Hi Guys I Need Help! I Built A Motor B18B1 With A B16 But When I Bought The Tranny The Differential Was Messed Up, I Replaced It Closed The Tranny Dropped It In The Hatch But I Gotta Shift Hard On Every Gear And Im Not Getting Reverse I Want To Know What Could It Be Thats Making It Do That!!

 

Sounds like the transmission was not assembled correctly. If the reverse stopper plate is not aligned correctly with the upper casing you caused some damage.

 

I did it right but I just noticed I have a bolt that goes on the top missing idk if thats why is doing that and idk if that bolt does anything to the reverse to catch it

 

Likely the reverse idler shaft bolt....
