1993 Ford Aerostar starts fine, idles fine. Put it into gear, and it stalls out. When engine is cold, it will run in gear for about 45 seconds. Installed new MAF, new fuel filter, filled transmission fluid, checked for leakes in vacuum hoses. Could it be anything other than a torque converter?
Its possible it could be other things causing the problem, but seeing as you've checked most of the likely causes, it is most likely your Torque-Converter. The lockup clutch in your Stator-Fan located inside the Torque-Converter could be siezed, causing the car to stall.
Engine stalls or RPM
fluctuates at idle up and down or dies near idle.
This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve but always run a OBD2 fault code as well as the cleaning procedure. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

tryed everthing from both cat. converter to tune up still same prblem bogs when put in gear idles fine
its an automatic transmission with 4.0 engine had a check engine light on and replaced the egr sensor which solved the engine light but then the stalling when putting in park started runs fine other wise
wondering if where it sat all winter if the fuel filter should be replaced or fuel pump has gone it idle nice just as you put it in gear to go it wants to stall and has seems like it is starving for gas
