Was looking at the T56's and the early model for the 1993 Camaro and Firebird option M28 Tag ID 1386-000-006 had gearing 3.36 2.07 1.35 1.00 .80 .62 this seems very close to the stock X tranny of 4.17 2.19 1.49 1.19 1.00 .85 has anyone run close to this in the T56 and not changed the differential gearing? Thanks for any help........

The gto m12 t-56 works great with stock gears. Well, at least with an LS2. Sit at 1640rpms @70mph in 6th. Actually can use 1st gear now too.

Are you running the stock X-runner rear end? What year is the GTO setup?

Thanks, Karl

My engine and trans are from a 06. The m12 was only found in the 05-06gto. Im running stock 3.15s, but have an open diff that has been miller locked.

Thanks! Was hoping Gadget would let us know what he is using. Will have to just ask him. The early T56 is very rare and it may take less time just to get a magnum done.....
