transmission on 1998 BMW 323is

I just replaced the cars battery and now the tranny kinda jumps or kicks when entering or coming back down to first gear. I had the fluid power flushed with cleaner and new fluid installed but to no avail. Codes read were torque converter and can load. Any suggestions?

If you replace the battery on a BMW you often/usually have to do a shift adaption, throttle adaption and fuel system adaption. have a sharp BMW tech clear all your codes and re-set all the adaptions for starters. Then let me know how that went.
