Even though we installed DTS 3.73:1 gears in place of the stock 2.73:1 gears, we didn't pick up the e.t. gain that we hoped for, because our stock torque converter would only allow us to stall to 1500 rpm. The low-rpm converter was killing our launch as well as our e.t.'s. Thus, while the engine was out, we ordered a new torque converter from TCI. The new 11-inch Break-A-Way converter (PN 241502) features furnace-brazed fins and needle bearings and stalls between 2600 and 2800 rpm. Plus, the unit was a direct bolt-on.
