On the ht 740 you will need to take the torque converter apart. This one is not like the smaller 643 etc and autos where the converter just slips off. The 740 you must take off all the small bolts around the converter close to the ring gear. The ring gear/flywheel is very heavy. Be very careful. After you get the flywheel off you will need to take out the stator. It is pulled by the shaft by hand and removed. Then there is a snapring to remove then the rest of the converter can be removed. Then the seal can now be replaced. The biggest thing is removing the torque converter and that it is very very heavy. This is not a difficult job but You will need help eigther a portable engine hoist, pallet jack or a few people to lift the parts back onto the transmission. Ray
