Mike Kaz and his crew have rebuilt a number of transmissions for me personally, and for Snellers Landscaping. They have a quick turnaround when needed during a snow storm, which is awesome. They have the capability to upgrade and build you're transmission for the specific need of that vehicle. They are the only ones that touch our transmissions!  
Thanks guys!

Quick, Affordable, and Knowledgeable! I looked at 2 other shops in Hudsonville who both tried way to hard to oversell themselves as the "only option". Josh and Swamp at Kaz transmissions didn't have to say a word. They ARE the only option. These guys know transmissions. I had my car back within 48 hours of dropping it off. Save your time, money, and aggravation you will get dealing with the competition.
