Broken heart

We’re not sure what caused the lockup.

Well, glad everyone is OK, that looks like it isn't too awful bad.

What shifter are you using. Right after I installed my Hurst Promatic 2 I took it for a spin. 1st A OK, 2nd A OK, and then I hit third at 50 to 60 or so, rear end locked up and set me sideways in the road.

I gained my composure, pulled to the side and the trans seemed fine, and come to find out it was. It turned out the shifter cable was adjusted off just enough to send it to reverse.

I made some adjustments and it was all good after that.
