i recently installed a 514 stroker into a 1965 F100 along with this instalation i put a boss hog 2200-2800 stall torque converter and a TCI valve body into the C6 trans, i think this torque converter is locked up, when the trans is put in gear with the foot on the brake the engine bogs down, with foot off the brake and gas is given the truck starts moving instantly. is there anything i can check to see if it is something else besides the torque converter?, will a certain type fluid matter? i used Castrol Domestic Multivehicle Automatic Transmission Fluid i put a quart in it before installation, ive checked the vacuum hose, is there any thing i can do to make sure its the torque converter and not something else, i really dont want to pull the part, deal with warranty stuff/ or buy a new one, to end up with the same problem,
