904 brakes torgue converters

Welcome to FABO! Other things to look for.....engine idle too high.....bad oil pump in trans(even if it is "new").... poor quality metal in torque converter hub....mismatch of pump and converter hub (there are different size converter slots and pump lugs through the years)....and possible alignment problems that require a dial indicator to check if the bellhousing is centered to the crank. Good Luck!
