After the engine and transmission have been separated measure the depth of
the torque converter into the transmissions bell housing. Use this measurement
to insure the converter is aligned with the transmission oil pump correctly when
reinstalling. Use a straight edge and a tape measure or ruler, and always write
things down so you don’t forget.
Always perform a complete inspection of the torque converter when it is
removed. Check the drive hub for burrs and scratches. Most of these are easily
removed by polishing the hub with a piece of crocus cloth. If the hub has deep
scratches or a major groove, usually where the transmission pump seal was
riding it must be replaced.
A seized stator will cause overheating resulting in a dark blue hub. If the hub has
been overheated a frozen stator is likely the cause. Place the torque converter
on a bench and place your fingers through the hub into the splines of the stator.
This should turn freely in one direction and feel lock up in the other. If a torque
converter has a bad stator it must be replaced.
Check the studs and threaded mounts for stripping and wear. Also check the
seams for any signs of leakage and replace the converter if any leaks are
evident. Torque converters will balloon from too much pressure and must be
replaced when this happens. This is often found out after hearing a whining
sound coming from the front of the transmission.
