SMG Shifting Issues, yet no codes... Help?
2006 M5 with 88k miles. Ive never had any faults or codes or cogs, yellow or red. But the other day, driving around town, shifts between gears were taking about twice as long as usual, in all gears. For instance, going from 1 to 2, the display would read 2 right away, but would blink during the lag. At about the time where the shift would normally end, the rpm's start to drop. so when it does finally drop into gear, it drops harder than normal. Cruising at very slow speeds, (like in a parking lot, 1-3 mph) is pretty rough, like someones first time driving stick. Ive never experienced any clutch slippage or grindage. the trans fluid was changed about 4,000 miles ago. A few months back I had some minor body repair done, shop had it for a little over 2 weeks waiting on insurance. When i picked it up, the guy in a half assed confession basically told me my battery wasn't good, possibly because they probably left the trunk or door open while they worked on it. now, when the car sits for a few days to a week, the first start takes maybe 1 or 2 seconds longer to start than before. Doesn't seem like a big deal, and don't know if its related, just trying to get all the info out there. So thats where Im at, with no codes to show for it. I called one shop and they recommended driving it more till it throws a code. Im just looking for some ideas as of where to start. Feel free to ask if I left any info out that might help. Thanks in advance!
