We just picked our Super Charged Denali XL after having a complete transmission rebuild. Everything was done as agreed. Never knew how bad our transmission was prior to the build. So far we are thoroughly happy with the build, it's day and night from where we were.
On another note, we were very straight forward as to what we wanted. They were just as straight forward in return with us with no hassles. There was no bullshit from start to finish.
