I just bought a 93 sunbird to commute to school with. Drove it home fine then today on my way home from school the car starts vibrating and it sound like it is the transmission ! Car has the 2.0 ohc motor. Some things I noticed different from the first day I drove it are; takes alot of gas pedal to get the car moving,vibrating/harmonics coming from the trans tunnel,speedo gauge moves up to 40 if I have it in neutral and rev it up.
Could it have something to do with the torque converter,maybe some sort of switch?
Hoping for the best,any help greatly appreciated. Thanks in advance.
