01 dodge dakota 2wheel drive v6.
There will sporadically be a loud thumping under the hood and a lack of acceleration. Letting off the gas for a few seconds stops it, and itg might do it again right away or it might not do it again for a hundred miles. Just put in new transmission and it still does it. sounds like someone under the hood beating on it with their fist. Truck never does it when at mechanics, but as soon as I drive it home it will do it again. No engine codes. please help
