Hello putting together a 73 Challenger 440 4spd car , car is at the point of driving out of garage ,however I have no reverse ??? fwd gears work fine .Car was off the road for years ,I bought the tranny used ,but all gears looked good ,I changed some seals and put it in car Thanks Gregg

 

I'm guessing you checked the basics !!!
The linkage moves with the shifter?
Shift lever is mounted facing up?
If these are all good I would say it might have broke the shifter fork.... Or the gear is no good inside the trans?


Just my 2 cents.... Keep us posted....
