This doesn't sound normal for a miss; a miss is usually dependent on engine RPM and/or load. Are you sure you aren't experiencing some odd phenomena with the lockup torque convertor? the PCM commands lockup at this speed, and will apply lockup in 3rd and 4th gear, but not 2nd or 1st. You can just disconnect the connector for the convertor clutch from the trans and drive it; it wont set an error code and you can rule it out for sure this way.
