My TorqueFlite has steel planetary gear sets .. about it will not have problems ..
a multi spring conversion kit to replace the coiled spring in front clutch is necessary ??

the multi spring kit keeps the front clutch pac dish from dragging at high rpm....the big coil spring becomes unwound .....

I have 5 904s...they all have the spring kit....dont have problems with front clutch pacs...
