Yes ,it is still flat.Lesson learned.Try disc on splines first.
Removing the tranny gave me the opportunity to cleaner up the shifter.I remember it shifting easy 20 years ago but when I put it back in the car recently,it was different.After taking the covers off,I could see why.The grease had hardened and become waxy.After soaking in solvent and relubing,it feels better.
Years ago,I was able to go through the gears and never miss one.Should be ready to do it again.
