possible solution to no transtuning 04 545rfe??
By now we know that there will not be any direct support for the older 545rfes. BUT Super Chips Flashpaq Will tune the trans. Even better that same tuner will allow you to tune the with HPtuner and load them directly onto the hand held to load them into the vehicle. in order to do this you HAVE to READ the stock tune file from your vehicle and open it on HP then build your tunes before loading them back on truck. Soooo my question is this: If that super chip can read and program the 04 545rfe and I read the file with it and then open it on Hp tuners will I be able to see My transmission on the HP editor? and will I be able to make the changes? Using the Hp tuner it Does not even read or show that the trans is there. anyone with direct experience in this or Hp tuners staff THAT KNOWS FOR SURE. please any info will help. as it sits the HPtuner is nearly useless on the 04 ram it would be awesome if it can work
