Hello.

1st and reverse are same rod. That's why you can go back and forth between those two.Your shifter isn't crossing over to the 2nd/3rd shift rod.Disconnect the two rods from the shifter, put both shift levers on the
tranny in neutral position, stick a 1/4 inch pin through the allignment hole in the side of the shifter and make sure that it is going through both shifter arms and that the shifter handle inside the car is in the middle position, then re-attach the shifter rods to the shifter and that should get you back up and running.Hope that helps.
