Just randomly, I parked my car and when I went to drive it again, 1st gear does not work at all. The engine isn't free revving and I can feel the load transmitting to the trans, it's just 1st gear wont go anywhere. Once I hit around 2.5k, the car just starts bucking. 2nd works, and 4th is a little weird. No codes are being thrown and no fluid leaks are anywhere. Anyone have any suggestions?
