If you have ever wondered why you cannot put an 18 speed k**b on a 13 speed transmission here is some pictures of the damage caused by doing so. Worked great for a little while until it ruined the splitter gear and lost high range.

Congratulations Jan Gaswint on your retirement. My parents started Black Run Transmission Inc. 39 years ago, so my mom could stay at home with me after I was born. Now that they are both retired they can enjoy the next chapter of their lives. I want to thank them for all the sacrifices they made in the beginning. Thanks to all of our customers over the past 39 years and I am excited to continue providing the same high quality experience everyone is used to.

Thank you all,
Jake Gaswint
