Aamco Transimission, Mcdonough GA Shaky work, lot’s of excuses McDonough, Georgia!!. I am having a really bad experience with the Aamco in McDonough GA. I took my 94 Chrysler LeBaron in because the transmission failed. After inspection, they told me they needed to “rebuild” the transmission. Original price was to be $2,000.00, but after some negotiating a final price of $1,500.00 was agreed upon, with the understanding that my warranty would drop from 12 month’s to 90 days. The boss/owner, Shane assured me that I would receive the same level of service, regardless of the discounted price. Well, my car has never been right, and is STILL in their shop, in undriveable condition 2 months later. I would avoid this shop at all costs!!
