Hard Shifting

My C6 trans shifts hard until it has been driven for about a half mile or so. Is this normal or can anybody tell me what the problem, I mean opportunity is? Any thoughts will be appreciated.

Thanks

You may need to adjust the VRV (vacuum regulated valve) in the side of the IP. Put a vacuum gauge on the vacuum manifold and see what you are getting from the vacuum pump. There could be a low vacuum due to leaks in lines or the bottom of the juice tin/vacuum reservior.

Could also be low vacuum because the vacuum pump is about to go south.
