Default Found my high temperature problem

Well as some of you know I had been running kinda warm on the motor and trans here lately, and couldnt figure it out. thought maybe my thermostat was going bad, or the water pump was, so I replaced the water pump, last week, and lo and behold, it overheasts on me again today 250* by the crappy stock gauge. and my Autometer trans gauge was at 240*
well I get it to cool down, to do this I parked it , and then unhooked the electric fans,from the VSC to have them run all the time while the truck is off.
well after a brief period of letting the motor cool, I got in it and began to drive it. temps are now back down to 180* and the trans is at 150*.
and get this they stay there!
Even in stop and go traffic the motor and trans never got above 190* @ 98* outside.
So with this little observation. I have come to the conclusion, along with a few others, that the VSC from Flex-crap sucks the big one. I even had the 40Amp, one and it was letting my truck over heat!
so there, I am running the fans manually now, untill I get one of those harnesses to run the fans off the PCM.

What's Flex-crap's real name so I can beware?

Ya know ... now that I think about it .. mine was running a little warm when I was dragging the boat around a while back ... a LONG while back. I was thinking that I couldn't hardly hear the fans running. I know I need to do something about it now.

Good info there Thunder.

im in the same boat here too. according to my stock gauge. i usually run around 175 on the temps with 292s and a 160 stat. sometimes i notice it works fine, and others i notice it creeps up to aorund 210. it pisses me off cuz it didnt use to do that. i also found out that with the ignition on, and i turn my ac on, the fans no longer turn on like they did awhile back. im on my second controller thus far.

250 can start warping the heads. Just pin it to blue42 on the pcm if you have edit. It works well.
