Guaranteed Automotive & Transmission Service of Lafayette, IN has been in the transmission repair & service business for over 35 years. Our auto mechanics are so trusted in transmission service that other car repair shops and dealerships in the area often send their transmission repairs to us.

We were primarily a transmission shop in the 1980s, 1990s, and early 2000s. Then cars became more complex and we started doing general auto repair in 2007. We brought on an extra automotive technician, in addition to transmission specialists. And now, after 35 years, Guaranteed Automotive & Transmission Service is still Lafayette’s most trusted transmission repair & service specialists. We’re so confident in our transmission repair and service that we offer the best warranty in the Lafayette area, all transmission work comes with a 3-year/100K-mile warranty.

We could go on and on about our transmission repair & service, but don’t take our word for it, check out what this customer said in their 5-star review:

“I am glad to have a shop like this to go to when one of my trucks needs transmission work. I had not to long ago had my transmission rebuilt by another shop. After only 20,000 miles, I lost 4th gear and overdrive. After all the troubles I had with the previous shop not standing by their work, I was hesitant when I came into to Guaranteed transmission. All i can say is, what a great experience. It's nice to see customer service in this day and age. It's a rare thing anymore.They went through my transmission and transfer case and found the valve body clogged up with a glue that is used to attach a part to the valve body. They could have easily told me the transmission was toast. But, they didn't. They cleaned the valve body, put it back together, and had me on my way. It eases my mind to know there's a shop close to home you can count on!”
