That's what he told me with mine. Haven't been able to use it to much yet though.
Mines been in the car for 6k miles now, and it is just an awesome trans all the way around. Mine makes a little whining noise in 1st through 3rd, which he said is likely due to the brand new countershaft and used 3-4 syncro assembly just having slightly different wear patterns. It shifts smooth as butter, but I had him do everything to mine when he had it, its the full street/strip package. Unfortunately the only thing available at the time was a used 3/4 assembly, everything else is brand new inside it at the beginning of this year.
