analysis), IMO, also gives chance for more debris to drop to bottom of pan,
A356-T6 aerospace quality aluminum structural and heat dissipating materiel/design
Great finish still looks like new.
I lost 10-20 degrees heavy load
temperature probe port to double check POS sensor

Definitely want to use good calibrated in/lb torque wrench on any mystery metal 48re.
Torque Specifications:
鈥 Lowering Block Screws: 35 in lbs
鈥 Filter Screws: 35 in lbs
鈥 Pan Bolts: 120 in/lbs 144 in/lbs max!!! (not 144 in/lbs-192 in lbs/like directions say)
For drain plug, Apply a thin layer of oil to the drain plug O-ring and install.
Tighten drain with two fingers using the short side of allen wrench, DO NOT OVER TIGHTEN.
I just tightened till I thought tight, first oil change almost snapped allen wrench so after that went a little looser , should have spec!!!

Derale put cooler tubes in a deep pan like Integrity Trans did in the 60s and their pans are cheaper. I'm waiting for them to make one for the 68rfe. Craig

I'm not too sure where the smarty pulls the trans temp from? But just to clarify my post that is where my temp readings come from. But either way I'm sure you will be happy with the mag pan. I know I used to get really nervous in traffic watching my temp. Now I never worry.

I installed a B&M pan, made absolutely no difference in temp. Upgraded the tranny cooler, made a big difference!

Your money is better spent on a remote trans cooler like a derale. People claiming 50* temp drops by adding a pan are high...

The Goerend pan has a real 1" drainplug and a port for the sensor. Much better than my old Mag-Hytec I had on the 24v.

Nice! I would have purchased this one if it was around. I've been running my Mag for 8 years with zero issues. I have a built tranny and the builder likes the deeper pans. It does not hurt to have one, but not too sure if it really matters either.

And like stated before, do not over tighten the drain bolt. It will get stuck! Ask me how I know. My fill plug in my Mag-Hytec rear end cover I used to have got stuck. Thank God for the Harbor Freight tiny funnel. Has to fill it thru a port. Ha. Lessons: Remove filler plug first. And do not over tighten plugs.

The true reading is between the pan and the torque converter.
