SMG not shifting

Just did a engine and smg transmission swap from a 2003 m3 smg to a 2003 m3 smg. Engine starts and runs fine. SMG trans will not shift. Codes came up P0760,P1740,P1848, P1850, P0763, Replaced shifter and transmission control module, unpluged all 3 hood switches no luck. Put test light on gr/wh and rd/wh wires that come out of control module for the hood pins and test light wont come on when it is grounded or hot. I have replaced the salmon relay, I have checked the wire plug to the trany several times, they are all clean, pins are stright and plugs tight, clutch and hydraulic fluid all good. It goes in R, 1st and 2nd on the dash window some of the time. You can hear the hy pump when key is turned on. And a clicking like its trying to shift some of the times. But the transmission will not engauge. When unlocked you can hear the pump motor running.The trasmission worked fine before the swap allthow the car was rolled. Two of the codes are shift solenoid and two codes are no ground, plates A & B. I did run a battery cable to the trans from the frame to make sure it was grounded, no luck. The service engine, brake, trany lights are on the dash and will not reset. The battery reads 14.3 volts when not runing, allthow when running the car for a half hour battery went dead, will test alternater and probley replace. must have burned it out with battery charger. Any advice will be greatly appreciated. Thank You
