My transmission went out in my 2000 Silverado with over 300,000 miles. Pulled it out last week and called a rebuilt shop and they quoted me $1200 to rebuilt mine in three days. Is this price a good one or should I keep looking. We don't have many shop here in Augusta, Ga. I was looking at the range between $700 to $900. Any thoughts, should I keep looking. This shop gives one year Guarantee . :shock:
