I an 03 z4 2.5i stuck in limp mode I took down to my local AutoZone and got codes P0306, p0700, p0741, p1732. So for code p0306 it came up cylinder 6 misfire, so I replaced the coil packs as I just did the spark plugs so didn't touch those. With codes p0700 reads / TCS ( Mil Request) p0741 TCCSCP or stuck off and p1732 engine overspeed malfunction, I did a transmission fluid change and filter the oil was dark black and there was lots of smudge like mud build up in the pan on the magnets. After doing those 2 things and checking all plugs and wires car remains in limp mode not sure what to do next if I can get some insight it would be appreciated thanks car has 160,000 plus miles I've had it for about 4 months now.

Not experienced this myself, but I did a search and the P0741 code could point to a stuck solenoid or a bad seal in the torque converter :
