1G Where is the VSS?

[dsmdreamin]

hey everyone, I pulled my codes tonight and a couple days ago my buddy and i were out testing the new prosport boost gauge out and i did a mild launch and after words we noticed that the speedo wasnt working, so tonight when i pulled my codes it came up vehicle speed sensor,(and knock sensor too, what does that mean, is it tellin me its bad?) so i searched but am unsure of where this speed sensor is exactly on my 90 gsx? or could something have just came loose from the motor/trans swap not done too long ago? please help.

thanks,
Justin

Check the connector for the vss on the tranny (on top rear). It comes loose easily.

And if the connection is good, pull it out to inspect the pinion.

yeah... mine is acting funny too.. I went about 120 on the freeway the other day (yes yes yes I know... 120 is bad) just for fun, and I noticed when my car would dip down when I would go over a bump (I have stock suspension so its kinda boaty) the speedometer would move up and down with the motion of my suspension going up and down.... But I was still floating.. No drop in speed except for what the speedometer said... It was just weird... The car goes down, the needle on the speedo moves...

and when I pull out of the drive way or Im at a stop light, it wont read any speed until about 15 mph
