This sounds like the same thing that is happening to my car, I just swapped a type R engine into my 95 civic. Got it all put in and started just fine, reversed out of the shop, when I went to put it into first, nothing. Now I can shift through all the gears without the clutch in and it never grabs, I just replaced the clutch, pressure plate and throw out bearing. Still nothing. Also as I shift the speedo changes, the higher the gear the higher the speedo sits, 5th gear, around 20 mph. also when I rev it the speedo goes up also
