a E40d Transmission question

The 95 F 450 Super Duty transmission gave out a month ago and had a remanufactured put in with larger oil cooler and lines with new fan clutch. My question is will putting a larger oil pan ( 3 added quarts) on transmission worth the money? Will it help keep the transmission as cool as they state in adds.
 
With a larger pan and more capacity, the oil has a little more time to cool before going through the trans again. It would also be a good idea to switch to a synthetic fluid.
 
Your money would be better spent on an auxiliary transmission cooler. Given that the unit already holds over 16 quarts of oil, 3 more quarts is not a lot of increase in capacity relatively speaking. More cooling with an auxiliary cooler should be more helpful than more oil.
 
They replaced the original transmission cooler with one twice the size of original and a new clutch on fan. The pan I am looking at has fins on it that is said to cool pan down.
 

Don't know if the extra few qrts will help but a cast aluminum pan will help stiffen up the trans case.
I had one on my 95 F-350 with 7.3 PS, although I split two cases internally, broke a forward drum, blew out a planetary, broke a torque convertor and messed up some other chit in the 5 transmissions I went thru before selling the truck, the trans and oil pan always came out in one piece.
 
We put a Mag Hytec pan & Tru-Cool cooler(45K BTU) with remote thermostatic valve on our E4OD('97 F250). Temp. runs steady at 160F & may climb to 165F on the hottest day with the heaviest load.

That said, the pan & the cooler should only be considered as insurance items that help protect the transmission. The real benefit is a properly built / tuned transmission that does not generate excessive heat through slippage in the first place.

If you have to rely on a huge cooler & oil volume to keep temps. in check there is something wrong with the transmission IMO.......

The larger cooler was put on by transmission shop that builds HP trans.. The shop said that the original oil cooler was never big enough to
begin with. This is in a 95 F 450 super Duty with 460 V8. Who handles the Mag Hytec pan?
 
I will talk to shop that put the transmission as they are a high performance shop for diesel pickups .
 
It helps. The original pan only holds about 5-6 quarts - the rest is in the torque converter and other parts of the transmission working. Increasing the "reserve" by half helps with cooling and the gives the transmission more oil to soil. The larger pans almost always have a drain plug too. If you are towing and using it hard I'd change the oil in the pan every 20K miles on a hard working pickup. Use Mercon V from Wal-Mart (Super Tech) and keep the transmission fluid somewhat fresh. Since you are only changing about a 1/3 of the oil each time you should change that 1/3 more often.


Changing the filter isn't that big of deal - since the "filter" is actually a screen. If your transmission is wearing like it should the wear particles are small enough to pass through the screen. If your transmission is throwing "chunks" that get caught in the screen its on it way out anyway. When I buy a truck I usually drop the pan and replace the filter and the fluid and put on a pan that has a drain plug. Then I never change the filter again - as long as the pan isn't leaking but continuously change the fluid.

The E4OD is far from my first choice in transmissions. The older units (first used in the early 90s Broncos) is especially notorious for getting hot as the torque converter slips instead of locking up like it should. Ford gradually improved the TC every year of production but it still wasn't that great even in 1996. The 4R100 seems to be a huge improvement over the early 1990s E4OD.
 
From what I understand the remanufactured transmission they put in is up dated to 4r100 specs. I have to take it back in several weeks for them to check that everything is tight and no leaks.I am going to see if shop can get pan like Glen talked about.From what I have read that pan holds 8 more quarts of oil over stock pan.
 
Any transmission shop worth their salt should be able to build an E4OD that will stand up to severe use. At the very least they will update it with some of the improvements found in the 4R100.

I installed an ATS converter & billet flywheel behind my 7.3L PS when I had my E4OD overhauled.

IIRC I put close to 24 liters(25 + quarts) in my E4OD with the Mag Hytec pan on the initial fill after the overhaul. I do remember a 20 liter(5 gal) pail not being enough...........That enough oil for ya? LOL

I was at transmission shop and told him about the Mag Hytec pan . He said it was a good pan put he had one that would cool it better and holds the same amount of oil. This pan has tubes passing through pan letting air pass through them. It uses a larger pickup screen.

I had this pan put on today. Manufacture says it will cool transmission 20 to 50 degrees and holds an extra 7 quarts and 10 ounce more than a stock pan. Manufacture says it will cool transmission from 20-50 degrees. It has drain plug and a plug to put in a transmission temp sensor.

If you had a trans. temp. gauge it'd be interesting to drive down the road with holes in the pan taped off / covered &amp; then again with the holes open and see what the difference actually is.....
 
Pan has a 1/8" plug on the side of pan for temp. gauge.That might be some thing to do next summer. Only have one more show
and pulls are done around here for the season. I will shortly be putting truck and trailer away for the winter. I have a
pickup truck and use it in the salt and snow in winter. WHY rust two vehicles out in this rust belt?
