I have a 97 gmc K1500 with a six inch lift on 35's. I need to find someone that can rebiuld the transmision for a good price. I was quoted 1500-2500 for a stock rebuild. This seems a little high to me, and I was hoping to possably upgrade the clutches and whatever else to help with towing. Is this a good price for the stock rebuild? If anyone has anybody has a recomendation of where to take it or what I should expect to pay I would really appreciate it. Oh yeah, it's an automatic, (4L60E I believe).
