Well took my 2010 Ecoboost Flex to the shop they said the torque converter is not locking up so where's the best place to buy a complete rebuilt transmission gotta 170k miles on mine right now so instead of just changing the converter I'd rather change the whole transmission. 2010 3.5L EcoBoost 6F55 AWD; AA5P-7000-DA,DB AA5Z-7000-DRM is what i was told i needed Any help would be appreciated I live in southeast Oklahoma we don't even have a trannie shop
