So i just got my b16 running in my hatch and when i'm driving in 5th gear, it will occasionaly push itself out of gear. It's done this at all different speeds, 45, 60, and 75. When I'm driving in 5th, i can push forward on the shifter and it will stay in gear, but you can feel it try to push out every so often. Please help.

 

you have to open the gear box...

it's either the syncho sleeve for the 5th or the teath-cluch for the 5th gear!


btw, while you are at it - check all of the gearbox!

You're looking at transmission surgery, no matter what. Grab a helms manual, a socket set, a snap-ring tool, and all the measuring gear you can, and get on it. Everything you need to know is in the manual. Fair warning, use the metric measurements. The english unit conversions are wrong in a few places.
