I have had my '84 Carrerra for six years. It is a second owner car that I cherish. In January 09, we moved from SoCal to Omaha, NE. When the car was transported out here, I began having shifting/grinding problems with the 915 box.

I checked several local "Porsche" shops before finding FLATSIX in Bloominton MN. Aaron Hatz is the owner/technician. I, of course, assumed the worst and agreed to have him rebuild the transmission. He drove down to Omaha with his enclosed trailer and took the car back to MN. A few days later, he called me and said he had found the problem. Turns out that several of the transmission mount bolts had fallen out. He replaced them and told me the transmission shifted fine but the clutch was aged. We went ahead with a Sachs Power Clutch Kit and the car works like a dream.

I am a longtime car enthusiast and have dealt with thousands of shops and situations. I know when I am getting BS'd and because I'm now disabled, many operators try to talk over me, or past me. Aaron also did leakdown tests, compression tests; than adjusted the valves and assured me that the heads were in good shape.

Aaron's honesty and love for Porsches shined brighter than any experience I have ever had. I recommend Aaron to everyone. He is honest, knowledgeable and reasonable, not attributes you always find as a Porsche owner.
