When driving no more than 10mph, when I let go of the accelerator to slow down a little (suppose there's a bump ahead), the car stumbles - a pretty violent shock.. Nothing like this occurs at any other speeds/situations..
I had an excessive EGR flow CEL.. I just fixed it and it turned out to have nothing with this problem (I thought it would)..
I had my ATX recently completely rebuilt and I still have warranty on it. Does this sound like a transmission problem?
