My transmission took a dump today

FIXED IT!!!!! I had to move that arm it was reading wide open throttle instead so it was essentially waiting till the last possible moment to shift j par thanks for the insight it was exactly as u said
Make sure it's hooked to your carburetor and working exactly as it should. now if it goes the other way it's even worse because it will go right into 3rd gear quickly and not put any pressure on the pressure regulator and blow up your transmission lickety-split!
