On Saturday, 24 August2013 my 2003 Acura MDX started to have issues going in and out of gear. I had the car towed to Mr. Transmission on that same day (24 August) and spoke with Adam who informed be that they would inspect it and let me know if they found any issues. After finding no internal issues Adam informed me that they would have to remove the transmission and inspect the internal components. Adam stated that the total labor to rebuild the transmission would be $925.00, which included removal, inspection, rebuilding and reinstalling. I then asked Adam how much would the parts be, and if I was looking at more than $500.00 for parts. Adam stated that the parts may not be exactly $500 but they shouldn’t be much more than that. With the parts and labor that would bring my total to ~1500.00 with a 1 year warranty. Adam called back on 27 August and informed me that after inspecting the transmission that I would have to replace the valve body, a few bearings, a shaft, drum, and the converter. He stated the valve body was mangled beyond repair and transmission shaft was broken and they both would have to be replaced. He stated that all of this comes with the rebuild kit for ~$500 with exception on the valve body. So I then asked how much would the valve body be and he stated ~$1000.00. After receiving the news I asked Adam for the total price now that we have to replace the valve body and he quoted 3,804.83 which is more than the price would be if I added up all the values given ( Labor $925.00, Rebuild Kit ~$500.00, and Valve body ~$1,000.00= ~$2425.00 plus tax). From there I asked how I incurred the additional cost, he then proceeded to naming everything that was already included in the rebuild kit for $500 which I did not understand. So I notified Adam that I would shop around for a used transmission and could they install it, he said yes. I found used transmissions for ~$1200.00 and REBUILT (same thing they would be doing) transmissions for ~$1500.00. After speaking with Adam and prices not lining up I then called Jerry Damson Acura (Local Dealership) inquire on the price of a new Acura transmission valve body, and I also checked internet prices to see if I could get the valve body cheaper somewhere else. Internet prices for a new valve body were ~$300.00 and the DEALERSHIP valve body was only $500.00. The dealership parts were $500.00 less than what Mr. Transmission was trying to charge me for the part. I then told Adam I would prefer to have dealership parts which are always better than aftermarket parts and he refused to do so. During this time my wife and I decided to just trade the car in. The dealership that we were dealing with did not want the car reassembled and were going to send a tow truck to Mr. Transmission to pick the car up and not have him do anything else to it. Adam refused to let the vehicle leave without putting it back together to receive the full $925.00. I told Adam I would pay him a percentage (~$500.00) for his services since Mr. Transmission did remove the transmission but they did NOT rebuild it or reinstall it. Adam refused and said he would not let the car leave without full payment for HALF of the service. After stating this I asked to see the bad parts. I then proceeded to inspecting the so called mangled valve body and broken shaft. Neither the valve body nor the shaft had a single scratch on them, they actual looked almost new. I then asked to speak to a manager or district manager and he refused this additional request.
