1999 BMW Z3 Steptronic Transmission problem

I am having a problem with my Steptronic transmission in a 1999 BMW Z3 roadster, the warning light on the instrument cluster came on when I started up the car, The transmission worked fine, until the other day the car was parked over night, I was taking out trunk liner to install new cd cable and traced wires. I started car to move it, the transmission warning light came on transmission shifts terribly in auto now I can still put it in manual mode and it will shift ok. I had removed shift indicator last week to check intermittent quadrant light blink un plugged manual/auto selector switch (only manual light has ever been lit while in that mode only lit in auto for 5 minutes one time a year ago) had intermittent warning light after reconnection but warning light went back out when I restarted. Now warning light stays on all the time.. Bad selector switch? Loose connection in trunk? Loose connection in console? I'm not sure where to look.

Tiptronic transmission

Sounds like your transmission is bad. You'll need to take it to a shop to have it checked out.

Dash light came on looks like cog with !

Gear with ! (Automatic transmission)
Yellow warning lamp = The transmission is malfuctioning. Avoid heavy loads. All of the selector lever positions can continue to be engaged; in the forward drive positions, however, the vehicle will be operating in a restricted gear range only. Have the system checked as soon as possible.

Is it normal for the automatic transmission on a 1996 Z3 to need to warm up before it shifts smoothly?

No, this is a situation that involves one or more of the shift solenoids that are inside the pan. These shift solenoids are malfunctioning at this time and, i recommend inspecting the transmission asap for faulty solenoids.
