I must of missed that post or read through it too fast. I've never been denied 3-->2 shifts but I haven't taken her to autox or the track. Just some hard street driving
The issue I have is winding out 1st and grinding 2nd and being denied into 2nd. It only goes about half way into 2nd and I have to go back to neutrel then back to second, by then the RPMs have fallen. That being said, I usually just get moving with 1st, then easy shift into second before getting "on it". I've even had this issue just running first up to 5k, not just redline. Sounds like I "might" benefit from a tranny oil swap but maybe not. Or maybe it's just time to Frankenstein a M3 tranny in there. Or just baby 1st.
