Car was towed to aamco later was told transmission had a gear ratio code...was also told the transmission was damage and nothing can fix the problem...it would cost around $3500- $3800 to fix ....is there another route besides what I was told also might have to replace torch converter , replacing the electric plate would be point less since it had a gear ratio problem...is there another option to fixing this or am I left with getting tranny rebuilt?????
