i got it from vince at trifect! he said to unplug the battery did that then i pmd him again for the past like month and he wont return my pms what so ever kinda pising me off actually

 

see above.

 

theres a tsb for that u need to go to the dealership and get a reprogram. iv done a few of them.

 

What are you trying to say its not a good tune?

 

im not sure... all i no is that theres is a service bulletin for that exact problem. and it says to reprogram the pcm

 

back to stock wont that mess things up?

 

the only down side will be that u will lose ur tune once they do it im prety sure but dont hold me to it.

u would have to get it retuned if that happens. im not sure though i never reprogramed a car w/ a tune that i no of.

 

well thats what im wondering if i did that would mess up the tune and transmission settings i wouldnt want that lol or would i be better off just letting it go backwords? lmao

I dont know of any other place where this tune is at either so its a pain lol

 

well i just checked gm service infomation and i was worng that tsb doesnt apply to ur year car.

 

They are right it is most likely the tune. I had done this once on the very first tune we had done just by trying to flash a complete program instead of copy pasting parameters . The different OS and year can cause this. A simple reflash with the correct year OS and tune should fix it .
