Turbo 400 shifting issue

I have lost 2nd gear on a turbo 400 a few times over the years. The problem is usually a broken sprag on the direct drum. If the sprag won't hold torque and slips you won't have 2nd gear. if it locks up and won't freewheel, you will smoke the direct clutch when shifting to 3rd gear. One time a piece of gasket material broke off and blocked the hole in the bolt in the center support that feeds the intermediate clutch. This also resulted in no 2nd gear.

Mike is correct, that is also a possibility. Just be sure to check the simple stuff (governor, modulator) first before you pull the unit out.
