2005 awd 300c procharged
I've had limp mode creep up on me and I'm becoming very concerned about it from a safety perspective. Once it happens, I lose all ability to accelerate and basically have to be able to cruise to a spot to turn car off and then back on and then it's fine. Or I'll have to clear the codes and then its fine. But I'm concerned because there are a number of places when driving on the highway around chicago where there is absolutely no shoulder or exit and if I get stuck on one of those, I and my passengers could be in serious danger from other highway speed cars.
I am running slightly smaller tires (27" tall vs 29" standard) with compensating adjustment made for tire size in my diablo tuner. If the tires are part of the equation and hal LX just can't handle it, I'll get a new set of standard factory height tires all around (awd). I'd rather keep the little bit of gear if there is some other variable I'm not thinking of though.
The codes it threw last night were:
P0700: Transmission control
P0730: Incorrect gear ratio
I'm running a procharger so much more than stock torque/hp and that could be a contributor of course.
I haven't tried running with fuse 17 pulled to see if its a torque management issue. I suspect it is or that is part of the combined issue.
Last night it happened when I let off the gas after a very aggressive acceleration. Basically I let off at 5k and it hovered there then went into limp mode.
What do you guys think?
Thanks in advance.
