AAMCO Transmissions review: Transmission replacement/warranty

Had to have ransmission replaced. Aamco in Rolla Missouri did the work. 36 month warranty was included. I drove back to Wisconsin, where I live. After about 1500 miles, the new transmission failed. I called Rolla AAMCO, and after 3 days they told me I had to get my car towed to an AAMCO in Brookfield, WI, which is about 75 miles. 400+ dollars for tow. Now the Aamco at Brookfield has had my car for nearly a week, and is telling me they are waiting for either the Rolla Aamco, or the company that made the transmission to authorize the repair or replacement. After spending 5, 500 dollars to date, I remain without a car, and having no clear answers as to when or how it will be fixed under their warranty. All I know for sure is that I will never recommend AAMCO Transmissions to anyone in need of a transmission repair.
