I found this page when I was looking for a bellhousing for a t-56. It states that

"Borg Warner transmissions are now owned by Tremec Corp, however, the design remains the same between the two transmission lines. Borg Warner transmissions, for the most part, use a single rail gear selector and carbon fiber lined steel synchro rings where the Tremec transmissions have a single rail moving three shift rods internally. This three rods have spring loaded detents that make the transmission feel notchy during shifting. Instead of carbon lined steel synchro rings, the Tremec is built with solid bronze synchros with no linings. It is for these reasons that the Tremec does not like to shift well above ~6,500rpms."

I don't know if the T56's are involved in this, but I would find it quite interesting if they are. That may explain why my "tremec" (as it says on the side) may be burning up the (carbon) syncros. It also may explain why the LS1 6-speeds are prone to breaking when the LT1 M6 holds up well in most cases. Just think that this is interesting. Later,
