check engine light comes on and off with knocking sound
I've got a check engine light code p0740 which has something to do with the TCC. If I accelerate hard from a stop it makes this knocking sound that i can hear and feel under my feet, and the check engine light comes on (if it wasn't already on), then if I were to make a hard stop it will knock again, and the check engine light will turn off.
Does anybody know what this means? Sounds as if something down there is lose and moving in and out of place or something but i'm not really sure.
