Jech1997LS400 Posted July 14, 2013 Share Posted July 14, 2013 Hello to all members, I have a 1997 Lexus LS400 Coach edition with 203k. I was driving on the highway doing about 70 and the car down shift and would not go over 40, so I pulled ton the side and tuned the car off waited about 15 min and turned the car on and it shifted normal, but than this happen again only this time it seem to have gotten worst. Do you know what will cause this to happen w/out any warning? Quote Link to comment Share on other sites More sharing options...
pj8708 Posted July 16, 2013 Share Posted July 16, 2013 Hi James and welcome to the Club. I'm going to move your posting to the LS forum where you might have a better chance of getting some information. Paul Quote Link to comment Share on other sites More sharing options...
LEXIRX330 Posted July 16, 2013 Share Posted July 16, 2013 I am no mechanic but it sounds like the tranny to me. I would have a mechanic check it out. Quote Link to comment Share on other sites More sharing options...
