well i just fixed my ignition problems and i was testing my car out and i hit about 110 in 4th and my car started to vibrate really really bad and when i shifted into 5th the gears ground. now when i drive there is a high pitched whining sound coming from what sounds to be somewhere under the bottom right side of the car. anyone have any idea what this could be? and what signs can i look for to tell if my tranny is gone? and how hard is it to rebuild one? cuz i kinda wanted to do it myself if its possible ( im not sure if this should be in talk or not, i thought it was kind of a tech question)
