Tranny Problems

Just got my car back the tranny shop got a 97 Deville about 103 and some chang on the odometer the car takes off in second and shifts fine through the rest of the gears but it will not go into first gear even if it is manually shifted the shop said that it was an electrical issue causing this problem has anyone encountered the same issued with this vehicle if so would you be so kind as to share thank you-95ISS

Needs to be scanned with a trans function scanner for diagnosing the shift patterns and solenoid functions, if it was overhauled they need to take a look at this.
