Tranny trouble =(

[Bacfire]

Okay, not sure of the section i should be posting this, but as i use the new Intune, ill put it there, mod, feel free to move it where it belong.

So here is the trouble, i did a couple of drag race with my car (2006 300c Awd) and ran into tranny trouble, i am wondering, could i have fucked up with a canned tune and "burned" my tranny? Right now it feel like it have no power, i can still drive the car but eng temp in the Evic go up really fast when i go uphill, and i almost dont press the gas pedal. If i am lucky i am just in Limpin mode and nothing is Fubar, but i fear for my little Nag1.

[Little update: I removed everything "tuning" that i could from the car, when im in d and floor it, it rev to 6000 and dont shift, Oem tune would usually shift at 5500, if this can be of any help.]

My setup was, Canned 91 oct cai, 6000rpm shift, increased shift firmess, mds off, trac control off, 190mph speed limiter, throttle booster at 20%, no mod to the autostick...i think i covered it all, have i done something i shouldnt, like the higher rev limit or anything, has this happened to any of you before?

Throw me some idea, i called my mechanic and he said that it could only be a Shift solenoid, that would be not too bad, but i have a bad feeling regarding this, anyway, give me some thought.

Thanks in advance for any help!

Was it running fine with the tune? I know when my Charger hits limp mode the engine RPMs will go up but the car won't pull at all. But soon as you turn off the car and turn it back on it is fine.

Do you see a CEL? What about when you run the inTune's engine diagnostics? Any codes come up?

Reinstall the tune with the Traction Control ON. Its not designed to be turned off for street use. Its for the dyno only where you don't want it to shift.

It was indeed running fine with the tune, but shuting the car down and restarting it did nothing, no code at all, trans temp too high maybe? Ill try and retune it all like i had, but with track control on....wierd, i though that it could be a good thing to remove all those crap for drag racing...Ill try it asap and come back to ya guys! Thanks so far, keep throwing ideas around!

Thanks!

May be a stupid question, but how is the tranny fluid level? I know its not easy to check and typically needs to be checked at a dealer but you need to make sure its not low. If its low, it could cause the temp to go up quick and things to operate weird. Just a thought.

I have checked it this week and it was fine, but ill be checking it tomorrow morning also when going to see my mechanic, ill get it changed also, it does not cost enough to neclect doing it even if there is only 25 000 on it. I think i might just be in limp in mode actually, but i am waiting to use the scanner to see if i am in limpin mode, and i also want to know what is the cause, it started with the inTune i used, i do not blame the product, truth is i drive like a madmen often, ill have a good idea of the problem tomorrow morning, ill be sure to post my result in here, in case some other poor fella run into the same trouble as i am right now!

Update!, cleared code on the car.

U0100: Lost Communication With Ecm/PCM
U0164: Manufacturer Specific DTC.
U110B: Lost Engine Coolant Message
P0731:Gear Ration Error in 1st <---- This fella here is probably the trouble, might have been caused by an autostick fail on my part.

Once cleared i reprogrammed everything as before the DTC and everything work flawlessly so far. Ill keep this up to date, in case someone run into the same trouble as me.
