I got a 2001 7.3 and i got a tw chip with 6 tunes with the settings being stock than economy and street and extreme and tow and smoke when i put it on extreme to race a pesky fart pipe car my truck shifts hard as hell it feels like the hole tranny moves under the truck i got a factory tranny in it with nothing done to it and i put on the order form that i had a stock tranny and i was wondering if any one has this problem or if they mite have put the wrong tranny tune on it just wondering.
