Hi everyone, I sold my e46 318i last week and bought a z3. My e46 is alot different from my z3! my e46 was a single cam 318 and the z3 is a double cam 1.9 however the e46 got up the hills ALOT better. Im going to get the z3 a good service with new fuel/oil/air filters, etc.. As its quite gutless.. However i just wanted to know if the trans in the z3 is different? the z3 doesnt change down gear when im going downhill or when i brake. The e46 would always drop a gear as if it was manual. Im just wondering if the z3 is meant to do the same but my trans isnt operating correctly? also is the z3 meant to be quite gutless?
