Hi all

I have a 2005 F150 Screw with the 5.4\3.73 rear end and tow a 6000# camper would a programmer help with the trans temp's?

PS It does have a ext trainy cooler.

Thanks
Mike

 

Hi Mike,

That's an *excellent* question.

For the first time ever, Ford really did a wonderful job in terms of the capacity of their auxiliary transmission cooler - for example, you can put on the emergency brake, drop the truck in gear, open the hood and put your hand behind the cooler - and at that low an engine speed, you can actually feel air being pulled thru that new and much more efficient tranny cooler - and that's a first.

Most importantly, the tranny fluid needs to be at 170 degrees for maximum fluid (and transmission) service life - for every 20 degrees above 170, you reduce the transmission fluid life in half - something most people do not know.

Now, to answer your question - yes, *proper* custom tuning will help to lower those temps, as you will enjoy reduce slippage - and here is also where you also need to be careful. The best way to get the most linear & progressive set of shift characteristics that will reduce slippage the most without giving a harsh shift is by having us do our custom tuning. Now don't get me wrong, almost any major name programmer on the market will reduce transmission slippage some - but it's *how* they do it that matters.

The key here is getting the longest possible service life from that transmission, while also getting a set of shift characteristics that does NOT spoil the inherent smooth character of that vehicle, yet reduces slippage as much as possible. So it takes an extremely careful calibration that combines the correct pressures, clutch fill rates, torque management, and numerous other aspects that gives you a nice smooth shift in "normal" driving (including towing), yet progressively firms up in a very linear fashion as you give it more and more throttle opening - while providing maximum reduction in slippage. And not just in the clutches & bands, but also, and perhaps most importantly in some regards, the torque converter itself. The torque converter has the most slippage, and thus in many situations contributes the most heat to the tranny fluid. So it takes a thorough knowledge of the transmission's design and operations as well as programming ability to come up with a combination of shift & TQ lock/unlock characteristics that delivers everything I've described above.

So the answer is yes, it *can* be done - and it's best done by our custom tuning. Right now is a great time to get in on that, as we are currently running a Group Buy for registered members of F-150 Online like yourself on our Troyer Performance custom tuning, loaded into the most advanced hand-held tuner on the market, the XCalibrator 2 - here is a link that will tell you about the Group Buy: https://www.f150online.com/forums/sh...d.php?t=227214

And of course, please feel free to give us a call at our number listed below to go over this in more detail, we'll be happy to help.

Congratulations on your 2005 F-150, & we hope you enjoy it for many years to come!
