When swapping these types of ECU's it's common to modify the Air Intake leading to and from the Mass Air Meter. this can change the calibration of the mass air. Depending on the ECU it can fail the mass air table and revert to the VE table. The transmission should not effect the function of the mass air meter. Transmission issues typically are incorrect harness or mis matched ECU calibration to the 4L60E.

The mass air issue can be tuned in the MAF transfer function or change the operating system to speed density and tune using the VE table.

I work for Holley so my suggestion is the Terminator X Max. About $1400 complete and has trans control.
