727 Rebuild Blues

Thanks Kimmer!

Its a lot of work changing out drums if they don't work!
I've been converting my transmissions to wide band 71'onwards DRUMs due to ring seal failures (and worse).
I've also been using the same input shafts but noticed an extra oil-hole in the pre 71 shafts?
Will this have any effect inside the LATER STATOR?
I haven’t noticed a problem, but I have changed the input assambly with the front drum and pump. Kim
