I went on a cruise last night, and it was glorious. I was finally pushing the car and holy cow she is fast! I did a launch to get some practice back in, and the shift from 2nd to 3rd never connected. It never shifted well at high RPM from 2nd to 3rd. Whatever happened, it never went in to gear. The shifter then was completely loose, and could freely travel front and back while driving.
It’s currently stuck in 4th gear. I took her to Archie and we checked it out. All the linkage under the car is connected and looks fine. So, its likely the shift fork inside the transmission. Crossing my fingers it’s ONLY the shift fork or pin. FML.
