I have exactly the same problem with my E46N42 after I changed my ATF. I talked to 2 different mechanics and they have encountered this problem with other E46s as well especially after the ATF change. (Apparently, It also happens to Hyundais as well)There was absolutely no issues on the diagnostic machine as well. Both told me that you should not change gear until the temp reaches more that 40c on cold starts or when the car is left idle for more than 8 hrs.  I personally called Che' Mat (the JPJ Engineer Director) in the Traffic Section on TraxFM twice as well and the advice given was CHEAP and EFFECTIVE:1. On cold morning starts - run the engine about 1/2 mins.2. Engage the gear from P to N to D to S and then to M1 about 5 secs each to get all the fluid flowing in all ports.  3. When you hit M1 you will DEFINITELY feel the gear locking as this is the lowest gear.4. Then only you move back to D and there will be no problem. Or you can go move at M1 for a few meters and then switch to D.   You will notice that this sometimes only happens when the car is idle for more than 6/8hrs so I guess it has to do with the temperature.       So far this proves to be effective and there has bee no issues after that. Or you can try to flush your ATF again but I dont see it as an issue.</blockquote>
