I replaced rear main seal, 2008 Silverado 4-wheel drive because shops wanted $2500, I’m retired and on a fixed income. After reinstalling the transfer case I shared with a parts tech that trans fluid came out when removing transfer case from transmission. He said it should be dry, replace the transmission output shaft seal. My wife was against me doing this job saying call Graham Auto. Oct. 2, I called and talked with Rob explaining the scenario. Rob provided an estimate of $223.32/$265.15 with tax and other charges. Rob got vehicle info using the vehicle license plate#. We also talked about the trans neutral safety switch as I could not get it plugged in. I made appointment for Oct. 11 for replacement of the trans output shaft seal. Oct. 3, I met with Rob providing a printed picture of the trans output shaft and verified that fluid should not have come out during transfer case removal. Rob provided confirmation. Oct 11, arrived for appointment. Provided Rob with printed picture again, asked about cost to also replace transfer case seal. Rob asked about the neutral safety switch, I was impressed by notes kept. Rob took the provided picture and talked with the mechanic. Upon return Rob handed me a printed estimate of $846.02 to replace the trans output shaft seal. My jaw hit the ground! I expressed my surprise recapping our previous discussions and pictures provided. Rob mentioned something about now having the vehicle like this provided him with information that he didn’t already have. I did not understand this comment. Rob asked if I wanted the job dismissing my response saying “what it is, is what it is.” “I told him no, I can’t afford that!” He again dismissed my frustrated response. He told me to “have a nice day.” I regret telling him to “___ off,” that is not something that I would normally do. I understand that people can make mistakes. I would expect that a business making that big of mistake would offer a customer discount. I will not go to Graham Auto again, and will share this experience with my friends.
