tonight when i came out of work i went into reverse and it wasnt working right it was sort of stuck inbetween park and reverse i think (i did try putting in park and then reverse again but the same thing happened if you know why that happen i'd like to know that to please)so i had my foot on the petal giving gas but barly moving and after i got that all worked out now when i lightly hit the gas in normal driving i hear a rattling noise (to me it sounds like the front towards the wheel maybe even the brake ) but when i'm just coasting i don't hear it and when i'm not light on the petal does anyone know whats wrong? (also this may seem like a dumb question but since this happened tonight i noticed that my automatic shift doesnt lock inbettween reverse and neutral don't know if it did in the first place )
