having a hard time finding the part numbers here...................but is our torque converter the same as the 45RFE found behind the 4.7 and 5.7s with the 45RFE?

5175969AB - may be same as 4.7L, but def not same as the Hemi - the Suncoast CRD TC is the Hemi version, race-hardened

Primary differences in the 45\545 grouping are aggressiveness of the impeller and turbine vanes - other than that they interchange - if you need a high-stall number, use the KJ CRD tc on the Hemi to keep the rpms up in the Hemi power band - at least, it will..............until the plastic stator shattors..............

Four in a row really makes it go

The part numbers aren't the same due to internal differences (stall speed / lockup clutch material) but they will interchange. The most likely difference you will see is the different stall speed.
