My car doesn't move when I put it in drive or reverse. I changed transmissions and it is still doing the same thing. I have a 2003 escalade. I got the new transmission from a friend in which was sitting in his backyard for months and so was the torque converter to go with. I can't get to the core of the problem but I kwon that it is very rare to have the other transmission put in to find out it's doing the same thing. What do I do? Mechanic's Assistant: Do you have the torque specs? I'm not even sure what that is but I assume it goes to the torque converter. Mechanic's Assistant: Are you fixing your Escalade yourself? What have you tried so far? I have a personal mechanic. I've tried replacing the whole transmission. With the torque converter being outside for a long period of time. So I took it to a real mechanic and they automatically told me I needed the whole transmission rebuilt in which would cost 1@55 Mechanic's Assistant: Anything else you want the Mechanic to know before I connect you? $1500
