I car just went into Fail Safe Mode Transmission. Codes read PO720 & PO732. on 1998 BMW 740iL

When I first started car and then put into drive it moves slowly and when I reb up the Gas it jumbs into to another gear and then goes to the errors codes. I flushed my Oil recently to see if that will loosen the gear...but did not work. Code PO732 also indicated the Trani. Output Speed Gear 2 Ratio has malfunctioned. Does move in Reverse fine and when in higher speeds, is good. I am assuming the Output Speed Sensor needs replacing. Can it also be wire harness inside the Trani. Pan the needs replacement? Please help. Thanks, JR
