P073D:00-TCM: Turbine/input shaft speed sensor: Sensor output range malfunction P1738:00-TCM: Automatic transaxle internal malfunction This concern is caused by improper TCM logic.

About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
