Default In nuetral jacked up, rear wheels move when rev'd

I had the car jacked up, but in nuetral and the parking brake off (all 4 corners on jack stands. I reved the engine from the butterfly under the hook, and noticed the rear wheels spin a but when I do this. Is this normal, or was my new clutch not adjusted/installed correctly? Thanks.

Not an expert but I would venture to guess that maybe you are transferring a bit of power from the motion of the fluid in the transmission.

Take a look here: http://auto.howstuffworks.com/transmission3.htm

I think what you are seeing is a small amount of friction between the blue gears (in the 5 speed diagram) and the shaft leading to the differential which causes it to turn, even though the dog gear is not engaged (ie. shifter in neutral.)

Great link BTW

I'm about to try and rebuild a trans. Ive had one apart, and of course I have the service manual, but this is great. It gives you a discription and visual picture of what all of the the inner workings actually do.
