Built allison

Ok so I have a LML, and got a built trans, all is well except one thing, it goes into reverse rougher than it should. Almost like a soft slam into reverse. I was told by the builder it was normal, but it's so bad that the engine down pipe hits the fire wall on occasion because of this when out into reverse.

I put on over 40 k on it and changed to synthetic fluid and new filter, this seemed to help, but still pretty noticable.

Only thing that seems to help is leaving it in neutral for a few seconds before going into reverse.

Any ideas?
