You definitly need the early smooth race direct drum and the 34 element dogbone sprag [not the roller clutch found in later 400's]...........You may also be experiancing a lube problem that is helping the roller clutch fail earlier than it normally would......If you are doing your own trans pay carefull attention to the lube feeds to the sprag from the center support........ATI makes a modified center support with a support bearing between the ring lands to support the weight of the direct drum. ......If you are experianced in building 400's they also sell the smooth race seperately, so you can install it on your existing direct drum. ......You should be able to run a 400 for several seasons before it needs to be freshend. .....I have several customers who reguarly put 3 to 400 runs on them before freshining .........If tou have any questions you can PM me .....Tom
