I do my own work now which means I fix other problems that people have left for me. The last time they removed the transmission pan from my car, thanks to the mechanic, I pulled the threads off. He squeezed the breech too hard, tearing the aluminum thread. Using this product I followed the directions and smeared the threads with some Loctite and the fastener went in perfectly and tightened up to 90 inches per pound. I was a little scared drilling my gearbox but this product helped me. It's definitely worth the price.
