Good info but...where in the flow of things is the factory inspection port? On its way into the tranny or on its way out to the cooler or somewhere in between?

Normally it is out of the front pump for checking line pressures. I can't remember if it is before or after the line pressure solenoid. Pressures are as follows for stock:

Park / Neutral 50-65 psi
Drive 50-65 psi
Reverse 85–110 psi

So then that would mean it is fluid that has returned from the cooler coming out of the pump ready to go into tranny and do work...correct?

True. You get a wide range of temps depending on where you put the sender. The fluid can be 20 to 50 degrees cooler entering the transmission than leaving it.

I find I am much happier not having a gauge and only worrying when the OD light blinks.

OK, After a ton of searching, this seems the best thread to post in.......

Where do you guys mount the blower trans coolers? I dont want to block the radiator and not sure it would fit there with my light setup anyway. Tried on front skid plate but bumper sits too close to body to even fit in there........anyone?

I placed mine on the driverside behind the grille up top. I had to trim the grille a bit.

Bronco has two big coolers with fans. Temp sender on a bung welded into the pan. Big buck race C6. Lots of engine, lots of hard use. NEVER an issue. 190 typical. 210 really working it (WOT uphill sand wash in summer 2wd).

Got an E4OD behind a hot rodded powerstroke that also gets worked hard. Two BIG coolers, temp sender in the pan. No fans on those coolers (oversized aftermarket intercooler in the way). Runs 190-210 when moving. But hits 230 in the 2 hour long border lines in summer with heavy trailer.

I run Swepco 20wt in both trannys.

Same place I put mine. B&M cooler, spal fan.

I guess I said it before . Anyway 2 of the biggest coolers with at least one with a blower are necessary in the sand , especially in Baja where the washes have very deep soft sand and low gearing is required to keep going.
I sure dont like the discussion of using the test port for a gauge sender. Just put the thin in the out[put line or the pan. Pan is my pref.
The proof is base on the experience of many of us.

This is using the factory pressure port correct Kris?

I will be running this for my sending unit for the trans gauge, plumbed through the out line, before the radiator and trans cooler lines. Seems that is the best/ most accurate spot.

So where on the pan are you putting the bungs? side/top rear/? (c-6) thanks,pm

It should go in a factory or tapped port on the side to protect the sender and wiring. See the right side of the pic below.







I have changed my sender to the E4OD Test Port to find much more accurate readings. I want to see the hot internal oil, not the cooled pan oil. I have noted a 30 degree increase in temperature gauge readings which gives me much better information. My gauge now averages 180 degrees, as opposed to 150 degrees, at normal operating temperature. Then again, I run a massive stacked plate tranny cooler.

reviving an old thread. That pressure port is not a good temp location. Bung in pan is best.
Trans flow simplified - TC(hottest on not fair place for temp sensor-trans out to cooler - cooler into trans-works through clutches/shafts etc- dumps in pan then back to TC.

The B&M cooler/fan combo PW uses as well as I use has a puller fan and the instruction tell you to mount in front of radiator. Does it make sense to mount a puller fan in FRONT of the radiator? When the guy wired it he wired in reverse to make it a pusher and I never really thought about it but what does everybody think? Why would they make a puller fan that mounts on front of the radiator?

Anybody else have the B&M/Spal combo? How did you wire it? pushign or pulling?

I was under the impression that pullers were more effecient. I have a puller on my cbr and its in front of my radiator. I know that the engine fan is pulling as well but air follows the past of least resistance, right? So to have a fan that is shrouded directly for your cooler seems like it would be more effecient. Just my thouhgts.

in that orientation correct...my fan is mounted first then cooler then condensor then radiator then radiator fan...fresh air is coming through grill and my fan if wired like BM says to would be pushing it back forward.

I called them and they said dont mount it in front of the radiator unless the fan can be mounted behind it, not in front of it.

I plan to find the same spal fan as a pusher.

Its not as simple as changing the polarity of the fan and turning your cooler around?

No shrouds and trans and Motor run cold all day long . eBay fans on tstats two pushers one big puller. They pull less amps and more cfm than flexalite . Just dont mount the cooler like my dumbass did too

When the pan is removed you will get a pretty good idea where to put the bung so as not to be to close to stuff inside. My E4OD choice was drivers side 2/3 from the front. Plenty of room thereabouts.
C6 guys have to answer your question
