5/21/09 Took my 96 Nissan Pathfinder to Aamco in Arvada, CO for a new clutch because the bearings were making noise. 5/27/09 picked it up and paid 978.13. Drove a few blocks and heard the same noise again. Took it back and they said to drive it a week and the noise would stop. It did not. Took it back and they kept it a week and said they could not hear the noise. I picked it up and while driving out of their parking lot, it made the noise so they heard it this time. But the Manager was not there so they asked me to bring it back on a Monday. I did, they kept it a week and could not hear the noise again so did nothing. I went and picked it up and it made the noise in their parking lot but this time the Manager heard it. They kept it another week and replaced the clutch again. This time I asked for the bad clutch back and they said they had to send it back to the manufacturer since it was faulty. I noticed the check engine light as I was leaving and they said they unplugged everything (must be fuses) and plugged it all back in so just drive it and in 25 miles, the light should go out. Spent the next 2 weeks driving it and having my husband and brother check out the check engine light. Hooked it up to a computer at Checker Auto and it showed the crankshaft position sensor not working. Spent hours trying to find where the part is to replace it because the owner manual said there was a heat shield to remove first from the left side of the transmission near the bell housing by the starter. Ended up paying 48.97 for the part and taking the SUV to High Tech Auto in Arvada (on 8/18/09) who charged me 98.93. They found the part and said the heat shield was so mangled we couldn't recognize it and the crankshaft position sensor was cracked. They said (quote) "Aamco pulled the transmission to replace the clutch and did not remove the sensor first so they broke it." This Aamco in Arvada, CO treats their customers poorly, does not care about their work nor your vehicle and does not know anything about transmissions even though that is supposed to be their focus. The engine light was on and they did not check it and they hoped I wouldn't notice. The worst part about all this is I had to pay extra for parts Aamco ruined and they took many weeks to replace a clutch. They blew my trust in the service and knowledge as mechanics. When I went on-line to find where to post this complaint, I found hundreds of complaints against Aamco Transmissions across the U.S. I also found a General Aamco web site that says they will check your vehicle for you when the "check engine" light comes on because they have the tools and knowledge to do so. Just Shocking. I will never use an Aamco again and I will never refer anyone to them but I will make sure I warn everyone about them. I want this complaint filed for all to see because the Aamco in Arvada is running a bad business and scamming people out of their hard earned money.
