I have a '95 Honda Civic Ex with the D16Z6 sohc cam vtech. My transmission is messing up. It will go into gear and run fine for a while but after some time it will drop out of gear and not go back in but if i turn the car off it will emediatly work again though for not as long. what could be causing this?

You need to check the connections between the battery and the car. Check both the positive and negative ends where they meet the car and attach to the battery.

i need a wiring diagram where do i go to get it?

you need to get cat conventer checked it could be stoped up

The engine control unit must be replaced as well.

syncro in the transmission is going out. do a trans fluid flush with a GM product called Synromesh FM (FM stands for friction moddified gotta have this one) you can get it at GM dealership. worked great on my 95 civic ex

The 96-98 Civic EX came with an OBD2A D16Y8 engine. That is the only engine that will go in as a direct replacement with your current engine ECU. It's an SOHC VTEC engine that has two extra connections not found on the other 96-98 Civic engines - a VTEC solenoid and a special oil sensor used to determine if VTEC engagement is possible. If you swap in an older Civic engine (92-95 generation) you'll have to convert the car to OBD1 (requires a special adapter hardness) and run the ECU that goes with whatever engine you use. This will break functionality of your OBD2 diagnostics port, and depending on which state you live in will cause you to fail emissions checks. If you install a D16Y8 engine from a 99-00 Civic EX, you will have to swap the intake and exhaust manifolds from your old engine to the new engine, and you will be able to continue to run your existing OBD2A wiring and ECU. The 99-00 Civic EX engines have additional sensors, since those engines are OBD2B. The easiest fix would be to find a SOHC VTEC D16Y8 from a 96-98 Civic EX, as it would be a direct plug and play replacement.

You can determine where your car was made by examining the VIN
