Are the Borg Warner and Tremec trannies different?????
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,
Brian

The Tremec T56 from the LS1 seems to have a lot more issues than the LT1 Borgwarner from what I've heard. Check out the drivetrain section at LS1.com sometime, there are plenty of people over there that are having issues with their Tremec T56's. Fwiw, in the change to Tremec they also switched to producing them in Mexico. You hardly ever hear of any of those types of complaints on here about LT1 T56's. I have never had any issue at all with mine, and I've given it some pretty hard abuse at times.

Did any LT1's come with Tremecs? I bought mine off of Blown95TA and it says Tremec on the side, but it came out of a 95. My damn tranny keeps breaking and I want to know why. Any ideas?
