Ok well i tought i threw away my old 95 dohc mtx pcm when the shaft striped out inside it. But i found it in the garage today and took it all apart to see if i could get that shaft out and i did. So then i figured id put it in my project neon witch is a atx and it works but my question is. I tought it was supposed to throw the cel because of the lock converter but it didn't the number on the pcm iswritten like this.

Is this an atx pcm?

 

Did you drive the car? The lockup torque converter doesn't kick on unless you are above 55 mph or something like that.

 

Ok that would explain it then i only took it to like 35 mph thanks das.I have another question what do i put on the computer board to reseal it. It looks like silcone that i had to take off to get that shaft and bolt out.

 

Not sure, but you could try some clear silicone.
