Trans said boom!!!
I pulled a 14000 lb load that was stuck. Truck pulled great but when i shifted into reverse it wouldn,t go. I gouged th gas and it went with a squeel. Shifted to drive same thing, now it wont pull a wet string out of a cats but. Whats up? Fluid isnt burnt. 2003 6.0 250,000 miles preditor!

The predator may be the root cause of the problem - especially if it is the "in line fuel module" device. The old post below explains how hard that a tuner CAN be on a tranny.

Below is from the old post:
If you want the safest tuner on the market for the 6.0 then that would be the SCT. If you go back and read many posts on this site, all of the tuners, chips etc have been tried, and the SCT is by far and away the safest and most user friendly for the 6.0.
Problem with chips that plug in line is that they do Not properly address the transmission with the increased power and they can only alter the signal input in a fixed way, mainly by changing fueling or fuel timing. With the SCT All parameters in the engine and transmission can be modified to work in concert with one another.
Any inline fuel device (ie Banks Six Gun, Edge etc) increases the Hp & Torque output of the motor, but the PCM, TCM and all of there sensors are not made aware of this and therefore cannot compensate for the problems encountered by changing the pulse width, timing and fuel pressure. Stress on the head gaskets is effected by; Boost Pressure, Backpressure, Injection Timing levels and Mean Cylinder pressure, Engine oil temp, Coolant temp, and EGT to name a few.
Mean Cylinder pressure is a derivative of the actual power that the engine is producing.
Any inline fuel device alters the fuel pulse width, fuel timing and fuel pressure, yet the PCM is not aware of this change, furthermore, the Edge (or any inline fuel device) does not monitor the other parameters in the engine, so the safe guards that are in the PCM are thrown out the window. Since the PCM is unaware of the changes made to the fuel pulse width, timing and pressure, the PCM does not know to alter boost pressure etc to maintain safe levels. In addition, the factory parameters by FMC & IH are set to de-fuel the engine if the engine coolant temp reaches 227F or the engine oil temp reaches 254F. But since the Banks Six Gun (or any inline fuel device) overrides the fueling strategy of the PCM then these safety parameters are no longer available to the PCM to maintain safe operating parameters of the motor.
Any inline fuel device it allows the factory boost parameters to go on as the factory set them in the PCM because the PCM is unaware that the fuel pulse width, timing and pressure are being changed after the PCM sends out its requests. So the boost pressure that the Edge system is allowing can become to high for the current conditions do to the changes in fuel strategy which effects Backpressure levels and Mean Cylinder pressures. The factory settings generally limit boost to 30psi, however as little as 22psi boost can break engine components when coupled with backpressure levels, fuel injection pulse width, timing & pressure or Mean Cylinder pressures that are outside safe parameters. Since the PCM is unaware that the Banks system is altering fuel pulse width, timing and pressure, the PCM does not know to properly control boost levels for the new Mean Cylinder pressures that are now being encountered. So simply put the Edge can allow unsafe boost levels to occur.
I can tell you when the 6.0 first came out the Edge was the tuner,chip of choice until people started damaging motors and transmissions with it. The edge still does not properly address the transmission.
So bottom line if you don't care about your transmission, then get an Edge or Banks or any other inline chip and go happily on your way. If you want the tuner with the proven track record then get the SCT.

From trailer life towing guide using 03 f350 6.0 auto trans 4X4 dual rear tires 4:10 rear end the max tow rate is 12,900. This is towing on the open road not pulling a large load out of the mud. So you probably doubled the towing requirement to get the load going out of the mud.

I know the pull was hard but it was one of my box trucks stuck blocking trafic and i had to do something. My tires didn't spin with no load in bed. I couldn't believe this could take out the trans. I have pulled my goosneck harder than this truck. I am just wondering if this could be a solinoid or something.

No one of my guys acually did the pulling i was directing trafic and i was standing close by. Also the trans didn't slip during the pull it just started acting funny after. Fluid smells burnt but no chunks and very little powder on magnet in pan

I've found most of my metal in the bypass auxillary filter on the right front corner of the truck. Sounds like you either had a solenoid take a dump or the big C ring in the case blew out internally. 250K miles on a 5R110 is pretty dang good. How often have you serviced the filters and fluid? I only got 75K miles outta mine running the Predator before the solenoids and clutches gave up.

temp gauge bad
my trans is going into default, first the temp gauge starts to fail then it goes into default and the gauge sits on zero, any ideas? it seems to be worse after warm up. it starts working after a long period of cool down, i was wondering about a plugged aux filter or something, or does the gauge fail while in default? tow haul starts flashing, oil is good there weren't any incidences leading up to this.any ideas?
