Bib,
That is way too hot for
oil to get that quickly. New motors run hot, but only for as long as it takes to break in the camshaft (assuming non-roller cam) One thing to check, when you pull your tranny to replace the O-rings in the hydraulic TO bearing, carefully measure the depth that the tranny's input shaft penetrates the scattershield. It sounds possible that the inout shaft is getting pressed into the crank, causing undue thrust loads on the thrust bearing. This will get the
oil hot quickly, and destroy a motor prematurely. You can do the measurement with a straight edge, a one foot section of dowel or welding rod, and a magic marker.
of course yoyu probubly won't read this as I am most likely on your ignore list.
