Recommendation on transmission builders in Minnesota

[MN250R]

Hello, looking for reputable builders in MN that are familiar with our 200r4 GN trannys. I had mine done years ago, but have never been real happy with the outcome. SHifts real hard from first to 2nd, even with the TV cable properly adjusted. Looking to see if someone can look at it. Thank You!

Just stick it on a wooden pallet & ship it out to any of the following specialists :
David Husek (TurboBuick Performance), Lonnie Diers (Extreme Automstics), Janis Transmissions (Vince or Chad Janis), Steve V’s Garsge (Steve Vaillancourt),
You can’t go wrong with any of these , there may be a few others as well (sorry if you were omitted from my post).
Please feel free to update the list
