Yes it is. http://www.dfuser.com/Install%20Guid...structions.pdf

I believe it is 1/4in NTP

Who cares about the effectiveness of the cooler? You can't tell how effective it is unless you have the "before" to compare. You are more interested in how the trans is on the whole. I had burnt fluid and the temp never reached over 200.

 

Thanks I think tomorow night I will relocate the sending unit.

 

I just looked at my B&M sending unit and it is 1/8" NPT fitting, I guess I will have to get an adapter peice. The instructions you posted says that the ford location on the tranny is 1/4" NPT.

 

Well I got it to work, it went right into the hole. It goes in a little further than the stock plug that came out. I got some transmission type rubber line and reconnected the return line that I had to spice into. thanks

 

Make sure that the sender doesn't bottom out against a part of the trans. I'd stick a screw in so I know how deep the hole is then make sure that the sender doesn't go that deep. You do want the fluid temp not the trans temp although that is a trans temp gauge.

 

The test port in in the case, just above the pan, on the driver's side, towards the front. There is a black hex head pipe plug in the port. The port, and your sending unit, are 1/8" pipe thread. I don't think the pan drain plug is that thread.

 

So what B&M is saying, is that the purpose of a "transmission temperature gauge" is to prove the effectiveness of an installed cooler.

That is really odd.

I've always thought that the purpose of a TRANSMISSION temperature gauge was to keep an eye on the transmission temperature, so if there is a problem you can back off the load - or shut it down - and let it cool back to acceptable levels.

 

alright fellas,
i was coming back from laughlin last weekend, 70mph about 105 ambient, and i was running a constant 205*.
around town, (and anything shorter than a 1 hour trip) it wont see above 150*.
on a long run (unloaded) goes to 205*. also goes to 205* when towing (about a 6k load).
i have just the cooler that is in the radiator.
i obvioulsy am going to get another cooler, but is there somewhere else that i should be looking also? and why stop at 205? unloaded or pulling a load?
thanks

 

What kind of truck do you have? I can't think of one (maybe Ranger) that doesn't have an air to oil cooler out front.

 

your right i checked again and there is an external oil cooler.

still doesnt explain the temps.

should i ditch the stock one and get a bigger one or add another one to the stock one?

 

Okay. Yes, cooler is better, but 205 degrees under those conditions isn't critical - it really isn't. However, two things to think about -

1) if you are towing and it gets a much higher than 205, I'd be concerned.

2) it seems suspicous that your temp gauge reads the same when you go on a long (unloaded) run as when you tow 6k. Maybe your temp gauge isn't right.

I'd expect a nice long run at speed to keep the temps pretty low. In the recent blazing weather we've had in SoCal, I drove my truck to San Diego. The air temp that day was cooler than the days before, it was about 110 (instead of 116 ). In town, my trans temp went up to 195, but didn't go any higher (lots of stop and go, slip and slide with a light load - two people and a few hundred pounds of stuff).

When I got on the freeway at nice steady speed with the torque converter locked, the temp dropped to 170 to 175 - which I thought was pretty good cooling, considering it was only about 60 degrees above the outside air temp.

Oh, I have a Tru-cool cooler sitting in a box behind my desk and nice Schaeffer synth trans fluid on the way (time for a tranny service). I'm only going to put the Tru-cool on because I'll be hauling some stuff (including a Bobcat on a trailer) in gawdawful hot temperatures - or I wouldn't bother with it.

 

well i drove to hesperia today (about a 50mile trip from fontana) and it stayed about 160/180. but this was less than an hour trip.

do these things have some sort of thermostat for the trans. its like on mine, (atleast on the long trips) it steadly climbs to 205 and then just stops there.
same w/ towing.

not that it makes a difference but i do have a mag hitech tranny pan, that adds about 8 qts of fluid.

and my guage is a new (well almost 1 year) autometer w/ the sender in the test port of the trans.

 

Once again, WHAT TRUCK DO YOU HAVE?

Some have thermostats in the trans, some don't. Some need bigger coolers, some don't.

 

its a 2002 f-250 cc lb 4x4 7.3L
its got intake/exhaust, 6pos chip, ft valvebody

 

There is no thermostat in that trans. There is a pressure bypass, but it shouldn't bypass the coolers unless the trans is well under 0°F.

You could use more cooling. I think the best choice is a cooler from a 6.0L truck. They are HUGE, and will mount to the same brackets that hold your current cooler.
