View attachment 1715050618 Be careful about going to the much newer 904's. They started going to lock-up converters in the late '70's. Older converters don't interchange with those. They can be recognized by a smooth, machined tip on the shaft.
Nothing really wrong with lock-up set ups. But it's not performance oriented and converter options are very limited. Good thing is that they also started going to the 2.74 low gear sets. But I don't know if all lock-ups had them or how to tell unless you disassemble it & know what to look for.
