Hi I just got back my car from auto transmission shop.
I got suffered from shudder when 60km/hr, around 1500rpm and light throttle. First I tried auto transmission oil flush but still same.
So I decide to bring my car to shop and get a qoute with diagnosis. They checked and confirmed torque converter problem.
Let they work during 4 days for torque convertere reconditioning and I paid $1300 for it. But the problem is I checked that symptom when I came back home. First 20min I couldn’t speed up due to traffic. After then, I tried test and realized that it isn’t repaired and they did wrong diagnosis.
In this case, I want to refund money for they did wrong diagnosis what can I do
