I took my truck because it was shaking every 30-40miles Per hour. In the shop of Aamco that I took It they told me it was a problem with the transmission converter. They charged me more that $3000 to fix the problem. I left the truck with them. They gave me the truck back after 3 weeks. After that there were new problems with the truck that had never happened before it was at the Aamco shop. I had to take it back 4 different times. After 4 months the original problem that I had taken it in for came back. When I took it back they said nothing was wrong. When it was obvious that it had the same problem that they said they had fixed. User's recommendation: Based on my experience I will not recommend Aamco to anybody.
