Hi, I have a 2000 GS400 Platinum Series with 34k miles on it. I am having problems taking the shifter out of park. The shift knob is extremely hard to move. Finally when I do get it into drive, I press the gas and nothing happens, I can push the accelerator to the floor with EASE and it won't even rev. Sometimes, it runs fine though, but the shifter is always hard to get into drive. Could this be a cable problem or a transmission problem? Thanks
