I took my 2014 truck in for a hesitation when shifting and the check engine light was on. John made me leave the truck and he would call me.
John never called so the next day I called he told me I had a major transmisson failure and would cost $3800.00. He was very disrespectful when I told him I was getting a second opinion and said he could fix the problem if I would leave it that day for $1900.00.
I took it to the dealer right up the street and they replaced a shift sensor for $125.00. The service adviser at the dealer told me that Aamco has a reputation for being dishonest its the owner John Mangan not his managers.
Stay away go to your local dealer or independent auto repair shop.
