Need advice please!!!!

[rwlundberg]

I was just wanting people to give me their advise on what I could change. I have a 2002 Superduty x-cab Powerstroke 7.3L 4x4 on 35" tires. 3.73 gears, Auto. Add ons include:

afe air intake
edge evolution on medium setting
straight exhaust
6" lift with 35" toyo tires
Lower stall and heavy duty Torque converter
Ams tranny oil
hayden tranny cooler in front of the condenser, still goes through radiator.
Pillar Pyrometer and trans temperature gauge.

My questions are

1. How accurate is the stock transmission temp gauge? My pillar one appears hotter when the stock one is in the middle position.

2. Is having the stock temp sensor for the pillar gauge the right location for it??

3. How else, or what else should I do to keep my tranny from over heating after only about 4-5 red lights or stop signs??



I am pretty easy on my throttle when I take off and am not really hard on my truck just want to get there without ruining my tranny. I have seen the temp to 230 a couple of times and had to stop to let it cool. I am towing a triple axle toy hauler with truck and trailer weight at 20,000lbs combined. I shift down to 2nd when pulling longer grades, tranny temp increases fast while holding around 2500 rpm on the steep grades.

Please hit me with what you think could help.

Thanks
Robert

Don't beleive the factory temp gauge. They are computer controlled. That is they read what the computer wants them to read, NOT the truth. Your aftermarket gauge is a real temp gauge. Believe it.

When increasing the tire size....decreasing the gear ratio helps. That will help take the extra strain of the larger tires off of your transmission. You can do the 6.0 trans cooler. Not sure if there would be a difference between your current cooler and the 6.0. I hear one guy said it dropped his towing temp by 100*, but I have heard its a pain to install....best to have a mechanic do it. Also a deeper trans pan.

Other day I accidentally ripped the front licenese plate mount off. I think I've noticed it running a BIT cooler, because of better air flow especially on cool nights. I guess that would be a tranny-zoodad.

On my tahoe, i used to isolate the tranny fluid from the radiator, in the summertime. I rigged up a bypass hose between the tranny cooler lines at the radiator. I had valves threaded into the radiator that i could turn to either open the ports to the radiator, or close them and bypass, depending on the time of year. A quick and dirty way to do this is to unscrew the tranny cooler lines from the radiator and put each end of a single piece of trans cooler hose on each metal line to "bypass" the radiator. It made a huge difference in the trans temp, in the summer when towing. The only drawback, is that the fluid has to be heated up in the winter, or the water will not be "burned" off, and it will rust everything in the tranny. So if you try the quick and dirty way, remember to put it back into the radiator for the winter. Good luck!

* What DaveBen and bigrigr Sez (The Ford gauge is a Placebo, IMO).

2. Is having the stock temp sensor for the pillar gauge the right location for it??

** Location makes no Dif.

3. How else, or what else should I do to keep my tranny from over heating after only about 4-5 red lights or stop signs??

At 20,000 GCVW, yer at the edge of the GCVWR.. 35's with 3:73's don't help either (?).. You could add another.. or a bigger aux Trans cooler.. and mount it so it's Away (not touching) from the condensor so it (they) have Real Good.. air flow ?
