I said about 4 hours. I havent checked the Labor book on this. A Transhop is going to be faster and R&R the trans but that doesnt mean they are going to do it cheaper....I wouldnt. My speed is for my benefit, not yours. You will get charged the labor book regardless of how efficient a mechanic is. Only way you are going to know is to call them and ask for a break down of the price.
