Yeah, so the previous owner replaces his CVT when the problem is something else (e-brake?). Then with the new CVT he gets the same symptoms and continues to blame the CVT. Dealer tells him to go pound sand, so he sells it. Then OP buys it knowing the tranny is a replacement and similarly mistakes the symptoms for the transmission, shells out a chunk of dough on another (unneeded) transmission to save his investment, and is still no better off.
RobMcC, I've got a hunch you should heed the warning lights on the dashboard, not your intuition. If it says you've got a brake problem, you probably do.
