I already posted in another section but truck is an 06 Mega Cab automatic. Truck idles perfectly but when you go from neutral to drive or reverse it lunges forward or reverse and then dies. Kind of like when you stall a manual trans. DTT said they think it needs new injectors but I still think it has something to do with the converter? Maybe stuck locked up? please help!!!

Truck has superchips and bored out injecters.

 

are there any codes being set? if so what are they? try un-plugging the connector for the fan clutch

that would be the 1st thing i would check

 

i haven't purchased the truck yet so I can't really check the codes. I will post again when I get it.

 

Run away! Run away!

 

your torque converter is toast. I have seen this may times old and new trucks

 

I am getting an 06 2500 mega cab laramie with 50k miles and 6" fabtech lift for 21k. You think its a good deal?

If the converter went out would it throw metal into the tranny or would it stay self contained?

 

If the tc took a dump, you would need to get the tranny flushed properly, along with the coolers and lines. valve body should be checked. Missing any steps would probably waste your time and money.

 

That was gonna be my guess too...sounds like the TC is staying locked?

 

I had two 2500's CTD come into shop this month with same problem. Dropped pan no metal found but did flush coolers and replaced torque converter. Under warranty of course.
