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........
