Hey so I have been having transmission trouble lately, or what I think is transmission trouble. It only happens after I get off the highway after driving a bit on that. When I go to accelerate from a dead stop the whole car shudders, and the same from 1st to 2nd but not after that. The reason I think it may not be the transmission but possibly the torque converter is because it does have a slip from 2nd to 3rd that has been there for a bit. It's a 1998 Civic EX. Any thoughts suggestions as to which one it is
