upallnight thank you so muh for your links

I have been riding with my X and it has been working fine. While cold the reverse always work perfect, when hot, iw wasn´t working but I discover a to make it work. When I put reverse with hot engine, the reverse engage, and moves 3 meters and then it stops and loose the ability to move. To have reverse again, I put on "P" then on "D". I make this procedure twice, and then I put "R" again and... BINGO... I have reverse again Then for the rest of the day , no more problems reverse works perfectly!!!! It has been like this for the last three days!! Isn´t this weird?
